Default Engine runs fine, the car won't move. Is my gear box set wrong?

Ok guys, so on my little Windhobby buggy, I stripped the large gear on it, and the replacement arrived yesterday. I changed it, but I'm still learning bits and pieces. After putting it all together, I started it up, and it started fine, however the buggy didn't move. It seemed to roll forward very slowly as I hit a higher RPM, I assume this was the vibration moving it forward though. The gears appeared to be moving fine.

I'm assuming the bearing on the large gear is a one way beaing, and I've got it on the wrong way or something? Will take pics if required.

Also, on the gear assembly consists of a metal wheel, small gear, large gear. What is the metal wheel? It has 2 nuts on it, one hold it to the gear axle thing, and I'm not sure what the other one does.

Does it have a slipper clutch setup at all? Maybe it's loose? Have you checked the clutch setup? I'm not familiar with the Wind Hobby Nitro stuff at all....I only have a few WH electrics that use a slipper clutch setup.

Ok guys, my assumptions were correct, the 1 way bearing was the wrong way around. Thanks for the help.

My buggy is just a HSP warhead ripoff. It runs like a beast though. I just did a few jumps in my small back yard, got a bit of air, and upon hitting the ground, I did 3-4 rolls, car was fine.

1 way bearing on the spur? weird, but atleast it wasnt a big issue lol. No buggy should break from a lil jump and tumple if so i wouldnt repair it lol i would sell it and move on. Now if your jumping wrong and break somthin thats a diffrent story lol.

Damn, a grub screw on the gearbox must have come out yesterday. Will buy some more I guess, but it was a rather important screw.
