Here is a brief explanation how I operate my dyno with a brushless setup.

1. Install brushless motor into dyno as you would a brushed one.
2. Connect a brushless ESC to the motor.
3. Connect ESC to Receiver as you would if it were in a car.
4. Connect 4.8-6v supply to one port of receiver(I use 4 cell 150mah battery pack)
5. Connect Power Output from dyno to main battery input of the ESC
6. Turn on transmitter.
7. Apply full throttle on transmitter at the same time as starting dyno test routine.
8. Upload plot to the Internet and post results here .

This method tests ESC as well as the motor. By using the same motor different ESC can be compared.

Here as some comparison that I think many racers would love to see:

Various ROAR spec motors

eg, 10.5, 13.5 & 17.5

Brushless - Brushed

10.5 - 19t
13.5 - 19t & 27t
17.5 - 27t
21.5 - Silvercan

Various ESC.

Novak GTB/XBR, Speedpassion, GM, Tekin etc

Efficiency of low wind motors for use in 5 cell modified racing

eg. 2.5 - 4.5 turns.

If anyone is generous enough to post dyno plots could they please add text of various data incase we lose the picture.

Regards,

Jevon
