I live at a elevation of 3600 feet and if i tuned my nitro car at home and then went to revrace to race i would have to retune the whole engine.
when you get to revrace you have to stand in line on the drivers stand and wait your turn to drive and tune your car.
Now that i have switched to elec i just show up and i know how my car is going to run and i can concentrate on my driving and actually tuning the car and not my power plant.With the use of a Tekno conversion my car can even be driven like a nitro but with a lot more over all power.It works for me.
