Help! I've just purchased a honeybee cp2 Ive charged the batteries etc turned on the helicopter and started to increase the rpm the main head starts to turn put past about 1/4 power the head speed does not increase even if i put the power up to 100% still no increase i also noticed that the green led on the gyro unit turns from green to red. if i input a right turn the head speeds up! take the input out it slows down there dosen't apear to be any restictions in the movement of the head and all the servos work as they should if any one can help please do cause i'm stuck!

Are you using the radio that came with the helicopter? Sounds like you may have CCPM mixing issue.

First check that the motors are plugged into the right spots on the 4in1 unit one is for the tail motor the other is the main motor...

I definately agree with slider on this one...it sounds like the two motors are reversed on the 4in1. I don't remember which motor goes where at the moment, but if you just swap them that should do it.

Ok, so swap back if you haven't already.

Ok, so how about we get this thing going? Although it's possible that the pack could be bad, I think it's not very probable as I haven't seen a post on here like that before. Question for you...when you give right stick it speeds up, but what about left? Also, is that rudder you're giving or ailron when the head speeds up? Since it's not a motor reversal, I'd say that it's ccpm interaction. Are you using the stock radio?

shuff13,

Have you checked the "Servo reversing" switches on the front of the tx? I don't have a CP2 but had a Blade CP and the switches are setup
down,up,down,up (from left to right). YOu might check the manual and see for sure...good luck!

What goes up must come around

The light on the 4-in-1 changing from green to red indicates that the ESC is running at full - If you're using a computer radio you can unplug the motors and adjust the throttle channel travel down until the light doesn't turn red until full stick - Otherwise it's good to run at full throttle nearly all the time anyways -

If this is a computer radio (you haven't said what radio you're using) there could be a rudder to throttle mix enabled - But maybe the 4-in-1 is funky and has the mixing opposite with rudder to throttle instead of throttle to rudder?

Also check that the rudder channel is operating the correct direction - Right rudder should increase tail rpm and left rudder should decrease tail rpm - Also make sure the tail motor is turning the blades the correct direction.

Hey folfs problem solved and it was a very simple one at that after a very close inspection of the head to check the pitch i noticed that the head would spin and the drive gear was stationary i looked at the pin that holds the rotating part of the head to the shaft and low and behold it had snapped! just goes to show that the simplest things can cause the biggest problems thanks to all that have tried to help! now for a bit of rotortuning and probably a bit of crashing lol!
