Would this fit a Tamiya Monster Beetle?

Does it work for 10.5 t motor brushless to ?
Asked by Marian on 30th May 2020

No these are brushed only

Answered by: Ben @ Wheelspin Models

I’m aware that the SC3SWP2 Speed Controller states that it can handle brushed motors down to 12T? does that also include using high speed gearing ratios on a 12T motor with the ESC?
Asked by Matthew on 23rd September 2020

That's an estimation.

If you are running extreme gearing, then your current draw will be higher - so I'd take the 12T limit with a pinch of salt in such cases

Answered by: Ben @ Wheelspin Models

Before I purchase this item I'm wondering if this will fix my issue. No power going to rear wheels, motor is working as I've connected this direct to battery and front wheels are also turning. Any help would be much appreciated. Thanks John
Asked by John Furniss on 21st January 2021

If the motor is confimed working, then yes the ESC would be the first thing to check
