Thanks for the nice replys,nice that you like my version of the Volmer VJ22.

The model is built up completley from 3mm Depron and a few parts from balsa, lite ply, some CFK stuff and a bit of 6mm Depron.

Step by step building photos are in an additional PDF to free download. The file is called "Weitere Baustufenfotos" and contains 13 pages A4 with 8 photos each.

The wing is made from one piece 3mm Depron, bended over the nose. Rips and spar is 3mm Depron. Each wing has two aditional ribs from balsa and the stut mounts from 1mm ply. After servo install, the wing can be closed. Then the underside at the wingtip can also be closed with a part of 3mm Depron.

to be continued, tell me if your interested

a very nice design effort, there. I have been wanting to do something very similar for a while, but want to do a Thurston Teal, instead. The design concepts will work perfectly on the Teal.

Thanks for the nudge...

Next the fus sides are prepared, positons of bulkheads and base drawn to the sideparts. First glued to the bulkheads below the plybraces. Then to the front and back. Next the bottom behind the step and upper front of the fus are closed.

Hey Jürgen,

Wonderful Plane. I really like this one and definitely want to build one. I have a couple questions for you if you don't mind.

I have never built a plane from Depron before and noticed the curvature of the wing and wing tip. How did you do that?

How did you vacuum form the plastic around foam without it melting?

I have no problem buying the magazine with the instructions to this however, I have no knowledge of the German language. Do you plan to translate the instructions in English for those of us that are not bilingual or is there a way we can work something out so that I can build and enjoy one of these?

Is there a kit version so we don't have to mess with vacuum forming and all the cutting and just enjoy the build? If not, have you considered making kits to sell for those of us less talented, capable or patient?

Did you cut each part by hand or did you use a machine to cut them out?

Sorry for all the questions, I am just very interested in building this plane.

Thanks in advance,
Orion

Orion,

no trouble about any question

Nice that you like this model of the Volmer VJ22, but no, there is kit version and I do not plan to do one. I think that it is not very hard to build, because I kept the construction strait forward. The step by step building you can see on the additional photos in the PDF. No really need in the magacine, if you can`t read it. There are no more photos from building in and give the words to an online translator, I think will give no good results:-)
The plastic parts, like canopy and side windows are made without vacuumforming. You can make this parts very easy and without any hightech machines. Just have a closer look to your oven, protective gloves
........styrofoam,..... I give an idea later, it´s late in the night right now in Germany and I just wanted to do a short answer.
Depron parts are all cut by hand, using a sharp hobbyknife, or cutter.
Bending Depron, curving is also easy to do, if you practise on som scrap material.
I think that there will be no worry for you in building a model, if you don`t loose your patience with the new material Depron.
I will tell you more about soon.........

Thank you for your reply. I look forward to more details.

I didn't see a recommended CG, locations for the ESC, RX or Lipo, water proofing if any or the size wheels that you used.

I do enjoy the looks of this plane and I have tons of extra motors, escs and servos. My buddy and I are thinking about building a pair of these. Looks like an absolute fun plane to build and fly so I look forward to your help and thank you for taking the time to design this plane and your generosity to share it with us.
