I hadn’t seen that.

I'm still waiting for some images of that conversion.

I have a bit of a problem, I recently installed my motor on my serpent and the pinion/gear grinds when I roll the car. Also what is a good size pinion to start with?

Are they new or used gears? Is the mesh set correctly? Gear selection has a lot to do with what motor you plan to run, so you'll have to tell us a little more info.

I have a 17.5 motor and the gears are used. I bought the car a few months ago. The pinion I have now was from a 1/10 associated buggy. The car rolls fine without the gear and pinion touching. Maybe I'm not using the right pinion.

OK, so a ballpark FDR for a 17.5 would be around 5.0, track and timing dependent. I'd start there and check motor temp after 3 minutes and go from there. Sometimes used gears just get loud especially if they are worn to any extent. I'm hoping your using the same pitch gears unless your using a Tamiya gear which has a slightly different pitch then the normal gears.

What is FDR? What size spur gear and pinion should I be running? I know it varies track to track, but what is a good starting point?

If you are running 64 pitch gears, it would be 40 pinion and 100 spur.
If you are running 48 pitch gears, it would be 32 pinion and 80 spur.

Almost all buggy gears are 48 pitch, not the common 64 pitch in touring cars. No amount of messing with gear mesh will work it that pitch is wrong.

Thanks for the help.

Hey guy’s,
what would you value 2 used 4x cars at with a bag of parts?
one has a lightened carbon chassi.

Lack of help in here in here??
does anyone come to this thread at all?

a friend of mine finally sold his for about $175.00

if anyone have 4x they what to sell hit me up.

Bought a project 4 and drove it around on driveway and I noticed the rear end was oily. Before I tear it apart, what area should I focus on? I didn't put this one together so I am not familiar with it. Is this normal?
