I would use a 10.5 motor (local spec class)

Thanks for the help.

The bd7 is a great car on carpet. Carries a lot of corner speed. PM me if your interested in a BD7 with all the hopups and all the spares you would ever need.

The BD7 RS has some big disadvantages over the regular BD7.
Especially on carpet:
No anti roll bars, plastic spool, soft suspension parts and plastic shocks to name some of the main points.

Out of the box I would not recommend the BD7 RS for carpet at all, and hopping it up will be very costly.

So I think you would be better off buying a good used car. Many of them come with heaps of spares so you will save quite a few $$.

David

Thanks for the input, the anti-roll bars are a must apparently and I didn't know the spool was made of plastic. The club I'll run the car is carpet but everyone use rubber tires (we don't have a foam on carpet class here)

The plastic spool is very vulnerable, best upgrade would be the Spec R spool.

Anti roll bars would be recommended. Yokomo Pink / Blue springs also - the RS Kit ones are very soft.

Plastic shocks are ok. The plastic other components (bulkheads and hinge pin carriers) are ok but do introduce a lot more flex into the car compared to the BD7.

It would be a good starting point with the above spool, spring and roll bar upgrades.

Banzai Hobby has some of the best prices currently.

Aluminum chassis version

Open class version

Figure another $45ish for shipping to the USA. They are sometimes a bit "slow" (by the usual Japanese shop standards of nearly instantaneous shipping they take a day or sometimes 2) to ship.

Futaba RC Pro Shop is usually a bit cheaper on shipping though.

Very nice! Hopefully, they can put in a great effort at the Worlds and come away with a championship. It'll be a great way to cap off a wonderful season Ronald has been having. Not too mention, they can sell the limited 2014 IFMAR World Championship edition kits.

The JMRCA kit came with the alum chassis, short shocks, double joint units (newer clip on style), black central servo mount, ti turnbuckle, alum belt tension cam, ti coated main gear shaft, alum rear 44m dog bones, graphite bumper mount support. Pretty much everything you can buy now as hop ups are now standard.

Although the kit is advertised/marketed as a sport/stock chassis it comes with the 116T spur gear. Also, in the included special setup sheet it calls for the 2 blue o-rings and the thinner guide but the kit is supplied with the stock 1 clear o-ring and thicker guide. I ordered all of the necessary pieces for my shock and differential to get it working properly so it's not a big deal.

appreciate it. Banzai is where i buy alot of my stuff from, I was just checking to see you someone found it cheaper somewhere. I was trying to find a second car. I already have the black bd7 2014. i purchased the alum chassis, but dont have the short shock conversion. its a pain in the a$$ to convert everything over to the alum chassis, just to test. I prefer to have a second car ready.

Ran one my BD7 2014 in 17.5 last night, it's been a while since I put on the track but still super competitive without much adjustment I was able to come in third, off from .02 seconds, such a close race. The front two guys are better drivers but the yok performed amazing. I went back to standard shocks on carpet and it suits my driving better. I'm sure the short shocks may be better but I didn't have time to test it out again.

Its for High bite carpet tracks. The bd7 2014 has the tendency to traction roll due to it having a lot of mechanical grip. The carbon chassis is very good on asphalt and lower traction carpet. Hope this helps

The RS is very good value for money (actually I don't think you can beat it).

There are a few points worth mentioning, and yes, the front spool is one possible failure point, but you get two in the box, so hopefully you won't be high an dry should the undesirable happen. If your track has unforgiving boards, I am not sure what's worse, breaking a 5$ plastic spool or a 50$ driveshaft?

As for plastic shocks, etc, remember Xray cars come with plastic shocks and nobody thinks they're inferior.

Personally I bought mine as an RS and applied my personal touch to it by using everything available in my tool box before I went out and bought the expensive stuff. That's how my car ended up with Tamiya/Xray diffs (lowering the internal ratio is a bonus), an SD front spool (modified to be able to take Tamiya/Xray spool pulleys), Tamyia suspension blocks (much bigger range than Yokomo), Team Durango center pulleys, Xray belts, home made battery strap, Xray servo mount and so on. All of this stuff fits straight in, no need to drill, etc. The only bit I bought off Yokomo was a BD7 2014 motor mount (not really necessary, but good tuning option and quite cheap) which required drilling the chassis (no biggie). I also had to open up the diff cutouts in the chassis a tad for the Tamiya diff pulleys to fit.

You don't need to do any of that though. The car is very good the way it is, just don't hit stuff. All that plastic stuff means your car is more flexible so it should perform very well on carpet.

Could someone tell me the approximate length of the front camber link measuring from center of ball-stud to center of ball-stud? In the long and short positions.

Thanks
