Yesterday I drove my new car with a HDKJ DS3020
HDKJ DS3020 20kg metal gear, large angle, large torque, digital, waterproof steering gear, All meta - ????????

Bought a while ago 2 of them for just 33 euro a piece. 0.06sec, 20kg and brushless seemed a good deal. There is some latency when I connect it on my servo tester compared with a Align DS615 (Savox 1257 like servo) but hardly noticeable. But was doing ome practise laps on my crowded track with my 1/8 onroad and I could place the car fast and everywhere I wanted it.

So far I am pleased!
