sigh... if that was the case dont you think there would be a 9000kv 8th scale motor and a sweet computer program...
I will admit that i think the 1900 is a bit low for my tracks, the 2050 seems great and i can clear the triple and still slow the car down for the turns. A 2200 in a truggy style car works well also for my track, but i think on something as light as the rc8 it would be way too much top end and nother enough umf to get over the doubles and triples... to each their own
