I can just ask Steve Sobottka from this past IIC...he had a pack go up on him ON THE TRACK! 4200's are dangerous man.

And packs are pretty regularially available now above that too! Main thing is with LiPo it runs the same charge after charger, they don't blow the casing off like a shot gun shell, and you don't need all these discharger, balancers, and equilizers! On Off-Road, my car actually handles better and reacts quicker with my LiPo practice pack than the bricks I have to run. And Jeff, if you buy 1 LiPo and a LiPo charger, you can replace 6 Sub-C packs easily. Plus you can get a GOOD LiPo Charger for $45! I can't wait for LiPo's to be more readily accepted!
I was just talking in terms of having to buy new electronics, I realize that the voltage wars rage with the traditional cells. I love not taking all the crap to the track to maintain NiMh packs, and not having to wait for batteries to peak is even better

My car ballances much better (TA05) with aOrion 4800 than it ever did with NIMH cells...I am only off 10 grams (light) on the battery side. My car works flawlessly run after run with NO upset from the lightness.

And the cost factor is silly...lets see a GFX-$380...4 good packs of IB4200s-$160-200..(which if your lucky will be competitive for 2-3 months)...a cell equallizer $40-50..so now we are around $600-$650...$200 of which will be junk in a couple months. Lipos...Charger-$70-$125 depending on charger...and 1 Lipo pack....good for over 1000 charges with NO loss in performance! $75-$140 depending on either the 3200 or 4800. So now were at $260 on the high end with NO equiptment needed and you will have charge after charge after charge with no loss in performance and no maintenance....yeah, it's a tough choice.

Myself and several others from my area passed on the TCS series this year because we didn't want to buy $200 in batteries that would be junk in 8 weeks! I think Tamiya NEEDS to make them legal in all classes to keep the TCS numbers growing.

If most of the local tracks were running Lipo's that would be another story. I understand the logic of Lipo's, it just would be bad timing to go full bore into them. Maybe 3 to 5 years would be more realistic. . .

I'm headed to the TCS race in Memphis this weekend. Anyone willing to share their asphalt parking lot set-up for a TA05 with me.

Hi Guys. I updated the website with some new Fun Race details. In the interest of experimentation I am allowing the guys in 19T (GT-1) and GT-2 to run the Novak 10.5 and 13.5 motors respectively. Sine we are trying Lipo's for all classes to see what's what it will be just as interesting to see the brushless factor.

As far as the Lipo debate, I see both sides of the coin. Personally, as a racer (when time permits ) I hate what I've been seeing going on with all the I.B/E.B. GP whatever battery wars. There's way too much VODOO magic to those things, but it's been that way forever, but worse today so it seems. At last year's KO GP I had so much fun running the one LIPO I had. That battery today is as fast now as it was 7 months ago. Right now I'm trying to help some guys prepare for the Reedy Race and all my battery stuff is junk. Good enough for practice, but it's slow

Anyway, for next year I am going to introduce a new class that I'm sure some will like and others may find ways to debate it. It's really simple and it should prove to be interesting to see what people end up spending their hobby race dollars on for next year. Thinking out loud it will be called Formula GT. It will be very spec. Orion 3200 or 4800 Lipo's, Novak 13.5 brushless motors. TA-05 Chassis cars. 8 minute racing. We'll see what happens.......

Fred,

This will be very interesting to see this weekend.

IB with brush
IB with brushless
Lipo with brush ( me )
Lipo with brushless

And I like the Formula GT idea.

Chris,

How much time you need to top up the 3200 in between race for 19T with the Orion charger. Charging at 1C or how many amps ?

Seriously - sounds like a fun day. Enough fun to cancel two hockey games. GT-1 Reedy Spec for me.

Formula GT...... wheres the sign up sheet !

hopefully Mr.Black will correct me or the other "experienced" Lipo guys... but it takes about 40 mins to get it to 8v. once at 8v you can run the pack. it starts to slowly drop the charge amps until it tops off at 8.4v.

btw.. back in november, i raced back to back 19T qualifiers with one 4800 lipo. (sportsman then pro 19T at La mirada, long story why i was in two different quals)... ZERO fade. it was strong from minute one to the 10min. and this was a borrowed pack from Ling.

GT class sounds like fun Fred. count me in.
