Hey gang, I was impressed with the half sheet racer that Springer made over on RCGroups.

I thought I'd take my hand at making a half sheet plane too. My plans are based off his. although there are a couple of tweaks.
I modeled my spitfire in 3dsmax to get the shape right. i dont have small electronics, so everything is bigger than what he uses in his racer. so this should be intersting. I will use my blue wonder motor i have from having built a bloody wonder, also i'll be using the small 500mah 2s battery. its much bigger than whats needed for this small plane, but hopefully its not too heavy. also the smallest esc i have is a 20A, so that'll have to do, and 9gram servos, would have prefered to use 5gram ones, but i'm wanting to build this out of parts i have already.
The plan is to build this from elmers foamboard (its like adams readiboard, but its all i can get here in montreal) with the paper removed from most of the pieces. as the paper adds a bunch of weight, i am hoping to get this as light as possible, hoping it'll be a fairly slow flyer. i plan to keep the paper on the inside of the nose cavity, so the nose will have some extra strength for when i'll likely high five the earth. also maybe keep the foam on the top side of the wings. should provide a smoother surface and a bit of strength. if i cant bend the wings enough i may just have to glue on a bbq skewer under the wing for strength. but we'll have to see how it goes.
you can get my plans here from my dropbox, I dont know how to attach a pdf to a post
