I HAVE A KYOSHO CAP 232 WHICH IS A 40 SIZE AEROBATIC AIRPLANE, AND I PUT A THUNDER TIGER .61 IN IT. I USED THIS ENGINE FOR BALANCE MORE THAN FOR POWER. BY DOING THIS I DID NOT HAVE TO ADD NOSE WEIGHT TO BALANCE. SO THE ENGINE WAS A TRADE OFF FOR DEAD WEIGHT. NOW I USE LOTS OF THROTTLE MANAGMENT AND FLYING IS MORE FUN. I FOUND THAT THESE AEROBATIC PLANES ARE SENSATIVE TO BALANCE WEIGHT AND CONTROL THROWS. IF YOUR PLANE IS SNAPPING OUT OF A LOOP AT THE BOTTOM, CHECK BALANCE OR REDUCE THE CONTROL THROWS. ONCE I GOT MY CAP SET UP AND TRIMMED OUT PROPERLY, THE PLANE FLEW AS IF IT WAS ON RAILS. I REALLY LIKE THE PLANE NOW.

GOOD LUCK
