I prefer it over my Tekin honestly. Hard to believe it's so good for the cost.)
The SCT-Pro is an awesome sensored ESC for the cost, it handles power very well, and runs at modest temps. It has a capable internal BEC that's never glitched on me, despite running a savox 1258 servo, leds, extra motor fan, and a transponder all at the same time. I use it in my Tekno SCT410 with their 3656SD 4000kv 4pole motor and it tears the local club tracks, easily keeping up with Tekin systems that were twice the cost. The sensored mode is very smooth and linear, it doesn't seem to jaunt at any point in the throttle range like some do and it's a pleasure to drive.
The field programmer you can get with it is really nice as well, it doubles as a per-cell lipo monitor and it allows you to modify ESC settings by simply plugging it into the fan port.
Since Hobbywing also makes surprisingly great mod motors, it's worth trying to get the combo version of this ESC if you can find the HW motor you like in the right KV.)
On the flip side, the bummer is the very weak internal BEC. It claims 6v @ 3amps and that is all your going to see from it ever.
If you run a high voltage servo like I do with my power hungry Futaba 9352HV, then you will definitely be needing an external BEC!
After about half pack and lower, the power loss to the servo is unbearable with mushiness to the point that I was almost out of the race with my truck turning like a tractor trailer on a right hand turn if you know what I mean!
For the motor, this ESC can't be beat and for the price point especially. But the onboard BEC leaves a lot to be desired.
If you do the math, this ESC with an external BEC like the CC adjustable 10amp will run you roughly $35 more than as is for the BEC and required castle link. So your looking at minimum of $125.00
If you plan on running an HV digital servo and can muster the extra cost, do your self a favor and just consider the new XR8 ESC for $160. Just $35 more for twice the features and no need for external BEC...)
I bought one (in other vendor) but unluckily burnt un about 10-12 LiPo. Nevertheless, probably I will purchase another one in the future.)
