Default P38- Prototype

Thanks to all for your kind words!!

Here is the spec - 1/7th scale, 88 inch span. Don't know weight yet but I think it will be around 15-20 lb range, its a big range because I have no idea which engines will fly it. I don't want to be under powered but I am looking at a pair of G26 as they are reliable and hear very good things with them, plus no ignition battery to worry about. A pair of Webra 120s will fit entirely inside and give the most power but that will require larger gas tanks and plenty mess to clean up.

Everything is scale as best I could. Lots of premolds were built prior to the main mold to accomodate the step down for cowl, gear doors and certain access panels... this is what took the longest. Probably could have easly built three of these from sticks in about the same amount of time. But it sure is less time now to build one

Robart is bigger, based on the Ziroli design and a good flyer at that. That would be the ultimate composite P38, hope to get good flying on the one I have and get the Robart later on.

I joined the two halves together using chopped glass, cabosil and resin, its pretty strong, stronger than other places that has no joint... I do have access in the front cowling area and I did not want to cut up my molds any more than I had to and I can figure out exactly where I will need it, YUP! access holes makes laying up a lot easier. By the way, I cnc cut my horizontal stab and sandwhich it between the mold... man it is strong in this area.

Sung, Ray and Henry - I'll bring one over for show and tell.

Lenny, in about a week, I will make some more specs on the gear - I am sure it will be as nice as the spit gear!

See next thread....
