    Trig TT31 Mode-S Transponder with ADS-B Out capability
    i'm upgrading my panel and intend to swap my TT31 Transponder to a TT22 remote unit controlled through my new efis. I am therefore selling my TT31 including an ACK A-30 Alticoder, wiring harness and mounting frame. I'm asking 1780 USD + shipping (from switzerland, so that's going to be probably around $100 to the US). with an appropriate GPS source attached to it this Transponder can fulfill the  ADS-B 2020 requirement (according to the webpage below, i'm no expert regarding us rules though)

    well i guess i should have posted this to the "dumb stunts" forum i called the seller and he agreed to take it back and pay most of the money back, minus some $$ for packing it up etc. but that's allright.. i don't think he knowingly sold me chunk and after all i could have looked closer at the original picture he posted in the ad which was low res but still good enough to see the geometrical differences between his mount and the avidkitplanes one.
    so after all just a dumb stunt that cost me a few bucks to learn a lesson  
    so in case anybody out there has a 912 mount for my avid, please let me know i'm still interested!
    this at least helps me to understand, how we got to the over-regulated stucture in aviation as we know it. in switzerland even experimentals are quite regulated and anything structural needs to be verfied by approved engineers and stuff before you are allowed to mount it to your plane.. for exmaple this engine mount, since i can't prove with pictures that it has the same structure as the original and since it is obvious, that it was not welded professionally would probably never make it through the final inspection before getting the permit to fly.. i'm not saying that i agree with the politics, that we need to save every idiot's live by taking away the freedom of everybody else and over complicating things, but at least now i understand, how this specific regulation probably got into existence..

    Paul, are you saying that the original mount is also different in its design (like where the pipes attach to and all that)? that would mean i can't even use it as a template
    EDIT: i can actually answer this question myself.. looking at the avidkitplanes engine mount it is clearly even a different shape.. the upper and lower connecting rods between the round mounting holes are straight here and bent in mine.. also the round mounts look far bigger and seem to have a different shape alltogether.
    geee.. i'll try to convice the seller to take that think back.. thank you all for confirming my observations (and i'm happy to hear that this is not the quality level of the rest of the plane ;))

    Fred i have to tell you something my 2.5 year old son really loves your videos. his absolut favourite is "Barbecue Tignes 2019" which he calls in swiss german somewhat like "airplane snow" .. watching "airplane snow" is probably my ultimate trump i get to play when i want to get him to agree to do stuff he does not want to do, like go to bed in the evening or take a bath before doing so.. usually the deal goes like "okay, we will watch airplane snow once and then you go to bed" .. of course in such situations the bargaining does not end there and he usually manages to squeeze in Wellness Firday as well as the taildragger brotherhood .. not that his father would mind watching those together with him on the couch in the evning
    i'm happy to have another one to add to the list, especially since this one features HB-YMX which was the very Avid i got a chance to fly before i decided to buy and hopefully eventually finish building the one i have now keep posting. I hope that one day we will meet at such a fly in or somewhere on a moutain strip

    I bought an "original" 912 Mount
    Hi guys. i am in the market for a 912 mount ever since i bought my unfinished avid Model C over a year now i have ordered two replicas of the original avid mk iv engine mount for hte rotax 912 from two independent sources (one from avidkitplanes, the ohter one is a guy in the netherlands who supposedly has a jig and offered to produce one). both orders are pending since last spring and neither of the two has delivered anything (in all fairness, they haven't billed anything either, so all is good).
    Imagine my excitement, when i recently found an Ad on a german UL site, where someone offered an original, unpainted, unused 912 mount for the avid. I immediately called the seller and bought the thing. Today I got the parcel and anxiously unwrapped it.
    Well that was a bit of a shock, because what i took out of that box looked as if i had tried to build an engine mount myself, an i have no clue about welding! all i have is a cheap mig welder with a low and high power setting and i use it like a hotglue gun, only hotter! to my eye, the engine mount i got looks like it was produced by a person with about the same take on welding as myself.
    so those of you familiar with either welding or the build quality of the original avid parts, can you please take a look at those pictures and tell me, if against my intuition, this thing could really be trusted to hold a 100hp rotax at the front of my avid?

