just wondering what rear wing some of you are running are you just using the standard one ? the track i race on has a very fast main straight/burm and i was thinking of trying some thing with a bit more downforce to keep the car planted at speed i notice that the B44 has a 6.5" wide wing on it has any one tried one of these.

I run the stock xxx4 wing w/ out a wicker bill. I tend to like a car that generates a lot of corner rotation and it might seem a tad loose to some, but I try to get the car to sit on the rear and gain traction that way. I would only try a wicker bill or more agressive wing if it was really loose. Just my .02

hi just wondering if any one could tell me what sort of track ie surface etc you would use the losi BK BAR tires on and what advantages or disavantages they may have.Also what front tire would you run with these a taper pin?
i know it depends on a lot of other factors but just thought i would ask your opinions

we were using them on a drier indoor dirt track. normally we run slicks but, for some reason the track was drier than normal and the bk bars worked well.

the pucks on your slipper may be worn and need replacing .
i was having similar problems with mine even after replacing them etc the slipper would always need some adjusting during a race meeting so in the end i glued mine up so its solid since then it has not given me any more problems i have done 5 race meetings and 5 practise days with this set up and so far the diffs have not given me any problems i did pull the diffs down after the 3 meeting just to grease them but that was all .

dirt buggy,

Hi the pucks r brand new. The spur has a bit of wobble to it when I put them in. Dont know if this is causing the slipper to slip even though the nut if full locked. thx

my spur wobbled side to side as well, i have the kevlar gear, maybe when you put your pucks in your fingers had oil or something on them, or the slipper discs (metal parts) are badly glazed.

tater salad,

It is a brand new slipper assembly. New Spur, slipper hubs, pucks, top shaft bearings and pulley gear. Strange.

Matt, keep tightening it til it stops slippin, run it, tighten over and over.
Make sure the nut isn't slippin loose after you set it, mark it so you know it is stayin put.
They talked about it in this thread.
Watch out dude, I'm back

It only takes one run to toast your slipper pads in the XXX-4.... If you ran a few laps with this problem you might have glazed them.. once that happens you just have to replace them...
