 So I'm having a slight problem maybe someone knows how to fix it or at least stear me in the right direction.  Like I've said before I am a total n00b. 



I assembled this thing correctly and made sure the pin went into the notch of this little pinion? gear. 
Nonetheless any help would be a great help.

I doubt that the gears are supposed to be swapped around as this is a stock picture from redcats website. There was not an eclip but that might explain what is going on if it is the case that there should be one anyway. And yes I took it apart to replace the spur gear. I even watched the how to video. All I know is that this thing is about to get jb welded together if I don't figure something out lol

if an "E" clip is supposed to be there, then the shaft will have a slight indent or slit for the "E" clip to go onto. if there isnt one, then no "E" clip is to be used.

can u take a photo of your actual part? a couple differnt angles maybe? it might help us help you.

Status: offline 		uhhh I was wrong on that lol. Turns out there is definitely a groove for an eclip. So, I went and got a new one. It's all good now. Everything is staying together. However, I'm on to my next problem. My engine is running great... All of my drivecups are tight and drive shafts are good. Ive got a nice mesh with my spur gear. But when I give it the gas I've got next to nothing as far as speed is concerned. It does roll around at about a 2-5 mph pace but nothing more. If I pick it up off of the ground and go wheels spin like crazy. I think the slipper clutch might be too loose. How tight is this thing supposed to be?

I love it when im right. i figured an "E" clip was to blame. its easy to miss them sometimes since the gear can cover that slot if you arent looking for it.

OK, on to the next issue.

hold the truck on the ground, and give it alittle gas. see if your center driveshafts spin or not. if they do, then the problem is in your diffs or the output driveshafts.

If its revving high but not moving and the drive cups grub screws are tight its most likely your slipper, tighten down until snug then loosen a turn.
