Strong Servo! Installed in An Axial gilamon on 5.8 Swampers. Best bang for the buck. Not a 5 star rating because its not waterproof. Time will tell if this holds up like the other big brand servos.

Frank JonesVerified owneron No Superior Designs RC RS1.5X Extreme Torque Brushless Servo (HV) (High-Torque)

This was bought as a replacement steering servo for a Redcat Racing vertex 10 W that I also bought at A main hobbies. The servo seems really strong and it’s doing its job perfectly. I’ve bought so much stuff from A main hobbies that I can type a in my search bar and it auto fills the rest… always fast shipping, competitive pricing, and customer service second to none. They’re my go to hobby store for anything hobby related. I always search A main first, and if they don’t have it, then I look elsewhere.
