Hi, just picked up a 2015 XB4 and started the build. Its my first time with a 1/10th electric.

Just wanted to know from the people here who are more experienced whether there is a handling and performance difference between the Saddle Pack setup or the Shorty pack setup. Does it change the handling of the car in anyway. I do have Shorty Packs so i was thinking of doing that setup, but i need a car that can handle more of a loose (low bite) track that we have here locally.


Thanks for any info or advice anyone can give.

Thanks Maricopa i will try those changes tomorrow and let you know if they worked for me. Randy - i have a 14' and AMS is where it drove poorly and the track was amazing. The setup change i spoke of was different springs, sway bars and pills...which cost more than i imagined. Any Michiganders have tire suggestions for Ams and Clubhouse? I'm currently running suburbs in rear and ions up front both super soft. I heard tendroids were the go to for Clubhouse.

yeah at AMS Ions will work if its a new track layout or if the track in moist or wet. as for normally I run Panters Rattlers 2.0 with Bobcats upfront.

I have a '14 XB4 and I love it. It is completely dialed and I have 100% confidence in it. However, I was looking at the 2wd buggy and I've had a couple of Xray drivers say it's really designed for astroturf, carpet, high grip tracks and wouldn't do well at the track where I race (hard pack moist clay). So my question(s) are, if the 2wd and 4wd share so many of the same parts and seem to be built the same, why wouldn't the 2wd do just as well? The next question is if the 2wd will not do well, what about it makes such a huge difference? I really like that the platforms are so compatible but I don't want a 2wd that is not gong to be competitive.

Thanks all.

I think there is a new 2wd on the way from XRAY if you read the news at XRAY you can see that mr. Hudy and Bayer is driving a new 2wd

My '13 has always done this as well, no worries.

I believe its because the weight bias is so far forward, there isn't enough weight over the rear tyres to get traction. Even their team drivers who are running on carpet are modding their chassis to run a shorty and put the motor in the rear to shift more weight back.

I'm using a few different shorty packs. I have an SMC 4400 Mah 60C, a Turnigy NanoTech A-Spec 4200 Mah 65c, and a TrakPower 4600 Mah 80c.

The rims are all the same for the 2013, 2013v2, 2014 and 2015 spec cars, so yes you can use the 13 wheels on the 15 car.

All rims fit but the v2 fronts supplied with the 2014&2015 cars are different. Front offset is +1mm. They'll all fit but don't mix them up.

Got me a 15 kit coming. Pretty stoked about it. Any pointers for the build process? I'll be putting AE fluid in it so I know what I'm dealing with. What's the stock fluid setup? Thanks in advance.

It is a combination of weight placement too far forward and not having the front wheels to pull the car for the rear end to follow.
