Status: offline 		I saw a pic in one of the jet posts how someone built a f15 kit out of depron. I got to thinking about using wal mart foam core board($2.50 a sheet).
I started a couple nights ago. this stuff is amazingly strong, so no inner supports are needed. once she's finished I'm going to fill in all the cracks with spackle and sand her down. so far I'm pretty impressed with the strength and light weight. so far she weighs 7 oz. I expect she'll be around 11oz when finished which is fine for the brushless pusher prop set up I plan to use. auw should come in around 35oz with a mega 16/15/3 and 3s3p lithium pack.
any of you guys build with this stuff? if not you should give it a try.
will post more pics as I go
p.s. the nose will go on last I plan to make it out of either eps or epp foam, this way in the event of a crash it should hopefully be the only part with major damage


*update* now finished

Status: offline 		for the wing I have one balsa spar along the leading edge, once they arrive in the mail I'll have one carbon fiber spar along the cg of both wings which will also connect the two. As for stringers in the fuselage, there are none. the plane being built with this board is stronger then balsa and I don't really see the need. the aft end has support boxes for the tailerons. I was thinking maybe a few bulk heads once I strart to build the hatch on the underside, and have the battery placement all figured out.but that's going to be about it.

Status: offline 		I don't use plans. I go off photos that I print from the net and try to keep it as scale as possible. Its not too tuff really. plans are for people in love with balsa and those perfectly scale models. I'm sure I'll be one of those people some day but right now as long as it looks good and flys fast then I'm happy
here's some new photos
