This looks a little unrealistic. Your platform looks VERY difficult to repair, you will not be able to make 100 takeoffs and 100 landings in 4 days as sometimes required during duning due to engine delays... Get yourself a styrofoam platform and once the autopilot flies on smaller one, switch to larger!

Yes, you are right
This is the first airframe for testing, then we will make it with fiberglass.
this airframe is for check the measures and the firsts fligth tests.

It may be difficult to repair, but the structure looks like it would be very strong. It reminds me of the structure of a bridge. At the very least, you will learn something from it. Good luck to you.

If the plane crashes I need that the structure absorve as much energy as it can, no matters if nothing remains, the payload is very expensive, the airframe is cheap.

@Martin: that is exactly what the automobile industry does to protect the human payload.

I think your airframe is not cheap to repair in terms of repair time, compared to mass-produced EPP planes. This is why I made a remark initially.

Do you have drawings you could share?
Comment by Martin Bellomo on November 4, 2010 at 1:26pm
as soon as I have all the final plans and construction procedures will be sharing all the information

I like it. It looks like you used autocad or equivelent to laser cut this on cnc, is that right? In that case it is not so labor intense or expensive providing you have access to the manufacturing equipment. The design looks robust enough to do what you want. Also this type of airframe should be very durable.

Good luck martin your build sounds complex in size but youll get it right
