Simple idea?

Anyone tried making a Simple 400 fuse out of 1/16" balsa and the covering it with .75 oz glass yet? I was thinking of using triangle stock and really rounding down the sides. I already started cutting 1/2" off at the tail, and angling it back to the main fuse(from the bottom)..Looks a lot better when it tapers to the back, instead of being 1" all the way back and square. What about tryng to thin the wing for more speed?

I used 1/16" (1,5mm)balsa for the whole fuselage without glassing for my pylonracer. I also used 7 x 7 mm triangular stock in front of the wing, 5 x 2 mm after.
See: http://home.planet.nl/~raven274/pylonracereng.html
No real problems untill sofar. Only one little crack at the underside due to a rough landing. I think mine lands faster than a simple 400. Mine is 16 oz( to heavy I know ) with about 8 square dm of wing area. The wing is 8,5% thick

Jensst built a highly rounded fuselage as did a couple of others. I have read that even others glassed theirs.

My own partially glassed fuse chatterd regardless. I have no doubt it adds durability but the triangle stock may be the easiest method.

I have not sanded the wing but did try a wing from an SSP 400. This thinner wing did NOT seem to improve speed much.

Please do let us know how yours turns out
