does the rear prop move my heli foward? it seems to be because i have a 3 channel heli the rear prop moves when i move the right stick foward so since this is a 9101 29 inch double horse people have told me to heat the rear prop and change the pitch to be more agressive, which i did but i dont really see the heli going any faster foward?? should i change the pitch so the blades are flat? but mainly i am asking which prop moves a 3 channel heli foward, details please and which way do i change the pitch on the rear prop( if thats the prop thats moves it foward) thanks all
