Drifting has different requirements than racing. You WANT the car to have a lot of torque so you're not worried about speed. Gearing for drifting could be around the 8.0 to 1 range depending on the track size. The shorter the track could use around 8.0/1. A longer track maybe go into the 7.5 range. For bashing with rubber tires you'll want to go down around 5.0 to 1 on a short track and 3.5 to 4.0 on longer. Really depends alot on track size. Try those ranges but CHECK MOTOR TEMPERATURE after about 3-5 minutes. For 17.5 BL racing I use the 108 64p spur with a 41t pinion to get around 5.0 ratio. If you dont know how to figure gear ratios heres the math for a xxxs. Spur gear tooth number divided by pinion tooth number X internal car gear ratio ( 1.83 for the xxxs) = final drive ratio. Hope that helps.
That was really helpful, although the post doesn't show up in the thread correctly. The only thing is that to get such a low ratio, I would need something close to a 50 tooth pinion. I'm not sure how I'd go about this since I'm pretty sure a 50t won't fit, and I don't know of any spurs other than the stock and the 108 and 128. Are there such smaller spurs I can use?

50t fits with a 108t spur fine, I think a 52t is limit.

I don't think you necessarily need a "shock rebuild kit" even though the parts that come with Losi A-5015 are essentially that, minus shafts, piston, and e-clips. I would think that'll do though since it is the screw on cartridge and o-rings. That might be all you need, anyone correct me if I'm wrong, I've never needed to do this yet. Found as "LOSA5015" in most places as the part number, by the way.

When mine start to leak, I just tear'em down, clean things real well and re-assemble with Associated 'Green Slime' coating the o-rings. Fill with quality silicone shock oil and you should not have to mess with them until you want to change viscosity for tuning.

Default Motor Sparks?

Alright. I took my xxx-s out for the first time. It ran great. However I did notice that whenever I ran the brushed motor in reverse, sparks would fly within the motor. There is no noticeable power loss but is there a problem here? Thanks.

No problem.
The brushes will "seat " in one direction so those little sparks are caused by the brush running on the opposite side to which it has set in.

Right now I am putting on the yellow (extra flex) belt and spool pads in the front. Let me say this, the car is a HUGE PAIN to work on as far as I can see. Any suggestions as how to seperate the front diff? I need the two driveshaft cups to seperate. I have been trying to unscrew it them (a screw goes through both and the gear) but that has been unsuccesful so far.

Hey Small, to take the diffs apart you need a flat head screw driver ( if it's still a screw and T nut set up) and anything that will fit into the out drive slot on the other side to hold it from moving, then just unscrew it. if it possibly stripped out the T nut then thats going to take some creative/ forcefull techniques to stop the nut from turning.
good luck with your car, and please re post if that doesnt help.

Thanks and the solution to losening the nut was to simply take the diff out of the chassis then loosen. I am about done rebuilding. I just don't enjoy all the parts that must be taken off. This was my first time trying to really wrench on the car. Next time it should be a sinch.

Hey Small, once you get familiar with the car you'll love how simple it is to work on, and how adjustable the car is, there is another forum the for XXXS and between the 2 you'll have more than enough info to make your car kill just about anything you putt it up against.
