MAIN ROTOR TURNS BUT HELICOPTER DOES NOT TAKE OFF
Solution 1 – This sometimes happens if your rotor blades are flying at too low or too shallow an angle.
The helicopter will sometimes take off but appears to have too little power to climb. This is nearly
always because one main blade is flying too low. If you can see which blade is flying low, follow the
same procedure as outlined in Solution 4 on the previous page. Alternatively, increase the angle on
both main blade tips as outlined in Solution 4.
Solution 2 – Main motor needs to be loosened because the main gear/motor pinion gear mesh is too
tight. The motor is retained by 2 screws. Slacken off both screws. Push the motor away from the
main gear and retighten the screws in the new position.
