that makes sense....just let us know how it works....if you have any questions about welding, don't hesitate to ask....I welded in high school and also in the Navy.....just practice on a scrap peice of metal, till you get a good feel of control for the spot weld.... and keep the amps mod. to a little high, but adj. accordingly..

I cut me a few pins out some good stuff. I tacked welded them in on both sides.
Ground a little excess off for weight. I noticed while welding the gears was on fire. Was these gears coated with something. I hope I didn't do wrong by heating them to much. I find out if they hold or if they wear out now.

Im not really sure what they where coated with CHC, But when I worked in a factory we used to oil heat treat the steel that needed to be extra hard, so I think if you cooked off some of the oil that might of been on it, you should be ok......I just recently oil heated my center shafts, for extra strength this week...and there is a slight residue on them ....even after iwipped them clean...so if they did some form of oil heat treat on them...then the oil penetrated the metal and will still be in there....does this help at all.......but thanks for the FYI about you welding the pin into place...

i don't know which size nail to use. the nail i have leaves some play between the shaft and the gear. is that normal?

The more play the more it will wear. I try to get them as tight as possible.

i'm trying to pound a hex wrench through it right now, its super tight. seems like its hung up on the shaft though.

If you have to pound it in. It should be tight enough.

its to tight. the hex just bent! this is really pissing me off! a $1500 truck that i can't keep running. i might have to go to nitro like my friends!

Jhonny maxxima, yes hex alen keys are very durrable, and should never snap on you. I thought know one would have knew:027: :005:

Sacrilege! :dft002:

More like blasphemy!!

It is frustarting some days. You get nitro it won't break as much cause it may not start every time. :D
Besides it don't have the same torque curve. I used a drill bit I had laying around that I broke off. I can't recall the size. I used a hardened rod in the other. It is holding well so far. If you take the points off the hex it may fit a little tighter.

Yea, I here ya about going back to nitro...I am selling mine cause I'm sick of the bull$hit. Just gonna spend the money from that on the electric truck to make it even better :D.

i got it up and running! used a hex wrench and beat on it for 20 minutes, i think its tight enough now! its funny, two of my friends just got into nitro and are learning to drive a lightning pro rtr and a hellfire rtr. thats why i'm thinking of doing nitro. for racing its a blast with my friends. i'll probably grab another crt rtr, got one in my living room waiting for brushless.

don't hate me to bad. i might need an exorcism because i bought a nitro today, lol. my friends were having to much fun without me. no worries though, i still have my g2r and my soon to be brushless crt project.:032:
