I'm looking at getting into 1/12 onroad after racing oval pancars for the last 5 years. Trying to figure out what I need to get, right now it's between the Associated 12R5.1 and the CRC Gen XL. I'm going to start out in the 17.5 Single Cell class, so any advice on gearing, tires, cars, and bodies would be appreciated.
Thanks in advance Michael

THAT BATTERY CALLS FOR CHARGING IN A 2CELL MODE AT 10.6 AMPS? is that safe? and would that icharger u sell there be able to do that. i currentlly use the cheap ice charger, as im new to lipo, time to step it up now...

2C stands for 2 times the capacity, in other words 10.6 Amps. (On a 1 cell (1s) charging program ofcourse)

Depends on which ESC you have! When I downloaded the new Tekin RS software, I dropped 8 teeth on my pinion, after increasing my spur by 12 teeth! (was 72/44, now 84/36)! That's on a 100 x 60 track.

I'll be running LRP SXX.

The Ice charger won't have a problem with the 5300 battery - the 2C rating means that it can be charged safely at charging rates up to 10.6 amps. However, you must set the charging profile for 3.7 volts, not 7.4; otherwise, your new battery will never see the track.

No problem here with 9602s, but a friend couldn't stop his glitching! If you haven't bought the receiver pack yet, and you have a LiFe compatible charger, then get a LiFe receiver pack, as they are 6.6v, and less likely to cause problems.

If you already have the pack, then consider a regulator if you have any problems. There doesn't seem to be any rhyme or reason why some people have no problems, and others do. HTH :)

OK,SO WITH THE ICE I CAN SET IT AT 2C and get the 10.6...but again setting at 3.7 volts...what does this do charges faster? better performance as well?

Yes, it charges faster, with the downside of reducing the lifespan versus charging at 1C (5.3A). 3.7volts is the voltage of the 1s pack. The ICE won't allow you to charge at 2C if you have the voltage set correctly (1s LiPo).

Don't try to trick the ICE just to charge a little bit faster, or you'll smoke your 1s pack.

The Ice charger can be set to charge @ rates up to and including 8 amps, but the recommended charging rate for a 5300 MaH pack is 5.3 amps.:nod:

Thats what i thought, and how i previouslly been rule of thumb charging, but i keep seeing this amped up rate, and besides charging faster, i want to know if there are any performance gains to be had. TQ racing recommends, rc market had it posted, so most likely smc even recommends it? Cause if it were to gain in performance, id sacriface some lifetime of the pack, for more performance, and id have to buy that icharger, as the ice is not capable as stated..

oeoeo327 01-14-2010 10:50 AM

The only gain you'll see might be more track time due to decreased charging times. However, the downside is a decrease in the pack's lifespan. There are no performance gains associated with increased charging rates.

Cool thanks, you just saved me some money on a new charger, and a possible smoked pack, ive been playing it safe doing the 4.9 charge rate with the older 4900 mah with no problems, just after seeing that wanted to make sure i was up to speed, but after your guys help, i see no reason to do it. THANKS GUYS!!!
