This other demonstration is quite convincing. To tell the truth, I make the transformations in order to be able to embark my Alaskan Malamut of 48 kg and make trip in the Alps, on alti-surface for example. I'm not sure I can do it though, it will depend on her of course. I also have to make sure she can't go too far backwards, with some sort of netting for example. Its weight should be distributed on the passenger seat and a little on the back ideally where the place would be more comfortable and spacious as well.

The idea of making a plane that provides the same services as the super stol from Just aircraft and for a much lower cost really appeals to me. Otherwise, I saw pictures of Dean on Facebook. He made himself a mini Ellipste it seems. A wooden structure wing.

Randy,

27 5/16" = 69,37 cm (Yours) / versus 69,85 (Factory approximately) / versu 69,60 (Mine). The mine is better !

27 5/16" (Yours) / versus 27 1/2" (Factory approximately) / versus 27 13/32" or 27,40" (Mine)

Take your time for the photos, no rush

Hi Randy

You have convinced me ! Stretched fuselage.

Another question without forcing you. If you had to invest in a TIG, which would you choose? 

Ok for the push pull cable. 

Justine

Chris,

I was not very sure of myself for the different length of the cables, please let me know. I understand ! You know where it is possible to buy them in the USA. I have yet to hear back from cablecraft UK.

It's not supposed to have any play in the teleflexes, but hey!

Justine

Hi Chris,

Indeed, your contribution is quite relevant and I thank you for it.

I'm going to lengthen the fuselage accordingly, I hadn't planned it but it's nevertheless preferable in my opinion. I had always flown Rotax 2-strokes. My original idea when I went to retrieve this fuselage was to install an electric motor, but I'm going to give it up. Autonomy is still too low. 1 hour maximum flight.

Even by extending the tail, it is still centered forward with the 912.

The plane is stored for the moment, I can't do anything where I am. I'm also missing a lot of parts and I admit that I'm quite tempted to ask for them in Russia. They made a carbon copy of the Avid Flyer. I know that Just aircraft can make me the wing struts that are compatible, but it takes a very long time, I contacted them. https://reaa.ru/threads/stroitelstvo-klona-kitfoksa-avida-v-pavlovskom-vladimirskoj-oblasti.6876/page-2

Just for information because Marc Mendick responds to absent subscribers, so there may be an alternative in Russia. I am also looking for ease and speed.

They are based there otherwise : https://www.aero33.ru/

Hi Randy,

I understood everything well, as the photos available on the Avid mini+ thread are sufficiently explicit. I've already checked the thread and printed everything out in case we get a cut from the internet.

I was planning to reinforce the frame at the elbows after having clamped the cell on a jig and before cutting the tubes.

Your recommendation for lengthening the fuselage, in addition to better road stability, is it essential for a Rotax 912, in your opinion?

Do you have some photographic details of the modifications on the rear of the fuselage for the damped tail wheel?

So my fuselage is a Mark IV. That's what I wanted anyway. Look at this dimension however (width at the shoulders) = 1020 mm / 40.15 Inches

I take advantage of having you on the file to ask you about the distance between the hole is 27'' 1/2 (69.85 cm) which is also the distance between the two wing spars in tube d 'aluminum. This dimension is slightly lower by 2 mm (69.60) on this fuselage. Is a serious problem in your opinion? Should we try to bring it back to the norm?

At the same time, I publish photos of all the points on the fuselage that need to be reviewed.

Bien à vous,

Justine

PS:I sent a message to cable craft UK with 183-VTT-5-78

 

 

A Katalina in Canada is paradise!

I share your opinion for OFAC in any case. I wonder about the relevance of declaring it in Switzerland. Rather France, possibly. In the case of a ULM registration, but it is not the one I prefer, it does not concern the EASA. It is still the national legislations which are in force for the ultra light. That being the case, I will probably register it as an airplane because I didn't spend a fortune passing my PPL, my CPL /IR to do ULM. (MTWO and flight plan to cross borders.)

You know, by that, the OFAC delegated the monitoring of the construction to amateur builders (EAS). I met a very small fraction of these amateur builders at a monthly dinner. I noted that some of them and the most important were in the sanction, without even knowing me, as soon as I will started to tell them that parts were missing and that I first tried to find some used before considering making them myself. I know the Avid flyer pretty well, I'm very comfortable with this little plane, I had also to do instruct at Montardoise farmer. Fuselages under construction, I've seen tons of them. my first avid that i have build since is number 473 (1989).

"Vancouvert", the English-speaking provinces are known to be 100% pro aviation. This is where you have to be to fly.

you never know what life has in store for us, my trip to Canada is unlikely however, with the great war coming on top of that. Thank you for your invitation, I will open the link you sent me and I wish you a good flight in your paradise.

Cordialement, Justine

PS : Verry nice pictures !

Buddy from Just aircraft who I had also contacted for parts compatibility, just got back to me in 24 hours. I appreciate their professionalism.

The Highlander's lift strut are compatible with the Mark IV. It was, for me, the biggest difficulty since all the other parts are easier to make, but if I can refrain from having to have them made by a locksmith, I like it as much, even if I prepare the work.

