i also race at tftr i just recently moved up to modified from 8.5 brushless. You do not have to be a member to race you can just pay your entry and away you go. i will be there for a couple of hours in the morning as i have to go to a family lunch. But Tommy and myself will be more than happy to share set up tips. i think the servo is around 115 to 130. ask Tom see how much he can get one for you for. I think he uses KO Gear so that also would be an option best to ask him when you pick up the car.
