Average Reviews:
(More customer reviews)I bought this replacement rotor/parts pack for the Black Ghost chopper because I had broken off one of the helicopter blades after colliding with a ceiling fan. The helicopter still flew with only 7 blades!!! But it wasnt flying too well in that condition so I got the parts pack.
The replacement rotor was pretty easy to install. No tools are needed, you simply pull the rotor assembly off the shaft with careful pressure and put on the replacement. The replacement parts pack also comes with blade spacers and tail rotors, making the package very comprehensive.
One thing I did notice however was that the replacement rotor assembly was of a slightly different design than the rotor that came with the helicopter. After replacing only the bottom rotor assembly (and reusing the original top rotor), the helicopter had spin/torque issues that the trim control couldn't solve. Eventually I realized that this was because the replacement rotor had a lighter/thinner rail that circles the tips of the rotors, and this caused uneven torque effects, bringing the contra-rotating rotors out of balance and making the chopper spin. To fix this issue, I had to replace the non-broken original top rotor with the replacement rotor as well, and this solved the torque/spin problem. Now the helicopter flies straight and true again, and no trim is necessary!
Overall I was very satisfied with the replacement parts kit. Just be sure to pay close attention to the differences in the replacement parts and the original parts, cause if you only replace one of the rotor assemblies, you might encounter spin/torque effects that the trim can't solve. If this happens, simply replace the other original rotor with the replacement rotor as well and your problem will be solved.
