These are REAL servos!!! Excellent upgrade for anyone needing to replace a EFLR7140 Eflite 13g. When you open the box you'll know why. The Eflite ones are a joke compared to these. These will be on all of my smaller planes from now on. Plus these are cheaper than the Eflite ones... enough said.

I have always used Spektrum and savox and never had an issue. This is my first Hitec servo which I purchased based on their good reputation and i am not impressed. It started to smoke within 60 seconds of turning it on... And wasn't under any load. I was trying to get my 5yr old son Yeti Jnr completed for his birthday which is impossible now considering US to Australia shipping wait.

Excelent servo! Highly recommended. The servo is strong and perfect for ailerons, rudder or elevator. Plane sizes 1.2 - 1.3 and 1.5 wingspan.

What reviewers say

Reviewers are split on the Hitec HS-85MG micro metal gear servo. Two reviewers praise its build quality and strength, one describing it as a better alternative to Eflite 13g servos at a lower price, and suggesting suitability for ailerons, rudder and elevator on planes of roughly 1.2 to 1.5 m wingspan. One verified owner reported the servo began smoking within 60 seconds of power-up without any load, and described it as a first Hitec purchase that did not meet expectations. The sample is small (three reviews), so the single failure report cannot be assessed for how common it is.

  • + Strong for its size
  • + Solid metal gear build
  • + Suitable for ailerons, rudder and elevator
  • + Lower price than Eflite 13g equivalents
  • − One report of smoking on power-up without load
  • − Only three reviews, one negative
