This is true of some of the cheap electrics. However I have put a on board telemetry sensor on my Lados and have never recorded that much draw. 1.5 amps is the most I have ever recorded and that was for a spike just before they shot down due to a stall causd by a bent strut. The Lados and the down and Locked ones shut down when they since excessive amp draw caused by any binding. They also extend to the down and locked position when low voltage is detected. When I say low voltage I mean a voltage above the save level for the receiver but one tha could be a concern to the safety of the model. I will be running a lithem ion 11volt flight pack with voltage regulator as I do on all my models. It is capable of pretty high current draw.