    it does sit flat on the floor, so whoever built it seems to have had a jig at least for the firewall or it was welded directly ont he firewall,

    the different bows are not all in the same plane.. they don't really form a ring. not sure if that was even intended but it sure looks a bit off like that.

    that's what i mean by "hot glue only hotter" .. this is exactly what my welds look like, and i too take a grinder to it afterwards if i want to make it look pretty

    this pipe shows "wrinkles" from bending it.. it seems to have been bent by adding dents on the inside rather than forming it with a rolling tool.

    on one of the two larger arcs, there is even a serous dent which looks like it happened either when clamping, hammering it in place or while bending the pipe.

    one of the straight pieces at leas shows the letters "MIL" which seem to indicate this is some kind of military grade material

    the bushings are all marked with probably some angle numbers, 42°, 40.5°, 41° and 38° if i interpret them correctly

    some of them look like they had a hard time so far.. a few dents are probably from storing and shipping it around, but most of it seems to have happened in production already.

    so many different colors and so much grinding.. with the little experience i have, this really looks like no one could guess what the material strength at this attachment point really is. i did things like that for little push-carts i have built and these where exactly the kind of joints that would crack up and break first.

    even though everything looks like it was never used, this pipe seems to have some primer or something left on it.. so maybe it was scrapped from somewhere? or is that only a protective paint that's put on the raw stock to preserve it?

    If i had mad this, this would be the weld i'd show everybody and brag about .. it is also by far the nicest on the entire mount and accessories.

    so please tell me what you think about this mount.. maybe i can at least use it to build a jig and then hand it over to a real welder to produce a safer replica of this..
    i have to say, i have never seen any original avid parts in a raw state.. i bought my avid fully covered and painted with a rotax 582 at the front which did some ground runs 20 years ago and was then left sitting in a shed, so that one really needs to go and i want to replace it with a 912 before the maiden flight of this avid.
    by the way, i've payed about 750$ for this.. compared to a new one from avidkitplanes for 1000$ this seemed like a fair offer for a 2nd hand part... not so sure about this deal anymore.

  7. Pascal added a post in a topic iPad EFIS   

    i am currently building a panel with 2x 8" android tablets and 1x MGL MX-1 (8" portrait mode) .. it is not for an avid though, the panel is higher than the avid's. On my avid i plan on using the MGL iEFIS 8" display in landscape mode. the MGL's are extremely light, actually so light that they feel a bit flimsy when you hold them in your hand, i had really expected more weight. I will use the MGL as my primary flight display and have added a Talos Aeolus sense which is connected via WiFi to the tablets to provide a backup ADHRS (that's mandated even for VFR if you rely on purely electronic gauges here in switzerland). For the tablets i have built some custom mounting frames which flush-mount the tablets from the back to the panel. I have 3d printed those and added the 5v power supply and a 5v 40mm fan to provide additional airflow for cooling the tablets. In my previous plane i was using another Huawei 7" tablet as my nav display and i had it mounted on the panel in the sun and it never overheated..
    i have also heared, that newer ipad's don't overheat as much as older ones.. no idea if that holds true but i think as long as you cool them with a fan they should be fine.. there are also nice panel mounts available for ipads.. don't recall the name of the manufacturer anymore, but you will find it if you google for it.
    here is a picture of what it is going to look like. currently the panel itself is just a thin mdf sheet that i have routed to test the fit of everything before i make the final panel in aluminum.

    here is a picture of the 3d printed mount.. it attaches to the panel from the back and the tablet is just held in there by the panel pushing it into the cutout. the whole mount is about 140 grams (only 15% infill was used for the plastic), it is printed in a speacial PET-G plastic which is flame retardant. I have cut some holes in the back of the tablet and soldered in some wires to bring the power button, volume buttons and audio out to a SUB-D 15 pin plug so i can connect it to the wiring harness. i also had to move the usb connector for charging the tablet to the back because as you can see on the above picture, i was quite limited in hight and cound not afford to plug in a usb connector at the bottom of the tablet. but all that is nothing a dremel can't solve for you

    @Iv2plyguitar: may I ask if you had to modify anything from the firewall back like the geometry of the vertical stabilizer or elevator? I've learned that they are slightly tilted to compesate for the propeller wash of a 2-stroke which turns the other way and read that the Model IV does not have that anymore, they seem to have straight stabilizers and elevators instead. how did you fix this on yours?
    I have a model c which i want to finish building with a 912. original MK iV mount is on its way to me.

