I save the 3D for foamys and profile planes. My gas planes are used 98% for precision. My elevator and rudder is about where yours is I goto high rate rudder for hammers. I think a lot of my problem is that My ailerons are too low(15 deg)..I made a high rate aileron for the snap 35deg but i think it was too much i just dropped it to around 25 deg and will try than next time i fly. My snaps look good straight and level. manuever one in the sportsman sequence it 1/2 cuban 8 1/2 roll on entry push to 5/8 inside loop 1 positive snap on the 45 degree downline. I think i have three problems. #1. I am droping to idle on the down line i think i need 1/4 throttle to keep more momentum(my snaps is sometimes teally big). #2 I think my aileron rates ar a little too low #3 The idea of burying the sticks on a downline is scary.My but puckers 1/2 second before my thumbs bury the sticks.
