hey noel,
I agree with what you are saying. Although my advice to most new guys is not to play around with setup too much unless the car is diabolical!
To be honest most of my rc experience is off-road electric with a little ep tc thrown in, so i cant comment for sure on this, but watching nitro on-road cars with foam tyres they seem to set them up with more uundersteer than rubber tc. I might be wrong. This tends to require more steering lock. Typically though, most tyres (full size and rc) have a traction limit and if you keep just cranking on more lock you dont corner any harder- you just scrub the front tyres more which leads to more wear and more work for the motor to overcome.
To test this out, find the fastest sweeper at your local track and try going through it at full lock while progressively limiting your steering epa. You will be surprised how little lock you need at high speed.
Aside: a lot of problems with 'corner exit oversteer' are actually caused by using too much lock through the middle of the corner. When you apply power you have too much lock so the car spins. This us true for full size as well as rc.

This is what I always tell guys who ask for advice. Never apply full throttle unless the front wheels are straight.(your point 5 Ray) However the trick is being able to feed the power on earlier in a corner which will increase your exit speed. I think this has alot to do with car set up. An untidy handling car looks fast on the track and a slow looking tidy car is actually faster. You even question yourself when your car is dialled, As in gee my car feels slow but alas the times dont lie. All of what I have said above is mentioned in Ray's post, I just wanted to reiterate his points which I think are all spot on. The steering lock point Ray mentions is good. You need to find a set up so as you need as minimal lock as possible to get around corners as this will enable you to carry more corner speed as the front wheels are not needing to turn as much to get around the corner hence then you are not washing off as much speed. I noticed this a while ago when looking at the top electric drivers up here in QLD there lock was not as much as what you see on the nitro tourers. Please correct me if I am wrong Ray.
Great reading Ray.
