| I built my Trex 600 NSP couple of weeks ago...
I was surprised coz the gears were so smooth and silents...
The last weekend I noticed the gears became very noise...
I checked everything, remove the tail, clean all the gears, check the tail torque tube, main gears, pinion, etc... Everithing is smooth and there's no friction at all...
I tried removing the tail and when I spun the rotor head, there were no noise. When I spun the rotor tail (not assemled), the gears made a nromal small noise.
When I assembled the tail into the heli, the noise became louder. I checked the backlash between the pinion and the main gear and it's ok!!
Just I want to know if anybody who fly the 600N have this kind of issue? Is this noise normal? |