Just aircraft can't produce the struts at the moment, because first of all they have to catch up on the delivery delays of their kits, they have to get a lot of orders by the way, one can imagine it and that's so much better for them.

Marc Mendik hasn't responded yet and I can understand that. I'm counting on you to say a word to him on occasion. There's no rush, I'm insulating and setting up the workshop for the winters.

There would still be a lot of work for an Avid kit maker. The demand is colossal.

I just emailed mmendick. I hope he will answer me

It is indeed possible that the fuselage has another origin than the Avid/Airdal factory.
Regardless, it's well done. The mediocre quality of the welds came after a repair, following the crash (Jabiru engine failure).

In reality, the goal had not been to repair it, but to straighten it in a summary way to make a copy, the friend told me. This is the reason why they did not take any care with the welds. I don't know yet if the fuselage is salvageable. It must be in principle, I want to believe.

They had to heat certain welding nodes with a blowtorch and also for to straighten certain parts of the fuselage. You can clearly see the burnt parts. The result however is that they annealed all those hot spots and an expert would tell me that the metal has lost its fundamental characteristics, besides corrosion. It is possible that it is necessary to seek the good quality of the tube far enough to properly anchor the upper part of the cockpit, and the wing attachments which support all the load. All the rest of the fuselage is intact so to speak and that's already good, 2/3.

I would say that an expert should give me his opinion. I also have the option of having the fuselage and all the welds x-rayed, but it is better to do it once the repair has already been carried out in a pinch. A new fuselage costs 5000 Dollars/Euros/Francs, except that it is no longer manufactured. It might be worth getting it back if the repair isn't too expensive. I can prepare the work, prepare the tubes in metric dimensions, but I will not weld them, I do not have the skills, even if I am tempted to do so.

I  plan to expected to make the same adaptations as Randy.g.tyler, except for the lengthening of the fuselage. I wanted to write to him, but no answer. The photos on the post are very explicit and I will be inspired by them, I will do the same thing.

If I can find a few used parts, (Mixer, control column, Mark IV tail, strut), I'll probably buy them to save time.

Avid Stretch (Mini Plus) - Fat Avids, Avid Plus and Airdale - AvidFoxFlyers Forums

For the landing gear, I'm thinking of this one http://www.ulmag.fr/index.php?lire=mag2/salons_aff.php&art=blois_2016&p=4&expo=019

I happen to make this kind of error. 1.2 for 1.02 or 1020 mm. You corrected me.

It was indeed the distance between the pins in case I find a pair of wings already built, even if it is better to build them yourself.

I went to measure again today and here is the result: https://myalbum.com/album/uhYhrdtJiPib

Oh God!

We're not going to complain, there's width, it's good!

I would like to be sure of the dimension between the leading edge pin and the spar pin. (The wing attaches to the fuselage)

Can you help me ?

Justine Boivent

It's really strange indeed. The dimensions in metric that I noted can help us to make a comparison. The dimension of 1.2 meters in width at the elbows. 

However, it seems that its designer is trying to improve it. The fuselage seems to have been mechanically welded at the factory.

The lower part of the fuselage is, so to speak, preserved with some details no good. The upper part where the wings are fixed must be completely redone and it is not an easy task.

If I didn't know that welded mesh steel fuselages could repair yourself quite well, I'd say this one is good for scrap. It'free !

I would like to have your opinion, the opinion of the community on a possible repair. Its relevance!

Can you also help me identify this fuselage? The structure differs from what I used to see.

All pictures are available at the following link. https://myalbum.com/album/uhYhrdtJiPib

Hello

The photos I took in the craze are not detailed enough to identify this fuselage. My friend told me that it was a kit made by Airdal, that this plane once assembled had been equipped with a Jabiru engine, that it crashed and its previous owner had bought a new fuselage and had to recover all the parts on that which I recovered, in order to assemble them on the new fuselage.

The one I recovered was redreseated more or less well, it was badly repaired, because the objective had been to make a model of it to copy it only. Square tube stiffeners have been welded inside to maintain correct geometry. I have to remove them after clamping the cell on a template.

More photos to come, I have to set up the new workshop. I will work with a summary lighting in a first time and content myself with noting the dimensional characteristics of the fuselage.

The whole point of the Avid flyer is its stol capabilities, I love this plane. I had sold mine in 1996 it seems to me and it was to finance my CPL. I'll keep the original profile and probably adapt Kitfox's twist at the time of the build process.

The forum is excellent for constructors, it is really rich in information. 

KF3 tanks in an Avid STOL/HH wing http://avidfoxflyers.com/index.php?/topic/5510-kf3-tanks-in-an-avid-stolhh-wing/#comment-48852

I'm going to pick up the fuselage this Thursday. I leave Lausanne and go to Blois-le-Breuil located in neighboring France. It promises to be folkloric when crossing the Swiss doaune with a fuselage sticking out of the van. I could take all the dimensional characteristics of the fuselage the following week to be sure of knowing which what model is it

I'm sure I can put this plane together with the support of the community. 

