XK K 124 tail keeps spinning

[Azir]

Hello. I changed the "received set" on my K 124 because the original got damaged in a crash. Now the helicopter will not take off and keeps spinning! Plenty of power but the tail rotor does not spin fast enough to provide enough thrust to keep the helicopter from spinning. I have calibrated the Gyro with no result. Please help. Thank you.

Did you change the tail blade? is it on reversed?

[Azir]

Yes, I’ve double checked the blade for rotation, it looks good

[thebirdman]

Is the tail blade on backwards? not rotation direction

[Azir]

Yes, checked that as well, all appears well, the propeller spins but not with much speed, hence it does not generate enough thrust. I’m guessing that there is a problem with the new receiver, but I have no way to check.

Problem solved, bough another receiver set and tail motor cable, all of a sudden the tail rotor is spinning with full power! One of these components was defective not sure which one.
