Default Adjusting servos; Spur gear sliding on shaft, reducing lift

Hi all!,

So, this is my first CP and after hours on the simulator I took it outside today for the first time. When I have the ailerons trimmed out all the way to the left the heli is about level, but doesn't bank left nearly as hard as it does right. I'm assuming I need to adjust a servo? I think I have something similar going on with my collective forward as well...

Also, when I crash (I'm the grass usually) either the spur slides so far down the shaft it disengages - or it stays engaged but with a lot of slop on the shaft which is killing my lift. Is there a fix for this? Maybe a steel gear with a set screw? The other thing about the gear is that it's now warped which I'm sure isn't helping with vibration and run time.

Any support would be greatly appreciated!

Thanks in advance,

What you're seeing with the main gear when you crash is pretty much normal. It's a simple press fit so it will give when you crash. If it didn't then something else would. Just press it back on until there is no slop and fly again. It will eventually get to the point where you'll have to replace it.

As for the other issue try recalibrating the Gyro's. There is instructions in the manual on how to do it. If that doesn't help you'll need to adjust the servo links to get the swash level.

Remove trim from the tx. Not good with flybarless helis. The flight controller sees it as input.
