Nice! That system must run really cool.

Cool video...that thing is quick!

Very nice. What made you go with the 70mm can vs. the 60mm?

Because too much power is just right! I love torque, and I also figured that a bigger can will run cooler than a smaller one. I don't like to push my stuff if I don't have to. Sumertime down here in Texas can be brutal, and as a result I design my rigs to run cool so I can play anytime I want to. That setup there with me running around is maybe hitting 120 - 130. That's only running on grass, I expect it to be cooler on a track where it's not in a high-amperage situation all the time.

As it is (15/46) it runs great, is controllable, runs cool and has wicked acceleration. I think the runtime is at least 15 mins, probably longer. I haven't timed it yet. Definitely going to have to get out to a track now.

That video was awsome in HD. You've got a reall nice running buggy there. I have the 80mm 1600kv medusa on order and I can't wait to try it in my truggy or muggy.

Nope, 1P.

OMG

I am running similar setup HB L2PE buggy, Medusa 36-60-1600 14/46 and have 8 min runtime...

What's wrong with my setup? Should I use bigger pinion?

[Metallover]

I think jones may have been a little light on the throttle.

Really hard to tell. Driveline drag? Different motor size? I'm not sure I can pin this one down for ya.

That, my good man, is unlikely. :)

A bigger pinion will probably shorten your runtime - if anything, try a smaller one.

I feel it is undergeared.

Gearing is not that obvious with four pole motor

I will check it with ET.
