tmalone is right - you do not need more power. I built mine and hung a OS .15LA on it because i had it laying around - what a crazy five minutes of my life that was......sheesh. I hand launched it WOT and was lucky I didn't run out of radio range before getting my fingers on the gimbals...The MT went straight vert FAST. After throttling back I was able to do a few passes and started pulling some tricks, but the temptation is too great to open that throttle. Back at WOT i put that poor little plane through hell for a good couple of minutes before half of the elevator folded and started flapping around (held on strictly by the covering) - what a noise...... Alas, she met the maker.

I had added alot of stiffening and structural to the plane all over it to compensate for the extra power and weight of the .15, but the elevator (horizontal stab)was the weak link. Pretty near all that was left of the plane were the areas where I had strengthened or sheeted. I had also extended the wings by one extra rib bay on each end. Going to try this scratch build again starting next week, this time with a supertigre 370 brushless.
