this one's is the cream of the crop...this is why I bought one thanks Richard and special thanks to Juan great chassis!

I don't know about all that, but thanks for the compliment. Mine is one of the originals, cream of the crop is to be determined yet "thumbsup"

How's the rooster holding up to the 3s? I thought it can only handle 2s.

Specs that I know:
-Underground Crawler Fastback Chassis (of course)
-Rovers on all corners
-HR aluminum wheels
-Underdrive Rear Bevel Gear
-Metal front and rear drive shafts
-HR Alum tranny case with all metal gears
-Mamba Max ESC
-Integy 35T motor
-VP Dig
-Losi Shocks
-Axial BTA Steering
-Hitec HSR-5990TG steering sevo
-Yeah Racing 3s 1000 mah
-Castle BEC
-Custom rear axle razrs - thx Tom

it works great on 3s

Hmmm. Interesting. That's quite a big jump in voltage. Does it get hot at all? What kind of run times do you get?

you have to run an external lipo cut off but other then that they will run just fine on 3s.......ive seen a bunch of people doing it for a good amount of time.....no issues

And external bec, but the should be standard fare on a crawler unless using a Holmes esc. "thumbsup"

well yeah that is if you want any steering lol...or your rx not to brown out and failsafe........

looks like your hood spacer broke or something, cool shot though.

nope it didnt break....im using a pintle chain plate to give my 3s a little more clearance

How interesting.

btw the info came from novak.........and not the first time its come back to me as info people got from novak....but i agree with dickyt about the bec as well...usually think of those as a standard item as well
