Pascal added a topic in For Sale and wanted, you got it, I want itTrig TT31 Mode-S Transponder with ADS-B Out capabilityi'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)

Pascal added a topic in Avid Flyer General HangarI bought an "original" 912 MountHi guys. i am in the market for a 912 mount ever since i bought my unfinished avid Model C over a year ago.by 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.

Pascal added a topic in Local Fly in's2020/07/31 - 08/02 Switzerland EAS Fly-InFor 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.

Pascal added a topic in "other aircraft your working on"Brändli Cherry BX-2how 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

Pascal added a topic in Avid Flyer General HangarReinfocrements required in Switzerlandafter 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 ..
