When I was building my KR2SS knowing that I was going to hang the larger engine on the front (O-200), I put another 1/2 degree down on the leading edge of the horizontal stabilizer. It was not enough. With no trim, You have to hold back on the stick. It's bad enough that if you were to release back pressure, It would dive hard for the ground. This seems to be an issue with some KR's here on the net. With trim adjusted, she flies like a dream. Looking back, I wish that I could have designed a horizontal stabilizer that you could adjust for trim while in flight. There are several certified aircraft that have this but the design is a bit heavy for the tail of a KR. I know that Mark L. and his N56ML, had a ground adjustable that he designed with no weight penalty. If I were building today, I'd copy Mark on this too. As for my trim system, I decided to keep it internal with nothing on the outside of the airplane. I ended up using a 6 inch linear actuator and a bungy cord hooked to the elevator bell crank. After several adjustments on the bungy diameter and length, I found the perfect combination. I can fly hands off at any speed. That being said, Just keep building, These little pocket rockets are a hoot to fly.
