Going brushless after all!
I’ve decided to go brushless instead of brushed with a view to adding brushless at a later date. I had a turnigy motor and Hobbyking ESC sat in the spares box and have ordered another pair. Will run this on 2S lipo to start with and go 3s i …

Brushless ESC + Motor
The brushless ESC is now in, its un branded but is rated for 50 amps and up to 22V so should easily be able to handle the motor. I connected it up to the motor and it works ok just a little cogging at low speed because the motor is sensorel …
