Trips and Adam Lancia, Thanks for the answers I am not quite ready to invest in a new car but, need to make some minor repairs and this will do.

If you're running 4 cell Nimhs, you are already running 6V and should not need to run a receiver pack. The guys that are running 1S lipos are running those packs to increase the voltage.

Hey guys, I would like some basic direction help with getting started in 12th scale. I am a classic touring car guy, and have done it for many years (been out for a while, now getting back in) and would like to race 1/12th at the same time (outdoor med traction asphault), but am 100% (im talking... one hundred percent) ignorant to anythign and everything 12th scale /pancar.

I guess first thing is first, I need some direction on picking a car to run. Can anybody point me to a great kit? I need something competative, and something I can get parts for online pretty easily.

Iv heard of carpet knives? BMI something or other? L4 something or other?

Thanks for any advice/URLs you can provide.

Cpt.

Can Futaba Receivers, specifically the 603FS, directly handle a 7.4v 2s LiPo reciever battery without failure?

I am currently running the SMC 1-cell LiPo's in my 1/12 and WGT cars, but have been using the boosters or the receiver battery w/LiPo regulator.

What about the rest of the equipment too while we are on it, anyone know if these will burn out or fail from a 7.4v 2s LiPo receiver battery:

KO 949 Servo (1/12)
Futaba 9551 Servo (WGT)
AMB Transponder
LRP Sphere Comp '07
LRP SPX Stock Spec

I have emailed Futaba support, no answer yet, but I would rather get feedback from actual usage, not just an official Futaba answer.

We have people at our local track running lipo packs with some sucess. It takes a few weeks to pop a JR servo... However, people running KO and Futaba have no problems running at 7.4v. In GT I have a Fut 9651 with no problems on lipo Rx pack.

Capt'n,

Since the change to single cell lipo (at least here in the states) is going to happen sooner than later, I'd say get one of the chassis that will support Lipo out of the gate, like the Speed Merchant Rev.5. These cars will support both round cells (if you have to), and the latest in lipo tech, currently SMC is the only player in that market. Others will join soon.

Even MFGs that produce t-plate cars are getting ready to release cars that will support lipos. Several prototypes were seen at the ROAR nats, others were talked about, but were under blankets.

I am looking for the same information myself so I thought I would give it a bump!;)

Thanx Danny-b23 for u replay
i will try the 2,5mm chassis on a mid-grip carpet track

Well.. speedmerchant doesn't have anything on the Rev5 on their website... any other models / makes / links you can provide?

CRC gen x or the 12r5 thats my two choices.

How is the BMI 12r?

Excellent car, especially for asphalt.

One nice thing about 1/12th is that older cars are still extremely competitive as well. I'm still winning with a 12L4, though I did just pick up a GenX 12 in trade.

whats your opinion on 4c subc vs. 1c lipo? is there a signifigant voltage difference?

Yes but they don't use the same motors. I like 4 cell myself. The latest cells are performing great and my track hasn't gone lipo yet.

The Rev.5 information is available here. It was in a news release on their site. The news section seems to be more up to date than the 'cars' section.

Rumors say pretty soon there will be no round cells used at big events. This will also mean that the car weights will be re-adjusted with much lower weight minimums than what we have now. The rumors are somewhere between 720 - 740. Some tracks are getting around the mixing of batteries by allowing the people racing single cell lipo to use 13.5 motors race against the 17.5 round cells. At our local track we let the less experienced drivers mix in what they wanted for a while, for the summer points series we are forcing everyone to switch.

What your local track allows is up to them, however, by getting a link/spring car, like the Rev.5, you will be ready for the impending change when it does happen.

Good luck.