Justine Boivent

Thank you for your reply. Yes, indeed, you can speak to JImChuk about it if you meet him from time to time.

I had already built an avid flyer in 1989. A model B No. 473. I'm pretty easy with the wings and can indeed find the spars and make the ribs myself. The manufacture of the strut wing on the other hand is for me a bit difficult to do. The upper fixing the strut wing on the spar must be able to be found at Kitfox.

Remains the landing gear, the mixer, the control column and the sticks, the flap lever, the rudder pedals, The depth wheelhouse. The stabilizers that are not the most difficult to achieve. Only here, someone who does the work for me is probably more inclined to get involved for several pieces than for one or two. JImChuk ?

I can buy the tanks from Kitfox, the wheels and break from Spruce and I do the engine cowling myself and wing tip.

The friend who gives me the avid + / Mark IV Airdal fuselage has a second one that needs to be repaired, a model c (see tne picture add). He sells it cheap and it may be worth taking it too to cannibalize it. The question I ask myself is: is the horizontal stabilizer of the model C the same as on the Mark IV (same surface...). It does not have the struts wing however, not the landing gear also. I can just salvage the mixer and possibly the horizontal stabilizer, not much more.

The best.

Justine

Hello Avidiens,

A lot of work awaits me. I am going to undertake the assembly of an avid flyer, but this one is completely devoid of parts, I only have the fuselage.

I think about how to go about it and given the quantity of parts that must be made, knowing that it is necessary to make a template each time for the mechanically welded parts, I think it would be in my interest to arrange with the owner of the welding jig located in the USA.

I would appreciate it if anyone can put me in touch with the right person who can do the job for me.

My project will not be profitable if I have to make all the jigs, buy a TIG and buy steel.

I am located in Switzerland

Many thanks

Justine

I don't believe it's an Avid Magnum. It seems to me that the Magnum mixer is drawn differently. Remember, we could place 2 young children in the luggage compartment. 

Also, the friend just replied to me. He tells me that it's an Avid+, that the fuselage is damaged and that it has been repaired in a hurry to make plans.

I don't know who initiated the Avid Magnum, but I know that the friend in question knew the French importer of avid Flyer (Hubert Ferté) well and that he did not hesitate to make repairs in the workshop . He had to recover this fuselage from the importer (Euro Fly Aéro). It is this gentleman importer in particular, who had financed the development of the Ellipse, would he have participated in the development of the Avid Magnum? The one you have on the photo must be the first Magnum of France and maybe alone , it is n°07.

The friend tells me that it is an Avid +, it can be recorded in Kitplane or in Ultra light. I will pick it up shortly in the Loire, from Lausanne where I live. I will take pictures and post them on the forum. I don't know yet how fast I will progress to restore it to flying condition. I don't have enough to make the wings yet. I also have to redo the main gear.

Stay tuned and thank you for your insight.

Your information regarding the technical data of the Magnum is very helpful.

On this video there is magnum structure to show https://youtu.be/RxaulYBYkI4 and https://youtu.be/tnzzfinaQhE

Indeed, it is exact for the impact loads of the main landing gear, it is rather good! However, I hope it is a mark IV at least. They are longer than the model c I think. I'm going to send the link to the thread to my friend, he may be able to tell us.

I put the link with the photos of his Avid magnum that he has since sold, just so that you can locate the place where the fuselage in question is. http://tagazous.free.fr/affichage2.php?img=9256

Unfortunately, I only have this one. The boyfriend is not very motivated at the moment. It is clear that the tube should not be welded in this direction. It's a big riddle, thank you all the same for your interest.

There is the triangular plate for the VHF antenna which can be an indicator eventually

I am still looking for information regarding a fuselage that is offered for sale. An old friend put it up for sale and introduced it to me as an Avid flyer Mark IV made by Airdal. It seems to me that he had mentioned the Avid + model.
I was well informed on the forum, in particular to find the dimensional characteristics there. This forum is really awesome by the way.
However, the fuselage that I show in the photo does not look like the Avid + Airdal, it looks like it does not look like any other, given the direction in which the tube that I have arrowed has been welded. It's not even mechanical in terms of constraint.

Can anyone help me identify this fuselage? Thanks

I asked the question on the Avid flyer forum on facebook and someone gave me the answer. So I mention it here.

It is a stretched version of the Mark IV, when it was marketed by Airdal. This was to meet the need to install heavier Rotax 4-strokes. The plane was too centered at the rear if we were content to install a 2-stroke and I experienced this at Montardoise. He stalled suddenly at the time of the flare. A detail that could be corrected provided you place weight in the front.

https://hyperleap.com/topic/Avid_Aircraft/Avid_Flyer

I can't confirm anything yet, I saw a topic about  this subject on this forum, certainly much more instructive.

https://www.planeandpilotmag.com/article/airdale-flyer-company-avid-flyer-avid-magnum-mark-iv/

After, may be they are another modifications, but I don't know exactly.

Does anyone know the Avid-Flyer "+" or "plus" version?
How can it differ from the Mark IV?

thanks for your help
