A little clarity..
I said, "85%" in my post, thinking that those of us viewing this thread would have the understanding that it was out of 100% - on ANY radio. I have yet to encounter any racer using a percentage above 100, but that's not to say its not being used - just extremely uncommon in these neck of the woods. I would have to say that there's definitely a set-up issue with the chassis that's not being addressed, with that kind of d/r setting. I think we all would definitely benefit from each other's input if we can stick to the script. No right or wrong, here. Just what you do and why you do it? Maybe, throw in: how you achieve it?
Also, the exponential and steering speed setting would be set at the default / neutral position, which could be 100 or zero. Just depends on you radio. I'm simply saying, that, I don't change it.
