KingMax BLS6013 - product review

KingMax BLS6013

We’ve been asked to test the KingMax BLS6013 servo. The servo was nicely packed in a plastic container.Out of the box you feel immediately the quality of the servo and it’s metal housing with the cooling rib’s on the outside, highlighted with red anodized accents (also available in gold and silver).

The servo has 25 tooth an comes with a few servo horns, even an aluminum one.

We’ve put the KingMax servo in our Element Sendero IFS to test out this servo. The servo fits in nice and snug as it should be. We plugged it in to the receiver (don’t forget to set the end point of the servo, because it will break down as any other servo or you will ending up with a broken car because of power of the servo). We tested the servo on the Scale Adventures crawler trail, the servo is turning real smooth and is not making any unnecessary noise. It steers very smooth, even a small correction is possible with this servo. At the rock wall we did a stress test and it held up very well. Even when the wheels got stuck between some rocks,  it hold up and didn’t break down . The servo is really strong with its 64 kg at 8,4 volt even on 6,0v it can handle 51,0 kg. Crossing the water was also no problem for his watertight servo. We’re very pleased with the looks and performance of this servo and couldn’t find any downsides while testing we will go on testing this servo for the long term. So you’re really getting a powerhouse in your RC car when you choose this servo.

Great work KingMax!
