I have this gyro (Esky EK02-0704B and HK401B) and both don't work. Led keeps flashing when connected wich means that there is no signal from the transmitter. But the gyro with the transmitter hk gt-2 works. Saw on Youtube that they do work with the Traxxas transmitter. I have 2.4ghz transmitter 2238 2Ch. Please help me with this problem, thanks.
