Mini Sprint Hop-ups?

[Hypolito]

I just ordered a Mini Sprint. We are currently running on flat carpet. What hop-ups or spare parts would you suggest out of the box? When the weather turns, we will be running them outdoors on a dirt oval. The allowed hop-ups are any parts losi makes for the Sprint. Thanks.

The things I'd recommend off the bat are the Soft and Hard springs sets, Soft (LOSB1825) (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1825), and Hard (LOSB1827) (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1827), and the Aluminum Threaded Shock bodies - LOSB1115 (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1115). They make adjusting the shocks quite a bit easier than the standard clips that come with the car. Changing the springs on any location of the car, especially when running on carpet, is very noticeable.

The Double Disk slipper assembly, (LOSB1130) (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1130) may be beneficial, as well as Titanium turnbuckles, (LOSB1233) (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1233), though I have yet to see a stock steel turnbuckle break. The titanium turnbuckles are also available in pairs - Short 25mm (LOSB1234) (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1235), and Long 30mm (LOSB1235) (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1235).

There are also Aluminum spindles - LOSB1881 (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1881) and Front Carriers - LOSB1880 (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1880), Rear Hubs - LOSB1882 (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1882), and Zero Degree (LOSB1883) (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1883) and Three Degree (LOSB1884) (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1884) aluminum rear pivots, all as optional upgrades.

It sounds like our Carpet track is running essentially the same rules as yours; we can't change gearing, the servo, ESC, or brushed motors, and we run the large RR tires on both rears with no tire dope. The only difference between the "Stock" and "Modified" classes, are stock uses the Losi 1100mAh NiMH (http://www.losi.com/Products/Features.aspx?ProdId=LOSB1210) battery, and Modified uses the Dynamite 1650mAh LiPo (http://www.dynamiterc.com/Products/Default.aspx?ProdID=DYN1427). The difference in power just by going to the 25C LiPo is quite noticeable, about .3-.5/sec per lap.

We're getting anywhere from 40-65 entries per week between the 2 classes, I've uploaded a bunch of pix of cars here (http://s471.photobucket.com/albums/rr75/LJ_86/SprintCars%20Feb%202011/) and the track here (http://s471.photobucket.com/albums/rr75/LJ_86/SprintCars/). These cars are a lot of fun!

+1 To everything LJ said along with the addition of LOSB1248 (http://losi.com/Products/Features.aspx?ProdId=LOSB1248) MIP CVD set. This will correct the dogbone binding when your suspension is compressed.

SpaceGhost,
I have a question concerning the MIP CVD set. There is an aluminum shim that fits between the outside wheel bearing the axle pin. I cannot get the pin in the axle if the shim is used. Do you use the shim? I probably could force the pin in the axle, but it would not be very free.
Thanks

I do NOT use the shim.

OK, thanks......I'll get rid of the shim!

No problem.
