Default MIP CVDs

i put mip shiny cvds on my rc10t3 yesterday, but i have a question i couldn't find the answer for on their website or in the instructions. how tight is the set screw supposed to be? if i put it too tight it seems to hinder the motion of the cvd, but i don't want it loose cuz i thought it was supposed to hold the pin in? so how tight? right now i tightened til i could feel the cvd motion get stiff then backed it out a little.

thanks.

I tighten it tight and use lock tight, it shouldnt make the cvd tighten up (if thats what hinder means) .

i'm looking at the robinson racing 48p 19T/20T absolute pinion and a 48p 87T absolute spur gear for my truck.

any opinions?

Loctite it and snug it down fairly tight. If you don't it will come loose and the pin will fall out and may damage the CVD.

By tightening the screw it should not efect the movement of the CVD. If it does you may need to look another problem.

okay. i assembled the cvds as instructed, they just don't turn as freely (before putting them on the truck) when i tighten that screw. perhaps the pin is tight on whatever part needs it to turn freely or whatever.

i'll lock them back down again tonight and run it a bit.

Check for flash on the small metal CVD parts, and file it down - I had a problem on a pro 3 cvd where one of the parts was badly finished, and it locked up the CVD.

it's not locked up. i redid them last night, they don't turn quite as loose but they also don't make any clicking sounds now. i'll check the parts again but they looked okay, altho the pins didn't slide in loose to the bones, i had to push them thru with needle nose pliers.

robinson has lots of neat toys for the truck, someone please take away my credit card before i do anymore damage.

also add some big shrink wrap around the cvd where the pin is, this will keep the pin in if the set screw dose come lose.

i've seen some other that had silicone boots, was gonna try and hunt down some, but the shrink wrap idea sounds like it would work too.

make sure the round part that fits in the bone spins freely, usually I end up sanding it down a bit to get a nice fit. Use only a tiny amount of locktight on the setscrew or it will get inside and bind up the movement and tighten it down as hard as you can. Or just run them the way you have it and it should loosen up on its own.

the best thing to do is to file down a flat spot in the cvd pin so that the set-screw has a place to fit in. When the CVD pin is round, it presses a flat set screw against a round pin and doesnt put a lot of pressure on it. Be sure to use loctite as well.

am too running mip cvds on my practice buggy, the mp6 int'l.
you gotta to tighten the set screw tight. otherwise the pin would fall out. it happened to me just this last weekend. fortunatelly, i got a used hpi pro2 shock shaft, cut it in half and was a perfect fit into the mip.
i was considering of getting back to the old mp6 setup, using the universals....less maintenance.
