The ProTek 500BL Mini is the next step in mini servo performance. Developed for 1/12 and 1/10 pan car, as well as 1/10 Pro Class drag racing pan car style chassis that use a mini size servo, this brushless option produces 186oz of torque and .06 transit speed at 7.4 volts - with superior efficiency and lifespan. Backed by a Lifetime Gear Warranty through Amain Hobbies for added confidence and durability.

A black anodized aluminum case with a blue anodized bottom cover provides a stealthy and clean look. The aluminum case allows for extreme durability and a precision fit for the servo gears to provide the precise control necessary for demanding enthusiasts. Metal gears and brushless circuitry round out the package to create a robust option that will go the distance in high demand applications.

Jerry VolpiniVerified owneron ProTek RC 500BL "Black Label" 1/12 High Torque Brushless Mini Servo

Excellent servo! Very fast and plenty of torque. Its hard to find a mini servo with specs like this. It has excellent centering, is smooth and very quiet (during use or ar neutral). The aluminum case dissipates heat well and this thing runs without a hitch. It's not cheap but a case of "you get what you pay for". Great looks too! Running in a mini crawler and this thing kills it!

Love this servo! Powerful and fast, all that awesomeness packed in a tiny box! Fits perfectly in my CRC Ck25

Andy SzmidtVerified owneron ProTek RC 500BL "Black Label" 1/12 High Torque Brushless Mini Servo

Excellent little servo. Works great in my Hackfab mini oval cars.

Liam GenselVerified owneron ProTek RC 500BL "Black Label" 1/12 High Torque Brushless Mini Servo

HEAVY but strong. I keep it as a backup servo for my pan cars

Neil DrakeVerified owneron ProTek RC 500BL "Black Label" 1/12 High Torque Brushless Mini Servo

This is a good servo but beware, replacement gear sets are NOT available. If you strip gears in this as I have done with a 1-week-old servo, it is NOT repairable. $90 gone...poof Use a servo-saver. Unfortunately, I did not. Amain was very nice on tech service call, but there is also no warrantee for stripped gears.

What reviewers say

Reviewers generally rate this 1/12 brushless mini servo highly, praising its speed, torque, smooth and quiet operation, centering, and heat dissipation from the aluminum case. Several use it in mini crawlers, oval cars, and pan cars, and report reliable performance. Reviewers describe it as somewhat heavy and expensive. The main recurring concern is that replacement gear sets are not available, and one owner reported a stripped gear on a new unit that could not be repaired and was not covered under warranty, advising use of a servo saver. Overall sentiment is positive, based on seven reviews, most of them verified owners.

  • + Fast and powerful
  • + Smooth and quiet operation
  • + Good centering
  • + Aluminum case dissipates heat well
  • − Replacement gears not available
  • − Stripped gear not repairable or covered by warranty
  • − Heavy
  • − Expensive
