i am having a problem getting my blades to track right on my axe cp. when i am flying my axe in normal mode it flies perfect. when i fly my axe in idle up thats when every thing gets really sketchy. it gets super bad vibrations and it jumps up and down and i have noticed that the blades are not tracking correctly. i know that all of the vibration and jumps are caused by the blades jumping in and out of track. i have tried to replicate what is happening on the ground but the blades track perfectly. does anyone know what the problem may be? by the way i have the bell-hiller rotor head upgrade but i don't think that it has any thing to do with it.
