Your track appears to be slightly bigger then the two I race at, straight is about 100ft. After some reading I did find that one of our local pros also typically uses a 1700kv from tekin. Which also makes me feel a little better. I can't help that I am a typical power hungry American.
what I ended up picking up is a Orion r8 pro and a Mr8 1750. I seriously hope that works out.
are you topping out on that back straight?
