But there were talking about sides skins to be laminated. For me here is clear, I will do as Eduardo Barros from Argentina. I would like to ask your opinion about composite sheet which is used for Printed Circuit Board, of course without cooper. This kind of material I am planning to use just on the spars. Why not plywood, I simple can not obtain it here (aircraft grade) and I would like to avoid using of plywood. But I have this PCB sheet in 2mm thickness, it has about 10 layers of laminated fibers which is pressed together and cooked. Compared with plywood it is much stronger, although there could be some weight penalty (just a little), which is not significant. Any idea? I hope you will understand my question, sorry for my English. BR, Alex ------------------------------ Date: Tue, 19 Aug 2003 09:05:47 +0100 From: "Serge F.

First, she is no longer a retract. I have just completed the conversion = over to the fuselage mounted spring gear with hydraulic disc brakes. I = have filled the holes in the wings and flaring in the gear to the bottom = of the fuselage. I am now re designing the tail wheel and rake of the tail spring. I have rebuilt the engine, and changed the carb to a updraft Zenith,and = a 009 dist. with a high output coil. I have a starter and acc. case but no longer using a mag. I have changed the alternator to a Kubota 14 amp. dynamo and a Harley = Davidson 14amp. regulator. That is belt driven off the flywheel end of = the crank. I used a standard gland nut with the bearing removed,milled out to a = 5/8" hole, and welded a shaft to it and matched a pulley to it from a = old alt. I have also solved my aileron problem by carving out holes in the wings = and ailerons , drilling threw each rivet,and installing a ss screw and = nutplate(to the back of the false spar) then floxing in the nutplate and = filling the holes.=20 I am hopping to have her painted and reassembled by the end of = September.

In fact it is a Fiberglas, just difference is in that the fiberglass layers are pressed and cooked at high temperature vs ours wing skins are not pressed and normally cure at room temperature. I am not from Argentina, I just mentioned Eduardo Barros site. BR, Alex Birca Moldova Alex, I am sure that it is strong, but I am concerned that it would be brittle and under stress could crack.
