im still not convinced my blade mcpx can fly upside down. I can fly my trex 600, 450, and 250 upside down in a hover and around but this mcpx will not do it. Every time I flip this helicopter over the tail just wont stay still. It always ends up on the ground and then I more than likely end up replacing one or both of the pushrods to the blades that always pop off.
Have you measured the pitch in neative and postive? Stock mine had WAYtoo much negative pitch until I adjusted all three pushrods out by 2 turns..
Too much negative pitch and you are probably bogging down the motor and the rotor drag would be too much for the tail rotor and it blows out..
What radio are you using?
