i finished the kit not doing any of the recommended "mods" to it and do not have any problems with it so far, well except parts availability but there is nothing needing replacement yet.

wow you guys must have hands of steel to press those bearings into the axleTwo other guys had this issue in my area. Aside from the front driveshaft cup, all this kit needs is a center shaft that is 2mm shorter and all the problems will go away. With a shorter shaft, you can shim the bevel gear properly and still have enough play.

Everything else is based on your experience in building cars properly.

I'm hanging in there considering the times

Type3? Can't wait to see it if you are. Hopefully it's a full body car so that HPI can license it and make it for our cup racers

they are - and for Ray Murray's race we'll have at least one heat of them

the only questions are 1) will it be 27t/17.5 or 30t spec motors and 2) will we have enough registered to get trophies from the class (need at least 8 cars)

From what I remember, sounds like we'll have 5ish for Ray's race - just need a few more but I'm sure there there are a couple other 'lurking' around

It's rediculously difficult to install the bearings into the axle, and a couple of the toe-in adjustment inserts do NOT even go into the rear hub carrier.

Hands of steel? No, started the fit by hand but let tightening the wheel onto the hex do the rest of the work
I experienced the broken front cup though now. Bummed as it happened right before the main. Didn't even hit anything and have only been running a Mabuchi motor. I need to do some testing on this car so I think I have a good fix for it. I drilled some holes and inserted 1.5mm pins from an RC18T axle. 2 pins lined up well with the 3rd hole not quite right but I think 2 steel pins should be much much stronger then the plastic 'teeth'.
I hope HPI comes out with metal front cups and harder shock springs ASAP. The kit springs are too soft for high bite asphalt- way too much body roll.

Great fix! I'll try that on my broken one later too. Agree with the springs being too soft. The F201 spring is nice, but I need a more linear spring like the HPI silvers for the Pro4. Have this problem where the car oversteers on high speed or quick transition. Kinda acts like my M04. Going to try using some unconventional setups to get around this.

Hey guys...putting my cup racer together now. A question on the rear driveshaft cup: There are 3 short screws holding the "spur gear guard" on just behind the driveshaft cup....it seems like the back side of the cup might rub on these screws once assembled?? The screws are as close to flush as I can get them...
Thanks for any advice...

That's one of the reasons why I needed to shim the shaft cups. Don't over do it, or you'll lose the safety play of the center shaft and possibly destroy a bearing in an event of a crash.