    2020/07/31 - 08/02 Switzerland EAS Fly-In
    For those based in europe: the swiss EAS (basically the swiss version of the EAA) is hosting a fly-in on the weekend of july 31 to august 2. 
    The full details for the event can be found here:
    There are currently about 50 registered aircraft with 3 kitfox among them and a good mix of other experimental types. 
    Sadly avids and kitfox registered abroad as ultralight are not allowed to enter swiss airspace, only experimentals can. Switzedland unfortunately has very restrictive rules for ultralights 
    If anyone is planning to come from the forum drop me a note, would love to put some faces to the names.

    Brändli Cherry BX-2
    how did brittney say.. "ups i did it again" ... almost a year after i bought my unfinished Avid Flyer Model C, and about half a year after I sold my "daily flyer" (i wish it was daily), i bough anogher airplane ..
    here is the story that led to me purchasing another airplane.. or at least that's how i found a reason to buy another one .. 
    i sold my other aircraft last summer and with it i had lost my hangar space. the airplane was bought by the flight school where i had learned to fly and i made a deal that would allow me to rent it back for a very attractive price.. as a matter of fact i would be able to fly it for about half the cost than when i owned it. the airplane was supposed to be used as a rental for touring only and not for trainig new pilots.
    however, around new year another airplane of that flight school crash landed after an engine failure. luckily nobody was hurt but the airplane was totalled. at around the same time i got an unexpected invoice for the rental of "my" hangar space. turns out, the school never informed the airport authority about the owner change of "my" aircraft. knowing, that it is extremly hard to get a new hangar space in the future (10+ years waiting lists) and suspecting, that my former aircraft will probably now be converted to a school airplane which means, it won't be available as much and it will most likely get more expensive for me to rent it due to all the extra equipment (brake upgrades, silencer, some more avionics etc.) i called the school and asked them, if they still needed "my" hangar space, as they had moved the airplane to the space of the crashed one recently.
    they responded that they did not plan to replace the crashed plane, so there i was, i suddenly had an empty hangar space and potentially a struggle to find a slot to rent my airplane back.. so the decision was made, to buy something small and cheap to operate to keep me flying whenever i wanted in the near future, at least until i finish my avid and potentially even longer.. 
    i started to look around for a cheap to buy and fly experimental aircraft, preferrably registered in switzerland. ideally it would be something different from an avid or kitfox, possibly something that covers a different mission.. a fast traveller for example.
    with a bit of luck i found exactly that within about a week of searching around the web. what was important was, that i wanted to have an airplane that was flyable as is and did not need too much extra work because i already have my avid project which is not progressing as fast as i would like due to a new member in our family ..
    the airplane i bought begining of this week is a plans built wood and composite aircraft. it is a two seater with retractable gear and it is powered by a Continental C90-8F, which means it has no electric starter! Actually even the alternator was retrofitted to the engine. with the 90 hp of the continental engine the airplane will cruise at around 130mph and carry two people with a little bit of baggage. it is fairly tight, but nothing i would not need to get used to anyway for the avid
    it has removable wings and a trailer was included in the deal, which comes in very handy right now as it is currently deregistered as the owner had stopped flying it two years ago, so it needs a fresh annual and a airworthyness check by our FOCA (like FAA). I had the engine checked for corrosion prior to buying it and it was deemed to be in good shape. one thing i want to do is replace the radio with a newer one, as we are no longer allowed to use 25khz band in europe since about a year ago, so my other option would be to fly without radio or use a handheld. no radio is not an option because of the complex airspace my home airfield is in, and a hand held will be fiddly to operate due to the same reason.
    my plans are, to actually replace the entire dashboard and only keep the transponder out of all my existing instruments and equipment.. everything else will have to go. i will then install a MGL MX1 with a hidden MGL V16 radio operated through the touchscreen of the MX1.. add to that a panel mounted tablet for my nav software and i'm all set
    so some work to do after all, but i have to wait for my Mechanic to be available for the annual anyways, so i might as well do that in the meantime.
    i've attached  a few pictures of the airplane and the current dashboard. i've hand-propped it already and still have all my body parts attached to me, not so difficult to do after all.. i'm really looking forward to flying it later this summer.. it will be my first time landing a tri-gear

