Id love carpet...I miss onroad racing since I moved here. The cost of the carpet to cover our track area of 6000 square feet is more then the owners can afford. Its pretty tight there on money right now with us loosing racers all the time

Wow that looks very clean and sexy.

What 3 tracks are on carpet? Premier and RC Plus, but who else?

The indoor track at Santiam is still there; they raced some Friday nights over the winter/spring so among indoor tracks the split is 3/3. The key metric though is that, for example, a "small" night on carpet at RCP is 30%+ bigger than a "good" turnout on clay at NW these days. On Weds 5/20, Premier outdrew the outdoor track that was running on Saturday 5/23 even; something previously unheard of for an indoor track to do in the northern part of the state, regardless of surface, once outdoor season started.
We're a carpet state and that snowball is running downhill but that's probably enough highly regionalized surface discussion for now in here - there's a thread for that here: http://www.rctech.net/forum/electric...acks-us-6.html

Setup item some might want to try - if running with the L brace pulled as discussed a couple pages ago - try also pulling the gearbox spacer sheet. You get back some of the on-power rotation you lose from having pulled the brace, lower the cg slightly and around the rest of my setup on my particular track (carpet) at least, seem to carry a touch more corner speed.

I purchased a kit the other day and finished building the roller, but I have this part left over and can't see where I would have missed it, can someone please point me in the right direction?

It's in the back of the manual one of the last build pages. It's used to space back the rear tower on the transmission when running the shocks mounted on the back of the arms

Does anyone know how moving the rear linkage on the hub to the forward or aft holes will affect handling? I've read all the setup guides and google searched but never really found a good answer. Theres got to be a good enough reason for 6 holes
Thanks

Have you guys had any trouble with the plastic rear hubs? I want to try them on my bmax2, but someone told me they break easy.

All that matters is the length of the link. Forward or back on the hub doesn't change anything

Using small roll center spacers I have cracked them and caused them to bend. I use the 6mm wide ones (TLR,12r5, etc) with no problems since.

Thanks, I appreciate the help. I ordered a set. I'll make sure to use the larger spacers (I have some schumacher 6mm spacers).
