Very good quality runs cool for my application off road. Arrma Granite. (Posted on 6/23/2017)
Solid and silky smoothReview by Mr.D
I like this ESC, its my second Hobby Star, and so far it seems just as solid as my previous one. I'm using it in sensored mode with a 8.5T HobbyStar modified motor in a Sakura D4 drift chassis and it is silky smooth, a definite upgrade from my unsensored setup that this is replacing. It is a little bigger than I thought it would be, and probably overkill in my drifter, but if I ever convert back to 50/50 and through grip tires on it, its nice to know the headroom is there to make a screamer.

How would I bind and calibrate this esc with an older Traxass tx and rx? I can get them to work together but looses power responsiveness exponentially
We see more issues with Traxxas radios than any others, they can be very problematic to calibrate to any aftermarket ESC. Unfortunately if you have an older radio you may experience even more problems and it may never work porperly.

What motors can I run on this with 4S?
Any 1/10 motor rated for 4s use can be used with this ESC.

Would this make a good choice for a tenacity SCT with the metal chassis?
These are great ESC's for 1/10 short course trucks!

Are these waterproof?
The ESC is but the fan and switch are not so they do not get a full waterproof rating.
