Bill ChristiansenVerified owneron Tekin RS Pro Black Edition BL 1S 1/12 Sensored/Sensorless Brushless ESC

Do not buy this ESC if you plan on using it for 1/12 Mod. Despite Tekin's claim of 1S, 3.5T capability, this ESC will overheat and shut down if anything less than 10.5T is used. I contacted Tekin directly and they stated that this ESC was "Fringe" for Mod usage due to the plastic case it uses. They also stated that their Factory Drivers still use the RSX with a voltage booster. I installed a fan as they instructed but this did not solve the problem. I will be returning this product and tying something else. This is very sad because I really like the Tekin firmware and Hotwire system. I have been a loyal Tekin user for many years and this is the first product from them that has been a complete disappointment. As mentioned, the RS Pro 1S works just fine, as long as you use it for 10T and above.

I already have tektt1161 and they work very well,running 6.5/10.5/13.5 turns. The brakes are very good with great adjustments.

I'm using it with 6.5t/13.5t 1s without fans . Very Smooth and powerful. Breaking is the best on the market

What reviewers say

Reviewers are divided. Two of four ratings are 5/5 and praise smooth, powerful throttle response, strong braking and adjustability, with one reporting reliable use on 6.5T, 10.5T and 13.5T motors, some without fans. The 1/5 review, from a verified owner, reports overheating and shutdown on motors below 10.5T in 1/12 Mod use, says the manufacturer described the plastic case as unsuitable for Mod, and says a fan did not resolve the issue. That reviewer plans to return the unit. The reviews do not clearly show whether the overheating problem applies to all units or only Mod setups. The reviews also do not clearly establish whether the 1/12 Mod issue applies to racing use.

  • + Smooth and powerful throttle
  • + Strong braking and adjustment options
  • + Reliable with 6.5T to 13.5T motors in reported use
  • − Overheats and shuts down below 10.5T in Mod use
  • − Plastic case reported as unsuitable for Mod
  • − Fan did not resolve reported overheating
