What are you guys running @ your home track on a weekly basis? What do you think about the classes offered?

We are running 95% brushless 4-cell, but we had one of our racers badly injured by an exploding cell NIMH. I have been testing a lipo 21.5 and so far it has worked great. I think that the speed will eventually be about the same as 13.5 4-cell, right now I'm about 1 lap off.


Several of our racers are looking very seriously at the lipo deal, for safety and ease of operation, by biggest concern is the racers themselves, if they are handled according to the the instructions that come with the batteries, I think that they will endup being safer than the exploding cells that are currently out there.

the tri clone has a few guys trying the lipo and 21.5 with teh same results very close if not even with the 13.5 guys. I have to admit I like the one battery all day thought

I've been running 21.5 / LiPo for a couple weeks now along with the 13.5 cars - I ran within a couple seconds of the TQ 13.5 4-cell car last time at Triclone. I ** LOVE ** LiPo !! This coming weekend, there is a BRL race at Triclone, so we're running the 21.5 LiPo cars in their own class -- I think we'll have 3-4 cars. But we have several more drivers that have said they will switch to LiPo for sure for the outdoor season.

We are running 95% Lipo/brushless we started out with 17.5 lipo now the 21.5 lipo class is catching on. I would have to say that by far the lipo is the way to go.

we are running the cot 21.5 lipo my track record is exactly 1 lap faster than the fastest stock 4cell record! the 3200 orion lipo pack is awesome!

17.5/lipo or 21.5/lipo with a nitro class like .12, or .09 would be a great race schedule maybe a 21.5/lipo with some restrictions like a spec class would be great. I know that most tracks offer a spec class that runs spec motors and batts, but if we could come up with a brushless/lipo class that was slow enough to run spec speeds I think that would be good for the new racer. It would let them get use to the brushless/lipo deal, and allow them to learn more about chassis setup rather than getting the brushed motors to run, and buying batteries every month. Besides when the new racer wants to move up they would already have the charger and batt to step up to the next level. Just my .02. Im by far no expert!

Good guys, keep um coming! I thought more folks would hang on to the NIMH batteries with brushless. I still love to race, I just don't have the prep time anymore. Even my chassis get's neglected sometimes so not having to build my packs or motors makes it easier for me to still race and keep up with all of my other obligations.

I have been playing with a lipo 10.5. It is wicked fast.

i think that brushless and lipo are the combo. but what will be the milli amp to get, are they going to run smaller milli amps to keep the speeds the same. i also have tried 10.5 with a 4800 lipo and it's insane. it's just the way to plug and play.

At our track in S. Sioux City, Nebraska we are about as close to 100% Lipo/Brushless (oval) as you can get. I have run the 21.5 /lipo and I personally would favor that class but Brushless 17.5/lipo is the most popular here at this time. Last couple of weeks we had only one driver run a 4 cell pack/10.5 with us but he was going back and forth during the day between his 4 cell pack/10.5 and 17.5/lipo. If you like the concept of brushless racing then you have to like lipo racing. If you have'nt given it a try yet you should. Plus by next racing season the lithium-ion batteries will be readily available( coming in March 2008) for R/C and we are being told by the supplier that these are much much safer than even the lithium-p. and both are safer then the sub-c cells. The change to lipo, whether lipo or Lithium-ion, IMO should be done as quickly as possible.

I second that. Any battery can be dangerous but IMO lipo is much safer!

I'm sure at the X-treme Cellar Race track there will be both by next season Lipo and still Nimh

my 21.5 Lipo car is running .1 to .2 seconds slower a lap then some of the best 10.5 4 cell cars in the Country at Stricklands RC in Daytona Florida (Run line 160 feet) and About .3 seconds slower a lap then the same guys at Hobby World in Jacksonville Florida (Run line 380 feet) Im also faster then the 13.5 class with my 21.5 lipo car by about .2 seconds a lap on both tracks.

Can you run all day on one pak? How many should I buy?:o

1 Pack all day is all you need. The Packs get better the more you charge them. The 3rd and 4th charge on a Pack seem to see the best of the day.

Thanks!:)

I cant believe oval guys arent eating the a123 cells up they have a 3.3v nominal voltage so a little less then li-po's however they charge at a 4c rate 15 minute charge's that is by manufactures spec's to by the way no crazy battery voodoo. another nice feature is they are safe down to 1v unlike li-po's, and wait there's more the are in a aluminum case so a inpact is not a big issue unlike li-po. just another battery option to throw out there. I think allot of the li-ion talk is actually about these cells. i love li-po's but a123 cells have caught my eye i think they will catch on.

I have wondered the same thing about the 123 cells. I really thought those would be an attractive option for R/C racers

my biggest thinking is oval the voltage of a li-po is kinda high for most tracks with brushless so people are trying to get slower and slower motors' lower voltage would be a key here.
