So stick with the 6.5 then.. The buggy doesnt have rear sway bars either. I bought it 2nd had so trying to dial in. I dont have the parts book so need to look up the parts. I know that the slipper right now is very tight with not much slip I dont think. 7/5 on the diffs. The pinion is 20 and motor seems warm for the little track. Thanks for all the input guys

this should you help you out for a manual:
http://www.petitrc.com/setup/xray/Se...tsXrayXB4.html

you really need to know whats on your car especially when you buy it 2nd hand. go through the car and redo the shocks, re-grease everything, redo the diffs (and since you are on low grip go 5f/2r).. and clean/re-oil the bearings. Also look at the VIK Tacoma set up and order parts that are needed.

AND CLEAN/ RESET THE SLIPPER CORRECTLY!!

Here's Tyler set up:
http://www.petitrc.com/setup/xray/se...acoma20140413/

That track is fairly tight - is that why he's running the 6* front hubs?

No rear weight?

TLR 42.5wt = AE 40wt-37.5wt = 500cst?
TLR 27.5wt = AE 27.5wt-25wt = 300cst?

6 degree hubs creates more stable low speed cornering. At high speeds these blocks reduce push as well. (stolen from exotek)

also the axle height helps:

Lowering the Axle (putting the shims on top of the steering block) will give the car more front grip entering corners, but a little less grip on exit.

no weight!

New to xray, I have been racing short course for a couple years and wanted a change. I picked up a xb4 for 150 and it came with some exotek upgrades. I am always for mods to cars so I gave the shorty lipo a chance and it came out pretty good. I ordered some spare parts like extra rings and pinions for diff's. I am not sure about the plastic in the diffs, are the aluminum upgrades for ring and pinion. Any input would help.

Aluminium crown and bevel gear are a nice to have if you can't be bothered to set your slipper clutch properly. As for the internal gears, I've been fine with the plastic ones and really it's nice that the drive train and rotational mass is lighter with the plastic than with aluminium ones.

I think my slipper was too tight all day. Buggy was very loose, especially the rear. Considering adding more rear toe and more rear wing. Is there a good method to setting the slipper? On the B44.2 you could push it gradually tighter until the front wheels would slip.

Over the stock pistons yes, I bought the 1.5+1.1's and 1.6+1.1's for outdoor (I found them ok, but for me they lacked pack). Check out Schelle, they offer the same pistons with the same tighter tolerances but in pairs of two, not four, like Avid, and they also offer 1.6 and 1.7 in a 2 hole piston - my next purchase.

Unfortunately neither make stock 1.3 x 3 hole or 1.4 x 2 hole for indoors/carpet. On another classified site there is a seller selling pistons CNC'd in Macau which are better than the Xray stock pistons (that are molded onto a plastic tree), but they are copied from Xray pistons, which means they too are just slightly smaller than they should be and wobble when in the shock body, much like the Xray stock pistons (disappointingly) do.

What kind of surface and tyres were you on? I'm on medium indoor loamy surface and I had completely the opposite with my XB using this setup - http://www.petitrc.com/setup/xray/se...un20130811.pdf

As for setting the slipper, I do that on the track. From a stand still, hard on the throttle and listen and watch the tyres. Slipper should slip and tyres shouldn't excessively wheel spin for about 5/6ft. Car should track straight and true. Once that's ok, I'll go around the circuit and make sure I'm not slipping too much for the take offs for my jumps. Its the first thing I check on the cars for the day that I'm running

We are running indoors med/high bite.. I ordered the 1.6 and 1.5 avids. Wasn't aware of the Schelle's till now.
