i am the same as the other guy. on my 14 and 15 spec i went a whole year and didnt have to replace anything drivetran wise. in fact I used the center diff the whole time i had it with the 15spec and using it now with the 16spec and have not needed to even change the outdrives yet.

thanks for your work on this and bent aswell. so just so i am understanding this right, its both .75 xray hexs for the front and rear correct. and if i am understanding the chart right using the exotek hexs the fronts are close with 5mm but the rears with 7.5 are way off, about 3mm off right?? thanks again guys

I need some clarifications to proceed with my ordering for the XB4 16', because of the amount of options i guess. i'm coming from XB8 nitro.
1. I have read through the posts and noticed that motors talk are in "turns" and not in "KV". So, no brush-less motor is used? Is the brushed motor recommended?
What would be a fair brushed combo motor+ESC (and what turns?) and a fair brushless combo motor+ESC (and what KV)? Also please comment on "sensored" brushless motor.
2. What pinions i will need and how i will know that will be compatible with the center diff in terms of teeth compatibility? (narrow spacing tooth or wide spacing tooth?)
3. Battery setup? Shorty or long? What are the options and how to choose how to build?
4. Servo? Size? torque: kg/cm? Speed?
5. Is the 5-4-2 diffs ok?
6. What wheel hexes are recommended to have handy? 1,5 & 2 ?
7. What else i will need to complete ?
Thanks a lot!

You are supposed to measure the gap. I just used a 0.5mm TLR ballstud spacer and loosened until it just touched. Viola!

For 4WD modified go for a 6.5T. This will be good for both indoors and outdoors.
Regarding brands of motor and ESC you will get as many suggestions as there are drivers
What is your budget ?
2. For a 6.5T you will ned a 21 pinion for 540 size motor. They are 48P.
3. XB4 '16 only accepts a shorty battery. Choose a 4600mAh or larger capacity to give you some run time.
4. Any normal standard servo aimed at 1/10 buggy will do. Pick your favorite.
5. No. What surface do you run on ? For dirt and using the center diff go 5 / 500.000 / 3 as a start.
6. If using the standard 14mm wheels that come with the kit. None. Use the standard hexes. They will get you a long way.
7. The usual; paint, tires, radio gear and oils for diffs (8000cst is included in kit)
If running on low to medium traction dirt or clay we recommend to use these parts:
#361265 Medium side guards (hard is standard)
#361295 Medium rear chassis brace (hard is standard)
#361294 Medium front chassis brace (hard is standard)
#368284 1 dot rear springs
#368183 1 dot front springs
This transforms the car in terms of flex and mechanical grip and takes out the twitchiness it will have if you run the hard parts and stock springs on lower grip tracks.

That's what it's been designed for and what the team has been testing the last 1.5 years
We only run the small carbon steering brace connecting the steering posts, so we remove the front X-brace as well and run completely without top decks.
Much better handling and you can push the car much harder and it still stays very forgiving.
