I decided to go racing today, to avoid a frequency conflict I installed my Spektrum DSM receiver in place of the AE 27 Mhz radio.

First, when binding the receiver, I chose neutral and straight steering as my failsafe mode. I tested it by holding half throttle and the wheels turned to the side, then turned off the transmitter. In a moment the wheels straightend but the motor continued on non-stop. I rebound 5 or 10 times, always with the same result.

The next problem is with the ESC; when I turn on the radio, there is no throttle. I turn off the receiver/ESC, hold the set button down and power up the car. In a second the receiver binds to the transmitter and the motor runs, in the reverse mode. I turn off the car, power it up and now it works in brake only mode. If I turn off the radio system and turn it on again, there is no throttle. The only way the throttle works is to hold the set button while turning on the system.

Another "symptom" is holding the set button down to set the ESC to the throttle trigger endpoints; the instructions say to hold the set button down for at least 3 seconds to go into the setup mode. I held it 30 seconds and it never goes into setup.

When I had the AE radio in the car the setup, and the throttle for that matter, always worked OK.

What is the deal with the Spectrum radio and the AE XPS Micro ESC??
