Maybe so. I was just commenting in reply to the other posters who wished for 12mm hex. I don't see that it matters other than 12mm hex is more popular.

I wasn't going to get one, but after looking through all the pictures my pre-order has been done!
Can't wait to build it

We were as frustrated as any customer waiting for the press release, but I am pretty impressed with the final presentation!

Thank you for the update Bryan, count me in for the 6th one claimed at Mikes!

The web site pictures show a 13.5T motor installed. To run that without changing the spur gear you'd need a 29T pinion, but I don't think that is going to fit.

Speaking of motors what motor/ESC are people thinking of running in this?

I wouldn't read to much in to it by the pics as far as the motor they had in for picture time. I run a 7.5t in my B44.1 and that's what I'll probably run in this buggy for my tracks.

I normally run a 6.5T in my 4wd buggies so that's probably what I'll go with in this one as well. I know it's a little overkill but I'd rather have too much power and be able to tune it out with the esc than to have not enough power.

I run a 13.5t so this is a concern for me kinda ..im I seeing that the diff gears are a composite material?
O and I like the 14mm hexes but not the 3mm shock towers

6.5T for me too.

And in regard to the 12mm vs 14mm hex debate - it looks like 14mm hexes are becoming more popular!! As soon as another major manufacturer jumps on board, they'll be more popular the 12mm!

you should compare lap times with a tamed down motor compared to a motor that is using its full potential throughout the track.

its like choking down a racing engine to meet class requirements or building one that produces the max power inside the guidelines.. which do you think will out preform?

i tested this. was surprised.

and now with modern ESC you can boost your motor when going with a higher turn (8.5~10.5 etc..)

boosted 8.5 in 4 wheel is the hot ticket!

6.5 is my personal go to in 4wheel.

Is it possible that a 6.5 with turned down boost(10%) will stay cooler and therefor last longer than a 10.5 boosted(40-60%)?
I ask because it would be great to have a motor for indoor and outdoor sized tracks.
Wiring in these tight areas is already an issue, i'd hate to rely on more than one motor a season.

Both win constantly at our track. A wheeler w/ 6.5 or 10.5 can do amazing things in the right hands.

normally you would run a smaller pinion on a boosted vs a non-boosted set up so the 10.5 should run cooler. With my Tekin RS Pro/gen 2 7.5T I run 40 degrees of boost after a 5 minute race I have 3-4 leds on the ESC and roughly 140 degrees on the motor. It runs cool for such a fast motor set up.

I wonder if the XB4 will bring any on-road XRAY drivers to off-road tracks that normally wouldn't run off-road ?
This could revitalize 4wd in areas where numbers are low.

You have a valid point, good driving can reduce the chances. However there's a very long way to go before this for most, myself included. (I am usually dead last after the first lap in any main regardless of my qualifying position, but almost always up on the podium in the end.)
And I doubt any company would release a car just for pros.
