Not sure why the complaints on Hitec servos. Have also been using them for decades with confidence.

Not to say have not had problems, their 2 series were problematic from the get go.

This is true with other makes, Futaba included. Just burned up several rated for 6V when powered with a 2S LiFE. This does not happen with any others I have tested, including Hitec analogs.

Agreed that it can happen with any brand, but curious as to which Futaba 6V rated that you burned up with a LiFe battery. That's all I use are Futaba servos and LiFe batteries and have yet to have an issue. I know you have to watch though, trying to remember the particular model number, but Servodatabase says it's 6V, Futaba themselves say 4.8V.

Re: Heads up on servos

I've owned several known brands over 50 yrs, with very very few issues.

My complaint is with the Hi-Tec failure mode that I experienced..
The one I had fail, literally burned up and charred the servo mounts. Luckily the ensuing battery failure was covered by my use of a Power Safe receiver (the 2nd battery survived!).

IMO, it is not acceptable for a consumer electronic product to fail so spectacularly. I.E. it should simply stop working on failure.

BTW, I still have many Hi-Tec servos in use.

Re: Heads up on servos

Two Hi Tec that puked on me were extremely charred. The small one did eventually quit but the quarter scale.size was still cranking it out. The heat when my hand got about an inch from it was the tip-off

Re: Heads up on servos

Two other reasons for servo heating are incorrect frame rate from the Rx, (yes, some can alter that output frequency).

The other would be constant loading that forces the servo to keep trying to hold position. Same with tying it to a gyro or stab system that asks for position changes constantly. Saw this with some low quality heli tail servos.
