I have a TRex 450 and 600 with Futaba 9CH reciever on the 600 and Berg 7P on the 450. Lately--especially with the 600 the heli will fly off out of control with no response to control input right after takeoff. If I can save it then the heli will fly normal after I take off again, but I have had some serious blade strikes (ie destroyed). Also the 600 will often "pulse" when I cut the throttle--rev up and down with out really stopping. I have fooled around with the throttle trim and subtrim to no avail. Anybody have any thoughts on that. Seems like it must be something with my radio if it does it with both helis??
