1/10 esc and motor

[Soccerrevo]

What is the KV limit on the 10.5 spec limits? I have noticed that many manufactuers have different KVs but are all 10.5?

I was looking at this for a future Blitz perhaps...

I can't find anything on Kv rating but more about how a motor is built including the number of winds,10.5 winds.




ROAR Spec 10.5 motor: Only three slot “Y” wound stators are permitted. No delta
wound or slot less stators are allowed. Only circular (round) pure copper magnet wire
permitted. The three slotted stator must be wound with 10.5 turns of 2 strands of a
maximum diameter of 20AWG or 0.813mm and two strands of a maximum diameter
of 22AWG or 0.643mm per slot. The resistance for each slot of the stator shall be
tested and a minimum resistance figure will be determined upon submittal.



General:
8.8.1.1 Sensor based or sensorless motors are allowed in all electric classes.
8.8.1.2 The owner shall be able to easily replace the rotor, bearings and front end bell using
commonly available tools. These parts shall be available for separate purchase. Ball
bearings are allowed.

We don't specifically follow Roar rules but more as a guide. Castle motors technically don't meet Roar specs for 10.5 or above because: All motors must have the original manufacturer’s logo or name molded into the end
bell. ROAR Stock, Super Stock and Spec motors must have a distinguishing feature
or mark not easily removed/altered on the stator stack or collection ring designating
the wind number.

Castle motors are Roar approved for mod though. I believe we let 4600kv Castle motors run in the 10.5 class.
