XRAY - Model racing cars

These XB8 Build tips are from a forum earlier this year, do they still apply or has XRAY made updates....

- DON'T bother to install the small o-rings that go into the bevel gears in the diffs. Most MBX5 owners also don't put them in.
- The best diff oil setup for US Tracks seem to be 5K/7K/1K without o-rings.
- The XB8 REQUIRES droop screws properly set or else you'll break shock pistons or get binding on the rear outdrives. USE THEM!
- When installing the shock boots on the rear shocks. Make sure they have enough travel at full extention so they won't RIP apart.
- The body shell holes for both the mounting and engine hole are NOT accurate. Put the shell on the buggy first before making holes.
- Start off with 1.0 clutch springs (not .9).
- Put a dab of super glue on the rear of the flywheel where the pins go through.
- Engine alignment is more critical on the XB8 than other buggies, best to remove the fuel tank when doing this.
- Even when you're still building, cycle the included RX battery to make sure you don't get a DUD.
- DON'T use the included muffler hanger. It's way too rigid and might deform your muffler. Use bicycle spokes or piano wire.

If you follow the above, I'm sure you'll avoid the problems most of us pioneer owners experienced.

***Also remember that some have tightened the nut that holds on the piston too tight and caused the piston to break.***

I also believe the loose flywheel pins were a single occurance thing.
I've had no problems with mine.

You might want to add, the front droop mod as an extra tip.
The rest of the list is pretty accurate though

What's the stock shock oil & wt. that comes with the kit. Mine will be here tomorrow and I want to have extra of the stock.

I have some open bottles of 55 & 40 wt around the house but not full bottles.

Thanks all

the kits are supplied with 350 shock oil
well mine was anyway!
check you've got the latest kit with the white shock pistons too
