A short update:

The MM esc has been working great, so decided to push it a bit more and thru a new 15 cell GP3700 batt on tonite. Peak voltage was ~21V, so I think its still at a safe zone with the 25V caps, but pretty close to the edge.

I've wanted to get a radared run in, so figured this would be the time to do it. :) The good news is nothing exploded, in fact nothing even got hot, granted it was only 65F outside (100 esc, 140 motor.)

I did 5 passes, but they weren't as consistant as I really wanted. I had a long stretch of open flat road, ~100 yards run-up to me, and a clear parking lot in back to slow down. The speeds were as follows: 46, 49, 43, 41 and 41. I am throwing out the 49, just seemed a bit too fast. I do have a rustler that has doen 48 reliably, and I'm not sure this was faster, but this was pretty close. Hard to say..

It was quite a bit faster than the well-used 14 cell GP3300 batt I normally use, which I was *guessing* was pushing the truck high 30s-40.

OTOH, something did blow up after the first few runs, the bearing holding the top gear. It started wobbling and caused the spur to strip a bit. My radar techinique is good, I start measuring about 60 yds out and hold it until ~15-20yds, truck moving straight at me (sometimes have to jump :) .)

So I'm not sure where I'd put the speed, but def mid 40s doesn't seem too off. I'd like to do some more runs, but pulled it in to check temps and the god awful noise under breaking and discovered the messed-up input gear and packed it up.

I'd love to drag a nitro and really see where its at. I've only driven a nitro once (a 2.5 tmaxx) and it was no where close. Has anyone seen any radar/GPS speeds for some nitro Revo's? I know TRX says 45+ for the 3.3.

Edit: Did finally get a single st. servo a while back and moved the esc down into the other slot. cleaner and more protected that way. I've had some pretty good flips and crashes bashing off-road, so the tucked away esc truns down the cringe factor a few notches on impact. Have to say this Revo is TOUGH. :)
