e-E-Flite Blade CP CX 400-3D > Blade 400 3D What could be the Problem?

The last two times I tried to go inverted, my heli (Blade 400) dumps hard to the left and I was not able to recover either time. I would think that I was inputting right side roll accidentally, but on the sim I've never had an issue. Also, I was very high and not able to recover either time.

I don't believe that it is in the set up. What else could it be? Just as I went inverted I input full negative pitch, which I know is a problem and have corrected that, but it still doesn't explain why it dumps to the left (my left, helis right). Can a pitch control rod pop off and cause the right side roll with hard inputs? Has anyone else had a similar problem?

Thanks for any help.

Steven

Shhh, don't tell the wife.

Is your swash plate mechanically centered? i.e., when it's level, are the servo arms also level? The servo horns should look like mirror images. If they're not, you will be mixing unwanted cyclic into your collective.

umm, you do have your throttle hold set up right? how much do you know about setting up the head? starting with the servos at 90 then the swash must be level and all the arms should be at 90 degrees then the blades should be at 0 pitch. make sure the swash goes the same ammount up and down.

oh I know what could make it pitch to one side also, it could very esialy be the travel adjust make sure the travel adjust + is the same for all three servos and make sure the - is also the same.
