What do you guys think would be more comparable to the 4cell 13.5 combo, lipo 17.5 or 21.5? From what I hear SMC and Max Amps are working on hard cased saddle packs. Track power makes one, but it is way tall.

Most of the guys running lipo have found that the cars don't handle until they weight the car up to the 6 cell level, which makes my 4 cell car pretty competetive. Same goes for the mini, it will handle better with a bunch of lead on the bottom of the pack! Why do I know this? I'm not telling!!

Our series here is really fun, with the GTP and GT running together. It's like the American LeMans series, with the 6 cell/lipo cars as P1 and 4 cell as P2.
OD, our club is looking to do something similar this winter on the carpet. I as well like the idea of the 4 cell as I have them for my 1/12 scale, Vintage Trans-Am and Now GT.

I also have used a lipo in a Darkside 200mm car with a 10.5 and lets say not as much weight as the 6 cell pack, and the car while very fast was not really drivable.

PS Nice 10L3!!

The Oval guys here have a lipo 21.5 class, they say its about like 27t, but I've never run any of the combos you mentioned. You guys will have to try them and see! My guess would be lipo 17.5 would be the closest, but maybe too fast to run with 4 cell 13.5

I don't think the whole LeMans concept occured to the people re-introducing the pan cars, but it sure is fun. I've never been a big fan of emulating full size racing, but its cool to see all the cars on the track together, and when the 200mm GT car wins overall...Priceless!!

Audi can't compete with Peugeot for speed, that's a matter of fact.

The only question is, are 908s reliable enough to make it in a 24 hours race ?

I hope so, as i'm french (nobody's perfect ...).

Thanks for your thoughts OD. That's what I have been afraid of that 17.5 lipo would be faster and 21.5 would be slower than 13.5 4cell. I guess probably we will try 17.5 and it it is fairly close maybe implement a fdr rule or something.

Hey JCarr, it's Troy. After reading a lot on this thread and the CRC Battle Axe/Gen X10 thread I'm ready to take the plunge into pan cars!! So, do you think 17.5/Lipo is the way to go? Any one else at THS going to join us?

Novak has an 18.5 too if I recall. Would that be closer?

Why not run this as a voltage class? Have basically two classes - 4.8v and 7.4v - and let people choose their own motors? It seems to me that to make this fun it has to be as open as possible.

These cars won't handle well if the weight in the cells gets to be below that of a 4-cell pack (the BMI car takes LiPo but uses a weighted cover to equal the weight of a 4-cell pack, and goes great) so those running LiPo will be at a disadvantage if they run too light.

The motor issue is self-regulating. So-called slower motors will only lose out in a straight line. On the infield, the limiting factor is the grip, so there is a limit to the power one can use. It might be full throttle on a 13.5, and half throttle on a 6.5 (for example) but if the car isn't set up properly, no amount of power will make up the difference. A well set-up 13.5 on four NiMh will kill a 7.4v LiPo 17.5 on the corners, even it loses a bit on the straights - rather like the real thing really!

The essential thing is to keep the bodies real. HPI and Tamiya shells are the best, so stick to them, paint 'em up well and sticker them like the real thing. That's what gets the drivers in!

Let's not sweat it. LMP1 and 2 is 7.4v, and GT1 and GT2 is 4.8v. Then run whatever motor you can handle and makes your driving fun - isn't it that simple? Isn't this the way to open up the class and allow everyone to come in and enjoy themselves?

We talk about it too much, better to JFDI - just do it!

Default roar and or ifmar

hey all: Will the gt10 or worlds gt class what ever they are calling it now be added to the roar nats. and or ifmar worlds race along side 12th and 10th sedan we already have? It would be like old times when 10th pan car dominated on road racing. Just my thoughts thanks
