Post subject: CCW spin |
 |
|
I crashed my Ufly yesterday, and broke the stabilizer bar, and both blades. I changed the bar and both blades, and fired it up. Now the heli spins counterclockwise no matter how much counter I give it on the rudder stick (happens both on the ground and after lift off). The tail rotor blades change pitch in both directions as I move the rudder control, and the blades spin in proportion to the main blades It appears). Do you have any idea what the problem would be. I would really like to get flying again.
Thanks if you can help.

Hi skyjacker,
Only thing I can think of is that it only looks as if the tail blades are in sync with the main blades.
You say they spin and move correctly with the rudder stick, but the heli is turning with the torque of the main rotors' drive. That can only be caused by reduced power on the tail rotor.
Check that the drive is correctly adjusted, (see the manual). If you try to turn the tail gently by hand, you should have a positive resistance when holding the main blades. There should be no sign of slip. If the drive is correctly adjusted, then check the drive gears. One gear (if not two) is slipping somewhere on its shaft.
Tom.

Thanks for the answer, I will do as you suggested and check all the gears. |
