Maybe it's a good idea to put a report of every little tweak/ modification you did yourself in a certain situation.
Did it work? or Didn't it?
If it worked we all have something to try and TX would get feedback of things to try in the future...
I live in Belgium and in our Belgian/ Dutch championship we drive on astro, dirt, clay and an indoor multisurface track. I've experienced some different behaviour of the car according to the surface but after some tweaking with the setup and the behaviour of my throtle finger I achieved a good driving car in all the situations with a nearly standard '08 pred (short pushrod, changing droop in the back and the front,standup servo, etc. were the mods I used) .
BTW on the pred.co.uk there are a lot of practical tips and tricks but I guess you guys knew that allready
So in my opinion the pred doesn't need the wheel to be reinvented, but a few little updates are allways a welcome guest.
