I bought a RA-31 receiver for the new MA-020 Sports AWD, to replace an AM board. I got a new ASF top cover and everything fits together fine, however I have an issue with the steering.
Initially, the servo motor wants to spin only one way, unless the pot is thrown all the way to one side. When the board was installed in the car, the steering would lock all the way to the left as soon as the car was turned on (after binding to my radio). I removed the board again and connected it only to the battery terminals and found I could stop the servo motor by turning the pot all the way to one side.
I then followed the steps to centre the chassis steering found in this thread (http://mini-zracer.com/forums/showthread.php?t=39628), but with the pot centred by eye.
After doing this, the servo motor will stop spinning with the pot centred, but then the servo motor only spins when the pot is thrown to one side of centre and not the other.
My radio is an EX-1UR with a FS-TM002 FlySky module. All settings are default, and throttle works. The same thing happens with the FS-TM002 connected to an Airtronics M8.
Does anyone have some hints as to what is going on?
If I can't get this sorted I will go back to AM, but the plan was to upgrade this car to FlySky 2.4GHz, and put the AM board into another Franken-roller. If I want to run both cars as AM, I will need to get another AM top cover.
