I have converted my Axial SMT10 to 4 wheel steering.
The front servo is a Blue Bird BLS 2905 with hot racing servo saver. This front servo is powered by a 10A castle BEC set to 7.4V and it is controlled by steering channel as normal.
For the rear i have a JX CLS6327HV which is using the Max10 ESC BEC which is set to 7.4V I have not yet fitted this with a servo saver. To control this, i have plugged it into the third channel on the receiver and used 3/4 of the available positions on the third channel (left, centre and right)
To set this up i used this great video from Beyond the Scale

New Motor has gone in, 4092 1650KV. still using same 16/48 gearing as before. Max motor temp during these runs was 90c without heatsink. This motor will get a fan, but not a heatsink as it has fins on the motor.
