Jelly Maker!Review by NEFARIOUS
All my friends are jelly i got such a good looking, fast, torquey, well centering servo when they spent up to $50 and didn't get half of that value! Making them.jelly!
All that and it only uses rhe 6vokts from my receiver, no extra BEC, no wire adapter to my LiPo, nothing extra, just plug and BASH!
It matches the beautiful blue of the Hobbystar Gyro , ESC, and Motors perfectly! Thank you RC Juice! (Posted on 7/30/2023)
Extremely fast for a 6v servoReview by Dylan
Put one of these in my arrma big rock and so far it seems great. Gonna get to give it a proper bash tomorrow but I’m simply amazed by how fast it is already. From what I can tell it definitely has enough torque for the job too (Posted on 2/22/2021)

Will this fit the losi 22s drag car?
It appears that the Losi drag car accepts standard size servos, so this will fit.

Is this waterproof? Is it appropriate for 1/10 4*4 sct? If not do you have one that's better for that application?
This servo is not waterproof, however, is a good fit for a 4wd SCT application.

Would this servo be good for onroad club racing with a tamiya tt02 chassis??
It's a great servo for 1/10 vehicles that demand quick response and torque. Perfect for on-road applications.
