[JB3231]

I tried the B4 for an onroad basher with a Mamba Max 5700Kv and Lipo 3S. The motor placement does not work well. There is too much weight in the rear and it just wheelies at all speeds. I was getting 60+ mph out of mine but I could never just punch the throttle. I had to try and ease it up to top speed. Also the tower's get completely destroyed if you ever flip it over on concrete.

My next project, very similar to yours, will be something 4wd and have much more weight bias towards the front. I would recommend something like a 1/10th 4wd buggy with street tires. Maybe a Losi XXX.

Also the B4 with that much power will burn the tires up after 2 packs. Mine were completely bald after 2 runs in a parking lot.

Hope this helps since I just tried the same thing.
