Trouble with Micro heli... Need your help please

[bcane98]

My friend bought a heli from a LHS that is similar to the Blade CX except it's a Graupner Micro 47G V06 Bell. Well I have done some troubleshooting before on my BCX, so I did the same to find out why the bottom blade spins before the top blade and it wants to turn to the left.

This is what I have done:

1. Stick all the way to the left, then slowly added throttle... bottom blade spins first then top blade started to spin about 5 clicks up

2. Stick all the way to the right, then slowly added throttle... bottom blade spins first then top blade started to spin about 5 clicks up

3. Turned the proportional all the way to the right... trimmed to the right. no change... then all the way to the left. no change

4. I added gain and reduced gain... no changes.

5. Swapped motors connections on the 4-n-1... top blade spun first then bottom blade. This leads me to believe it's the 4n1 unit...

I would like to help my buddy out as he likes the helicopter, but is becoming disappointed at his first experience. Too bad he didn't listen to me about getting a BCX. Does anyone have any suggestions?

On my esky lama, the top blades always spin before the bottom ones. It flies fine though!

Both my BCX blades start to spin about the same time, but this chopper I don't know about. The bottom one starts to spin, I give more throttle, then the top will start. Once I get some throttle into it, the chopper wants to turn to the left even when I put full yaw to the right with trim and propo full right as well. That's what leads me to believe it might be the 4n1, but I do not know enough about helicopters to say whether or not it is. :dontknow
