When you receive it you can let us us all know what the voltages are ...

My blue RCsmart ones were also supposed to be 12V max, but ive heard of teams using them on 14.4V. Still the numbers on this one dont make sense.

But it might be worth a gamble, who knows.

Thank you, both.

Is that plate for cooling in the third picture?

Thats the PCB carrying the second tier of mosfets, that makes a Scorpion XL into an XXL. This is a homegrown version of the XXL, and is as you can see, squeezed in a box with a pull/push microfan combo.

Speed Controller

Thanks. Do you find the fan necessary?

[leorcc]

Speed Controller

Short answer: yes
Long answer: It might not be if the motors are not too power hungry but ours definatly are.

Would you recommend some form of filter on the fan to stop debris?

[leorcc]

Speed Controller

Yes, we put a fine wire mesh in front of our fans.
