To beat the nitros, drive better.

The next statement usually is "If not for power it's not worth it", that's usually before They realize I'm still running after their 3rd or 4th pit stop. I still say that Novak's are the best racing setups for buggies and MT's (despite running hot and being a bit behind the times, hopefully the "next gen" setups will improve on that), simply because they do the best at mimicking the nitro's speed and overall power. I might get blasted for that last comment, but it's my belief

BTW, I have raced and lapped the field with a Novak hv 4400(pre-sintered rotor). I have yet to really run a true high power setup in an official race, I hope to soon, but i will still be using nitro's speed to help setup my trucks

I agree that the Novak HV system is smooth and I had some success with it in my buggy but unfortunately the system is not engineered properly and will eventually fail. I'm not sure how Novak keeps up with all the warranties for these esc's. I'm also puzzled why the HV's seem to work OK in MT's and fail so often in a buggy.

I think it's direct drive verses a gearbox/slipper setups, only thing i can think of. May also be the body is higher and allows more air to cool, Buggies don't have much room for air vents

tranny vs. direct drive?

The revo's slipper clutch can help reduce the amount of initial current.
Unless you run RCM's slipper diff, then its possible that the buggies direct drive may pull more current than a MT.
The MT's may also soak up bumps better than a buggy which may keep the fans from failing as easily.

The HV needs proper cooling or it will "let the smoke out"

thats it! the center diff, it unloads pulls more current. thats why hv's fail with buggys. your good...

Sorry for side tracking the thread...

I think you're right. If the fan looses teeth or fails at all the HV will go up in smoke. If any esc requires a fan from "letting the smoke out" then a built-in thermal shutdown should be required as well. Whats funny is that the HV motor has this feature but not the ESC...
I'm interested to see Novaks 8th scale ESC though. I haven't heard anything about it lately though
