hey guys I have a blade cx that has been parked for a long time,now tryied it a few days ago and have no control over it.Change the transmitter is there something I have to to get it to work?
thanks Fred

Hi Fred, when you say no controil your going to have to be a bit clearer mate. Do you have spinning round issues or left to right fore and aft issues etc, would help a lot and narrow things down so we can help you out

hi was turn the nose to the right,changed both motors now nose turns to the left,could it be a bad motor or something other?both motors are new now.
thanks Fred

No that sounds like your pot trimming on your 3 in 1 controller or binding gears ( one motor is tighter than the other ) the resaon for the turning is that one set of blades are turning quicker than the others producing more turning power.

To adjust the 3 in 1 to compensate simply spin up the blade and determine which way it spins ie anti-clockwise or clock wise. Do this with canopy off as it has no effect and makes adjustments much quicker

Now look at the 3 in 1 unit, you ill see two potentiometers, one with gain written underneath, the one on the right with proportional written undeneath. You need to adjust the one that says proportional.

Using a small flat bladedscrewdriver adjust the potentiometer the opposite way from the way the choppers turning ie if its turning ati-clockwise adjust clockwise.

Only adjust by tiny ammount if you can see it physically move its too much. Once you have applied this tiny adjustment then disconnect cx battery and reconnect. If you dont your adjustment wont be seen. Try the heli again. If its slightly better then repeat process again, if its worse then adjust the other way to the way you went.

This should only need doing once, once you have it right then you should never need to adjust it again

hi that sounds good I will try that.
thanks Fred

coyote64 hey I think my 4n1 may be bad because it only comes off the ground about 8" or 9 " with a new battery fully charged.
