I've only been the owner of my E-Revo Brushless for around two weeks and have only taken it out 3 times (once with the stock NIMH batteries and twice with 4S Lipos). I'm quite new to the hobby but did own an E-Maxx Brushed for a few months before. I did do a swap with the 65T Spur to the 54T when I started with the Lipos but only after a few runs the pinion gear set screw came loose and the pinion stripped the 54T spur after coming lose on the motor shaft, at least that's what I think. I ended up putting some medium strength loctite on the set screw but now I noticed that the transmission is binding when I roll the truck without the gear mesh so I haven't taken it out since. It doesn't bind constantly just every foot or so when the truck is rolled. I can see the slipper clutch and the driveshafts jutter when it happens but the sound definately is coming from inside the tranny. It is a new truck and I cant see how I could of done anything to it because I only have driven it on concrete and have taken a few small jumps but nothing at all serious that could affect anything. The only thing I've done is replace the spur and that already messed up and I don't really want to go about taking apart the tranny if its something else. The truck still rolls so maybe it needs to be broken in???
I think the noise may even have been happening when I took it out of the box because it seemed noisy when I rolled it even with the motor resistance but I didn't think anything of it nor did I try to roll it without the gear mesh. I'm just wondering if it's safe to drive or should I avoid using it until the truck rolls freely so the tranny doesn't mess up further along the way.
Any help would be appreciated!
