I’d say the steering expo or curve. Go into that and bring down the low to mid ranges, and maybe just a small amount up high and try it. You can do it on the fly too, if you’re cranking the steering all the way immediately it could also be tuff to deal with, try a little bit of steering while...
On the speed you would decrease if it’s too fast, on the expo, or a steering curve you can also decrease. Did it come with a manual? Radiolink has a good manual filled with explanations
Recalibrate the radio. scroll through the menu and make sure it doesn’t have like a throttle trim turned up, with the radiolink though I can’t recall if it has something like that.
