re west coast (my local track) how did the top 4 run 20 laps in the sat. points race? i could not be there...

I ran in the expert sc class...I have no idea?!? I didn't stick around to look at the race results...it was past midnight and I wanted to get home. I know TQ in my class was a 15 lapper...there's no way anyone went 20 laps in 5 minutes. Josh Newman went 16 laps in 4wd expert buggy and he was the fastest guy there...

A few people have posted this same problem...have you guys fixed it? Please let me know...thanks!

ThunderbirdJunkie's 1257 in his XXX-SCT is about 6 months old and is starting to have issues recentering, FWIW.

Thanks t-bird...maybe it is time to get a new servo. It's a hitec 5966 which they don't make anymore! :smile: Arrgggg...another $100 gone to the r/c gods :deathstar

Just did that and there is little to no movement on any of my cvd cup. the whole thing moves the amount between the barring and the pin

Should have specified, I'm talking about the diff cup/dog bone cup...

7940 is a good one:sneaky:
It ain't cheap...but well...it's not often ThunderbirdJunkie uses something of somebody else's and wishes he spent twice as much:lol:

Just make sure you buy a few extra HPI K4.6 backplate screws:lol:

So your diff cups don't move at all? ALL 4 of mine are moving up and down about 2mm? WTF?

This totally sounds like a servo issue. Get a Hitec :)

The problem is the shocks are sticking because of the crappy orings AE is
trying to run in the shock cartridge, plus some of the cartridges the holes
are to small or not round in shape.

The fix I found was to make sure the holes are round and the right size by
drilling or exacto knife. Then replace the bottom oring with an Ofna 1/8th
shock oring and replace the top oring with an SC10 2wd oring packing both
with RED Mobile 1 synthetic grease.

This makes shocks smooth and free in movement and they don't leak.

Hope this helps you & others"

Not sure if you realize this...but...in the steps where you're putting the bearings in, it tells you the size. You could've just like, opened the manual.

Your inability (or lack of desire) to help yourself is slightly unnerving.

Ooh, forgot to ask.

Never had an electric 4 wheel before. How do you set the slipper on this thing? The same way you would on a 2 wheel?

i believe it tells you in the manual how to set the slipper...

yup. page 28.

Again, anybody have feedback?? I have run into problems with my sc10 4wd...Mostly bc of user error, I think for running the truck without the two advised washers that go on the slipper assembly..I probably should have waited to put them on..Did you guys have the extra washers/shims that were recomended on this thread included in there kits??In running it, I think I destroyed my slipper thrust bearing due to the slipper thrust spacer not being machined right as noted b/f.....Well, i ran it without the spacers and needed to keep on tightening the slipper ( that everone says is the symptom of the mismanufactured part) and think i caused the slipper pads to burn out and destroy the slipper thrust bearing..The tranny is not binding as i free rolled it nicely..It also caused my 19t pulley to damage slightly..It's now a paper weight and feel bummed about it :cry:..I should have waited for the washers/spacers/shims/whatever you want to call them..:confused::mad:

I did build them both at Half Rebound just to start with, which is when I found the above issue.

I had one bladder that was mashed and deformed. I built my shocks emulsion style. I find it easier to build the shocks the same side to side emulsion style anyway.
