Boundary testing for us = Formula RC update for you. http://rfactor.net/web/rf2/cars/ (Bottom of page) Ideally you can use an adapted R/C controller or game pad. If you have to use a steering wheel, we recommend setting the steering range to something like 120 deg (which on most wheels is done automatically), and enabling centering spring set on maximum. For those who have never driven an R/C sim, it will be very difficult to acclimatize, especially to driving from track side cameras. If you’re enthusiastic about this, and give it time, it will come to you. We have 1 circuit for it: Lime Rock Park — R/C. Trackside camera Group 1 allows manual zoom controls; with default zoom it will be difficult to see the car at the far ends. The circuit is bigger than a typical real life circuit. Group 2 has autozooming, but does not allow for manual overrides. The car was partially done as an experiment and private project, and did help to track down some issues. Boundary testing like this, you often find issues much quicker, by experimenting with the abnormal. The car is rather powerful, it has one of the best engines available in 5th scale racing, to help tame it, setting taller gear ratios may be of benefit.
