update with the savox
I decided to replace my wheel controller and buy a stick model, sooooo I bought a core-rc code digital model of ebay (second hand), great thinks I finally saved a bit of money there.........
nope...turns out the core-rc model and savox don't like each other.
it works but the steering is jittery
found this video on YouTube and the uploader informed me it was the core isn't compatible with the higher spec servos
i have the same as this video.
