RE: plyon size engine .15?
Hi,
I have been flying a scratch built 15 size model with an OS 15 LA. It is named Wild-Pudding, and flys quite nicely. It has flown past 100Mph, and does really nice pylon type turns. It has 48 inch vacume bagged ellipical glider wings, and a simple balsa box fuse. Since it has glider wings, it really floats in for landing, and I have even done a bit of thermalling with it.
