I have seen a few broken front arms on the xb4. It is not immune.

Yup, 2 race days, shredded the composite pinion, replaced it. Next race day, had to do it all over again. Found out if you replace one, replace them both. There was an issue with one tooth on the ring gear of rear diff, so replaced them both again.

Thanx again for your input
the 15' comes with the metal gears

The nice thing I liked about the xb4, was 4 screws, and your diff is out. real easy access.

Driven XB4 '14, D413 and B44.1

XB4 is by far my favourite. I've yet to put my ZX6 on the track so can't comment on that but the XB4 is well thought out. I have the steel diff crown + pinion in mine now so I'm a little less fussed about the slipper settings. With the steel gears, I drive my XB4 as hard as my D413, but the 413 still has a different driving style from the XB4 '14 because of the centre diff. XB4 has awesome parts availability in Hong Kong too!

Thank you for your time
It's true that a fast guy with most any car can still be fast. But I will say that a nicely built and thought out kit can make a decent driver, faster. Period.

Ive owned quite a few wheelers but the xb4 works best with my driving style. Parts can be expensive but the Kyosho cars are even more to start out and parts are almost just as much. I'm not sure how expensive HB parts are but the DEX410 was a nightmare to work on and I've heard it compared to that car in terms of maintenance. I'll never own the d413 as a result.

Sure parts can be expensive, sure parts will still break. But if something is twice the price and you break half as many, it's not really more expensive is it?

Has anyone used the RB Products ADS in their XB4? if so, how did you like it, what were the results?

Parts are expensive if you buy from a hobby shop. I buy most from eBay. Just picked up new front and rear shock towers for $25 shipped out of a 2015 kit.

Plus you finish races... I am sitting on a boat load of parts that I rarely ever need. Picked the habit of hoarding parts from my b44 days.

I don't own a xb4 but what size are the pins for the driveshaft? I would like to get one later this summer

First race night with the XB4 last night and it was the most fun I've had racing in a while. The car worked good but was a little loose in the rear on power. I had the motor turned down quite a bit, 50% at the beginning of the night and 70% at the end. The car and I both improved throughout the night and I got to within about a second per lap from the fast guys. A couple more weeks and I should be dialed in and competitive. How does everyone go about setting their slipper? I was thinking about when the slipper pads wear out to just get the gear diff since the replacement slipper pads are so expensive. But for now I'd like to get the slipper dialed in.

Set it the same way you would with a 2wd. Hold both rear tires on the pit table, and punch it. The front tires should only lift off the ground a little bit, and you should hear the slipper whine plenty.
