Dears,

I'm having a weird problem with my N9, I flew 4 great flights and on the fifth when I was trying to do inverted the heli acted weird, when I give elevator it flips back but also turn right as if I was giving elevator and aileron, so I tried some forward flight and its the same when giving forward it also turns right as if there's some kind of mix or something, I don't know what is that, can anybody help?

Setup:
Synergy N9 with OS90
JR 8717 servos
GY611
MultiGove Pro
RPM 1900 IDLE2

Do you have any mixes in your transmitter?

Are your paddles aligned right?

How tight is your stick tension? This will help with the human factor by giving an input you did not wish.

Have you checked the swashes full range from top to bottom on the bench to look for interaction?

How are the servos you are running? New,old,crashes?

These are the types of things you need to be looking for.

Some pics of your mechanical set up will help also.

Thanks,
Chris

I've seen identical problem on a T-Rex.

Turned out the swashplate had dropped so low that the mixer base had come free of the pins in the head block and rotated about 30 degrees.

The swashplate pins are in their place and the swash is working good

I checked my transmitter and found no mixes

The paddles are aligned

About the stick tension, there was four flights before having the error so I don't think this could be the reason

The servos are working fine, not a single crash before

Do you think the grips bearings could be the reason?

What would lead you to believe it's the bearings in the grips?

Have you completely inspected the head? What grips are you running?

If you can post a couple pics of your set up with everything turned on and the swash at the bottom, certer, and top of travel.

Thanks,
Chris

The problem is resolved, I went to te field yesturday and found out that the heli was normal, I even tried some 3D and the it was flying great!!!

All I did was that I charged my duralite 4300mah batttery (it took 1973mah) and I deactivated the hovering pitch.
