That's my point.

A 4S powered monster can do 50mph, try that with your hvmaxx.
I thought I just said that the novak motors (at least the ones with the sintered rotors) don't have overheating issues and the feigaos do. Also I never denied the fact that the feigao xl motors are more powerful. My point was efficiency. The feigao motors have a wide gearing range but, there isn't a gear ratio that doesn't create heat. The novak motors heat up only when they are overgeared. All you have to do to fix the torque problem w/ the novak motors is GEAR LOWER. Since a hv4.5 has more than twice the kv as an 8xl, there's a lot of rpm ot spare. Before you fire back at me at how lower rpms are more efficient. I'm still willing to bet that a novak motor spinning at 60,000 rpm is more efficient than a feigao motor spinning at 35,000 rpm. Plus the design is completely different so their "sweet spots" are at different rpms. Also, what are you using to get a 50 mph 4s powered monster, whose motor DOES NOT overheat and is not a neu or a lehner. I hope you are not referring to the 8xl, because I've never heard of a motor that pulls 11:1 FDR's in a monster truck, because that's what it would take using 6.5" tall tires. I apologize if I sounded harsh.
