gear problems
I am running diffs, front & rear. My
car has been punted, whacked, done
cartwheels down the back straight and
NO dusted gears.
WHEW!
My cars problem is the rear, left,
upper/inner ball-cup. Four times it
popped off (in action). Three
times lost the out-drive saver, four
times "dnf". PRM's are a tad tight on
the balls, but I'll try "working them"
in.

KevinK,
How is the car running? I posted the set up I had been running. I am trying new things each week. The BMI 3mm conversion made a big difference.................... Hope all is well bro!

Wll I started building my car lst night. So far it is a pleasure to build. No having to reem parts or anything like that to get a nice fit. Screws are no problem to put in if you have a nice 2mm ball driver ( I have a nice Thorp/MIP) so it has been easy. Overally quality is top notch so far. I'm going to build the diff right now and start putting the rear diff in and rear gear covers.
My new BMI chassis will be here early next week. Will switxch over to that chassis setup for next week. It will give me a chance to see what differances I see between the two setups.

pops, when my dad picked up my pro4 today he was told to lightly sand the edges of the gear box case things until they sit nicely
if yours are maybe a bit off it may make your upper deck not sit right making you have a lot of tweak.
so maybe try sanding the edges.
also, i haven't built much of mine but its going together nicely

One tip! If you are using a tap for the droop screw holes, only put it in about 1/4 of the way. You want to droop screws to be tight, not loose.

Yup! I made the mistake of fully tapping one of my arms before I realized my mistake... at least I'll only have to be constantly checking ONE arm.

Im glad you joined the wagon. I'm loving mine, I'm wating on a BMI chassis myself so I can do some more testing. Ill probably get to run the car more in the next few weelks. Inventory at a shop is no Joke! specially when you cary as much stuff as we do.
Ray
what's up brother, call me at the shop if you need parts. I sent Eric a care package the other day.
