Any idea on the tires? I think 26mm will be the widest I can use on 1/10 sedan.
No there is no way to compare the two systems accurately. What you will see from the manufacturers is an approximation. If any one says any more than that, they are wrong. Brushless and Brushed have fundamental physical limitations that will never make them comparable; sorry. You can get close, but the power band is so much different, and efficiency so different along with other tings, it can never be a true comparison.
ROAR does have rules on tires, depending on what class (foam or rubber), etc. Rubber class is more strict, but foam sedan (usually only used on carpet) has a max width of 26mm, but it is common to see 24mm for efficiency, etc.
