Default XB4 Spur Cover

Anyone made or modified something to cover the spur gear. it sits pretty high up and worried about a cable rubbing against the gear.

pics if you have done anything

Thanks

You should have no issues at all as long as you run and secure your wiring well.

I run my positive and negative wires underneath the front top deck on my 15 under the brace connected to the front chassis brace.

You could do that my friend. Most put the ESC up front to offset, balance the weight on the front end. Servo balanced out with the ESC on the opposite side.

Also the balanced front weight helps obtain steering.

Again you could layout your electronics as seen in your diagram. If so I would add weight by the receiver thus to offset the weight of the servo on the opposite.

Thus a balanced front end.

Anyone know where I can find the rear brace to make the 2016 XB4 stiffer? Been looking everywhere but no luck.

XRAY XB4 2016 2.0mm Graphite Chassis Brace/Upper Deck (XRA361178).

I know it's an optional part but I feel like it would greatly improve handling on high bite surfaces.

The XRAY-Shop Austria has them. If not they usually always re-stock parts within 7-10 days. Shipping is pretty quick being 7-10days. You have to sign in/create an account, thus you will see the prices with out the VAT. Their parts are cheaper than purchasing in the States, however when you add shipping it pretty much equals out. Great place to go if you cant find parts in the States.

I'm sure you all are tired of this question...but here it goes...

What gearing should I start with for an XB4-16 running an 8.5 turn motor for a medium size/medium grip dirt track?

Just picked up my XB4-16 this evening!!

Quick question....

Finishing up my XB4 2016 and am at a loss of what to do about the center diff. No real experience with gear diffs so this is new to me...

I have been told/read to use everything from 50K to 120k to 1.000.000 in the center diff. Any suggestions where to start on high bite clay running slicks?

Thanks,

Aaron
