GD, thanks for the post. I believe that I read someplace on this forum that I'd lose something over a pound of weight going with the Maxx type tires. I guess I really have to keep in mind that this truck weighs a ton in its current form and getting all of that weight (and the rolling mass of the wheels/tires) moving is a chore for the motor/esc.

I haven't had any problems with the MGT conversion, but on the other hand it is geared very conservatively. It tops out at around 25mph, but gets there in the blink of an eye. At this point, I don't mind sacrificing speed to get the big truck moving well and without cogging.

It is warming up down here. Actually, it's starting to get hot and yesterday I noticed that the esc is running noticeably hotter than the motor, so I'm figuring that I'm still overgeared. I guess these monster trucks aren't built to go fast. Maybe I should have set my sights on a Revo, rather than this 13lb monstrosity.

OK...you might be able to tell that I'm starting to get burnt on this issue. The conversion didn't turn out the way I wanted. Unfortunately, I have to figure out what I'm going to do now. No one down here is interested in a Muggy, because everyone is still hot for the 8ight/T.

Another thought that I had was maybe going with a bigger motor. Maybe a Lehner 1950 series. I think that there is a 1700kv model. Perhaps that would be the ticket in being able to get the truck moving without all of the cogging.
