The gears in the diffs have never been an issue. Nobody has ever stripped out the plastic gears. You can't even compare the xb4 to a d413. The 413 is a sloppy mess! You should have gotten the yz4 to compare to the xb4. IMO no wheeler comes close to how well the xb4 performs. Now your going to need to get a xb2 while your at it.

They do hold up. I have them in my 2016 XB4 and have been racing it on very high bite astro and carpet 20K front and 10K rear. No issues whatsoever. I have something like 25 or 35 packs through it so far. I do have the metal gears and pins, but that is supposed to be more for inertia and feel landing off jumps.

Lets not get too far ahead of ourselves. I'm very happy with my AE cars. I even liked my b44.3 but got tired of carrying std hardware. People recommended both the D413 and the xb4. I'm ok at setting up a car and have friends that are pros. I'll let you know what I think after I run them both.

Yes, I agree. And with the 2015 version you can use shorty lipos so the car is not too heavy. Furthermore some teams like Losi or Durango drove cars in that configuration at the world championships in Japan this year, so also a Xray XB4 2WD will work very well on high grip surfaces.

So quick question...
When I land from jumps...particularly when I overshoot triples and land on the flat, My car bounces a lot and it's a 50/50 chance that I'll land on my wheels when it's all said and done. Can anyone make a setup suggestion? Here's more info on my setup:
Surface is short cut Astro-turf....med/high traction
60wt fr oil, 40wt rr oil, 1.7 x 2 pistons f+r, 4 dot front springs, 3 dot rear springs. Basically I kinda mimic the Coelho and Bayer astro-turf setups.

hate to double guess you but i run a 20 tooth pinion on my xb4 and have since the 14spec. 20/81 with the 81 spur gear being the stock one. so 20 seems alittle off being he is getting a 75 tooth spur????
but then again I guess it depends on what size motor. I run the orion r10.1 / Orion 6.5t combo

Hi Guys,
Need a favour - I race 4wd stock 17.5t in Australia its a reasonably popular class here. So weight is important. To compare the 4wd's on the market;
Could someone weigh there car - ideally as close to stock as possible with electronics and a shorty and body on.
Would be much appreciated? There is no prize for anyone who can post a reply the fastest. Thanks.

I'm running 17.5 .... One of the guys told me he couldn't get a FDR of 5.5.. So he got a 69 Associated and bore hole out...
they didn't have the 75 then..He now says that I can use a 75/ 33 pinion .. I need to know can I get a 33 pinion to mesh properly.

- Orion R10.1 ESC
- Trinity D4 17.5
- Savox 1251 Servo
- Futaba RX
- 40mm Fan on the motor
- Transponder
only thing that isnt stock is the Diff gears, ring and pinion i changed to Composite, but even at that weight on Low-Med grip clay it needs some added back into it unless you can get a setup to suit the conditions with a car as light as mine, in high grip it shouldnt be too bad
if the Ball diffs were used, it could possibly be under weight... not 100% sure

i also run the 75t spur, can confirm at 33 WILL fit, it just max's out the motor mount adjustment, but mesh's perfect. seems a 33 will be as far you could go with a 75 spur, it will give you a 5.68FDR, although i run 75/31 on our track here in Perth for a 6.04FDR
