I am probably gonna get a stock summit and eventually go brushless. I just talked to a friend who said that the tranny is the weak point, that people keep blowing out the transmission... Anybody had trouble with the tranny? If so in what situations? I would think that sloppy shifting might be the culprit, but would like to hear what you guys have found.

thanks

So nobody has had any issues? I have heard that the problem is a loose linkage that can lead to blowing the low gear. Nobody has had a problem. I find this difficult to believe; please share.

I bought a Summit in June and before even turning it on went brushless with a MMM 2200kv combo running 4-6S lipo.

It's been sitting for over a month now with the stock stuff in it again because I am trying to sell it.
But the only thing I ever broke was a ring gear in the rear diff. One of the driveline pins is falling out but tape and a rubber band holds it in there well. The trucks are tough but you MUST remember to never shift anything while giving it power. Diffs only engage/disengage when still.

Mine currently looks like a Revo (wheels/body/wing) but has a brand new motor, extra parts, and a TQ4 2.4Ghz radio. I am looking to sell it all for CHEAP. PM me if interested.

I just got a summit with a Mamba monster set up ,
2x 5000 mah 3s lipos and drove 40 min and no problems

It looks like the problem only occurs when shifting is done during acceleration.

How does it perform brushless in second gear? I guess if the tranny did go, you could just clean out the broken gears and leave her in 2nd.

I got a video at vimeo , my son is running the summit not full throttle but i run it around the house and it goes fast for a summit!!!.

With the Revo conversion and 6S lipo I could clear the crossover jump at my local track in low gear. I never once shifted while accellerating but did accidentally leave the diffs locked a few times when running. Only the rear blew eventually. The trucks are tough. You won't be disappointed.

I have never had a problem with my SUMMIT.
