Anyone using BK servos in their large scale models?
if so what are your toughts?

Never heard of them.

They are popular in the heli world.

Oh, I thought Burger King was selling servos now.

A helicopter flyer at our field is a BK sponsored pilot I have seen the servos in action they performed very well. I do not see the pilot often so I have no knowledge about durability longevity. He said they center very well and held positions very good. But remember he was sponsored by them, he was flying 700 class 3D helicopter so he did trust them

BK = Bert Kammerer = profesional heli pilot and distributor as well.

they are just rebranded Servoking servos (made in Taiwan) https://www.servoking.tw/

he was also the distributor of a custom Pizzabox 14

Would that be the BK vegan servo ?

I have seen a heli with them that has done over 1000 flights of smack 3d with them this heli has been decked hard a few times breaking links and bending servo arms and all are still going well in that heli
Just wondering if anyone is using the ones for fixed wing?
I have a set for a heli that im fitting into my 700
might give a couple of the fixed wing ones a Try in my new 50cc Extra as a test rather than testing in a 3.1m extra

Actually not quite correct they are built in the Servoking factory but have different motors pots and boards and different specs.

prove it. thanks.

I gave them a shot a few years back. They are great servos but definitely designed for helis. The movement torque is quite good but stalled torque heats up the motors and they go into limp mode quickly on a fixed wing.

Say you're doing something like a knife edge. The rudder will slowly move to neutral and then go limp until the motor cools back down and tries again. I was also able to replicate this on the elevator with long loops and the ailerons with just a few continuous rolls.

In no way am I trying to knock the servos! They really are good quality. They just aren't what a fixed wing needs.

I fly them in one of my helis. They are incredibly fast. It’s something like .03 sec/60 degrees. They do get hot. In helis they are typically in the rotor wash and have good airflow all around them. With all the decks in a heli being controlled by a flight controller the added speed makes sense. I doubt there is much benefit in an airplane.

What servos do you use now in that same plane ?

were they the heli ones or the ones designed for fixedwing?
