IIRC the Novak Super Duty is brushed only, VXL is a brushless motor.

Hey, I tried out teh Villain EX on a 6s A123 pack! Wow, it goes like stink.... I get about 7 to 8 minutes runtime, and guessing on speed I would say ~27mph (maybe ~23mph before with 5s pack?)

It has alot more get up and go for sure. The thing I don't get is that even when running the motors at roughly 17 volts under load, the motors were no phased one bit over the 5s packs... maybe they are just getting that much more water because the extra speed... water pickup... well you know.

Just thought I would share that.

Interesting. That sounds like a good speed to be at...perhaps. But 7-8 minutes of runtime? I'd like to shoot for something a little longer.

Yah, i know, the runtime leaves some to be desired (well alot), but i have 3 packs, and after the second pack, i usually just quit so it's fine for me. BTW, the 8 minutes is full throttle the entire run, never letting off. So ya, boats take alot of power to move at a given speed.

If I went and got a 5s lipo pack, it would be same idle voltage, but much higher under load volts... more power and speed, probably alot more... and twice the runtime as well.

aha. So...if I happen to stay with the two 380 sized motors that are currently in the hull, would I happen to burn them out if I was running a 4S in the Super Duty?

Or should I switch them out to a 540 sized motor?