  11. Pascal added a post in a topic Picture of your pedals   

    the taildragger i used to own (Jodel DR1050) came with drum brakes from the factory. the flight school where i got my PPL had those same aircraft but they put quite aggressive cleveland brakes in there. It is a never ending debate on the Jodel mailing lists weather brakes on a taildragger should be able to lock up or not.. i personally had mine tuned so i could theoretically lock the brakes and flip my airplane if i wanted.. personally i would have preferred the aggressive disk brakes we had on the school airplanes, but the conversion was so expensive, that i decided to live with the stock setup and it worked just fine.
    I think in the end it boils down to what you need in order to go to the places you want.. if you land often in super tight spots where you really need to keep your braking distance to a minimum it is probably better to risk flipping your airplane if you are doing something wrong rather than crashing into trees because your brakes didn't pull hard enough .. with the above aircraft i could land in most grass fields around here without even touching the brakes, so i really didn't need the disk brakes.
    another factor is also the weight and balance of your aircraft and the grip of your tires on the runway.. trent palmer made a video about how he lands and he stated that he often touches down with his wheels locked.. he's got enough weight behind the main wheels and not enough grip with his tires on the dirt to flip the plane.. so being able to lock your wheels does not necessarily mean you are going to flip your airplane if you land with locked brakes..

    wow it sure does look beautiful .. what is your density altitude with such cold weather? probably gets you an amazing take-off performance .. i always enjoy flying when it's around freezing temperature because the aircraft performs so well compared to a hot 100F summer day.. however. in temperatures like you have it i'd probably stay home and wait for it to warm up ... can you get your avid / fox heated to a level where the windshield does not freeze up from the inside when you breathe while flying ?

    Reinfocrements required in Switzerland
    after reading some of the information on the board here regarding the differences between the Mk IV and my Model C i realized, that some of these modifications where done to my aircraft by the previous builder already. Digging deeper into it, i found out, that in Switzerland every Avid Model C (and probably all the other Models as well) kit needed to be reinforced in order to keep the officials at our Federal Office of Civil Aviation happy.
    Over here, the first build of a new design has to undergo some additional paperwork and checks. The entire design is checked by officials who are engineers and re-calculate the structure etc. to double check that the final product will comply with national regulations and safety standards.
    From what i've heard, this process happens in a tight dialogue with the manufacturer of the kit (if the manufacturer is available for that) and results are probably also fed back to the original designer to maybe help improve the design.
    so here are the documents i got together with my avid which detail the reinforcements which are required over here on every avid flyer.
    they're all done on mine, but i think it would be interesting to hear from an avid MK iV owner, which of these points have made it into the Mk IV and which did not.. also i wonder if owners of avids without those mods have actually seen the necessity for such a mod or experienced deformation or whatever issues that would confirm these mods are actually worth while ..

