proline pro trac ????

[kspec4]

hey all, got the proline pro trac with the mip x-long male bones....now it seems like my pede is really tight. you cant just push it and it roll smoothly now. a little bit about it real quick...started out life as a p4de, did the slash chassis conversion and also has the mmp with the 2400kv. it did fine till i did the pro trac upgrade...now it just seems tight. any suggestions...thanks in advance

Check a few things: with the truck up on a stand do the individual tires rotate smoothly?

Does the problem get worse when the suspension flexes?

Is the camber off with the protrac setup?

What caster blocks are you using? I know a lot of guys including myself had to take a little metal off the casters or off the dog bones because they were rubbing. I would check that. Also when you add the protrac you have to get different male bones for the extra length.

My bad I just saw where you have the different bones. Long day.

seems like it is worse when the suspension is all the way down, like in a jump in mid air. as far as my casters go they are factory up front and rpm hub carriers in the rear. I didn't grease the mips like it says to, but I never did my orginal set either and never had this issue. maybe I'll try some grease tomorrow and see if that helps. just took it and rolled it on the ground also, still seems a little tight, especially when I pickup it up and let the suspension decompress, that's when it's the worse.

ill have to take a pic and show you wherer i found a binding point. Digger ran into the same problem and did a similar fix.

[kspec4]

cool i would really appreciate it

[BAMAFAN]

it will be after i get home tonight from work.

You can't tell where I did the work without tearing apart. Are you still having trouble?

[kspec4]

thats cool, yea its still doing it, this one has me stumped

I had to grind away a little bit on the inside of the front STRC aluminum steering blocks. It was a very minoot amount of meat from them. I grinded enough around to where they didnt bind at any angle. Being yours are plastic and if this is where they are binding you can take an Exacto knife and cut away until it doesnt rub. I believe Traxxas ones have the same issue to. I was lucky and the rear bearing carriers didnt catch.

Another thing be sure you have the pin centered, the one that goes through the sleeve as best as you can. I know when i hunkered them down and i didnt hold force the grub screw would move the pin up a little. Using a pair of channel locks over them would work well to.

Hope this helps.

Thanks Digger for clarifying!!!
