New Peak Sensored Motor System




Spotted at a recent practice session is this new electronic speedcontroller from Peak which has the capability of running both brushless and brushed motors. With brushless systems becoming more and more wide spread Peak Racing is about to pick up the trend of bringing power to the brushless motor, and it would seem odd if a series of brushless motors wouldn’t be released as well.

SMS is not the ordinary type of sms, short message service, that we all know very well and criples your fingers, this one is targeted for your trigger finger, it’s short for Sensored Motor System and targeted for the RC scene.


As far as we’re informed the SMS can of course be programmed and will include features such as:

Rotational speed limit (Brushless motors only)
Timing: 0°, 7,5°, 15° or 30° (Brushless motors only)
Current limiting
Current rise function at full-throttle
Brake minimum
Brake maximum
Start-up current limiting
Automatic brake
Frequency mode
Power curve (soft, linear, hard)
Automatic throttle
Full brake
Maximum reverse speed
Switched functions
ABS brake function