  14. Pascal added a post in a topic Avid Horizontal Stab Rigging   

    no, that's something the swiss FOCA (equivalent to the FAA in the us) came up with... together with the same kind of gussets at the rear carry through, mounting brackets for the window which are welded to the carry throughs so you don't have to drill into them and some other reinforcements.. as i went through the differences between the mk IV and the model C i actually noticed, that some of these reinforcements seem to be standard on the Mk IV.
    the story behind all this is in the way experimental aircraft are built and registered in switzerland. The first bilder to build a new design, be it a kit or a plans built airplane or a one of a kind airplane has to go through quite some additional effort to have FOCA engineers verify the design by Swiss standards. It doesn't matter if this design is flying elsewhere in the world, they want to make sure it complies to our regulations for strength etc..
    when the first builder of an avid did the whole verification, the FOCA engineers found chance to prove that they are indeed needed, so they came up with some modifications to both the fuselage and also the wings (both the front and rear spars have doublers installed towards the center to reinforce them) in order to make the airplane compliant with their ideas of engineering minimas
    as a result, every avid registered in switzerland (HB- Reg) has these gussets and the other mods installed. we all had to take our fuselage out of the crate and drive it straight to a certified welder to have the mods done.
    Luckily, the previous owner took good care of doing all this and complying with all those mods.
    After discussing in another thread about an Apex installation, i went through the mods yesterday evening and thaught that i could scan and upload them to the forum.. it would be interesting to see how much of these changes made it into the MK IV.
    the FOCA is usually in direct contact with the kit manufacturer and also reports their findings and calculations back to the manufacturer..
    just to be precise.. today it is no longer the FOCA doing all this, this work has been delegated to the EAS which is the equivalent of the EAA in the us.. however, the process is still similar. We also have to get all modifications approved the same way, so stretching a fuselage is a big deal around here (for the first guy, but it is very well documented afterwards for others to follow) ..

  15. Pascal added a post in a topic Apex in a Avid C Model Thoughts   

    Hi Jack. i think money should not be the motivation to go for an Apex engine. People tend to compare a brand new airplane engine to a converted car, bike or snowmobile engine where the conversion starts off with a used engine with mostly unknown past. if you look at used 100hp rotax ULS or even overhauled ones, they are a lot more affordable than factory new ones. Stick around for long enough and you might find a good bargain that includes already some accessories like engine monitor, exhaust etc.
    if you don't like to buy a used rotax, then don't start with a used Apex or whatever engine, because that engine could have been over-revved, crashed, run out of oil etc. just like any other engine out there.. only that people tend to care more for the engine when their life depends on it (as in an airplane at some situations) and less if it's just a fun toy..
    after you factor in the cost for all the custom made parts you are going to need, the psru, engine mounts etc. you might end up with a higher price tag than a comparable rotax.
    mind you, i say all this without knowing too much about the Apex conversions available, i've just spent a lot of time looking at conversions of all sorts of engines for all sorts of aircraft that i was considering to build or at least dreamed about building in the past.
    the benefits you can get from a conversion are: better power-to-weight ratio (sometimes) or simply more power, use of a different fuel (i.e. diesel, Jet-A1, E85), sound (i.e. V8 conversions ;))
    since you have trees at each end of your runway i suppose there aren't too many spots to land in case of an engine failure during take-off.. so you might want to consider reliability of an engine as an important factor in choosing your engine . If you go with an engine like a rotax, you not only get an engine that has proven its airworthyness in thousands of airplanes with millions of flight hours accumulated, but you get also an engine for which an information channel is in place to inform users of the same engine of defects found on others that might affect you as well. there is no such thing as AD's and all that for a converted engine from some other vehicle.
    if you are on a tight budget but want to install a 4-stroke anyway, take a look at the 4-cylinder jabiru 2200. I've read on this forum that the whole insatllation weighs about the same as the rotax 582 but you get a few HP more out of it. There is even an engine mount available for the avid by jabiru which you can buy together with the engine in case you go for a new one. there are also plenty of avid model C's flying with the jabiru and every now and then one of them becomes available (or at least the engine and mounts do)..
    i'm not a rotax sales rep or anything.. these where just my thoughts as i was weighing my options for the engine i wanted to mount into my avid ..
    i may have to add, that here in switzerland we don't seem to be as free as you guys are, when ti comes to for example welding an engine mount.. here we need to have the work done by a professional welder (which i'm not), we also need to have every modification from a previously approved design checked by a certified engineer (which again, i am not) to verify the stability and what not. so for example stretching the fuselage would be a huge deal here. so in the end, for me it is also a benefit to being able to buy an engine mount that is already flying on an avid in switzerland and that's the case for both the jabiru and rotax.
