I would like to know the answer to that question myself. Todd

The blades are high quality, but they seem to be too heavy for these helicopters. The brushless moters and speed contollers seem to work, but the regular motors seem to overload. I am still playing with mine to see if there are any mechanical problems caused by the blade weight. It seems to make the torque shaft gear to the tail rotor a very likely failure point. If the tail rotor touches anything at any rotor speed the gear strips.

Not without major modification. The root is to thick to fit the blade grip, and this blade is longer and wider.

140mm seems like very long for tail blades :D

Yes they are main blades, and they are great except for the slightly undersized screw hole which required a very simple modification.

These are main blades, definitely not for the tail.
