just finished my pizazz. it has a tt 46 pro w/ macs pipe.[not enough engine] when i took off w/ the elevator neutral. the plane went almost straight up.[not good] after alot of down trim i got it flying better but when i go to full throttle it climbs fast. i added a little downthrust to the engine but i`m not sure ifit made much difference. how much downthrust should i need ? the instructions didn`t even mention downthrust. the ins. said cg should be 3 1/4 to 3 3/4 inches. i balanced it at 3 3/4 to 4 inches. i like them a little tail heavy. it took 3 oz. of weight up front to balance. a saito 72 would be perfect for this plane i think. i`m afraid to try to fly it again until i hear from you guys on here. i know you will help me, you guys always do ! thanks alot ,
