Thanks for all your help guys. I just ordered 8 sets of B3s and 3 sets of As. Now I'm just hoping the guy has them in stock or I'm SOL!!!

Is a lathe necessary to do well in GT2? Seems like it would be based on the amount of runs.

Also would it make much of a difference in GT2 between 4200 and 3800? I know with 19t 4200's are the only way to go, but I don't know with the 27t motors.

You are correct, the number of runs will determine whether your comm needs to be cut. One alternative is to use three comms and one can- one comm for practice, one for the first three Q's and the third for Q4 and the Main- along with new brushes every time you swap out the comm. Or you can use three motors & just set them up in advance. If you make the A, find someone to cut one of the comms- shouldn't be too difficult.

Also would it make much of a difference in GT2 between 4200 and 3800?
Depends on the amp draw and gearing of the motor you are using. 3800's should do just fine for most people, but if your motor is a butt-whuppin' amp sucker, then 4200's are the way to go. Typical 4200's have slightly higher voltage than 3800's, but not so much that they are absolutely necessary. If you're buying batteries then you will probably have to go with 4200's since 3800's seem very scarce.

Default EP4200 legal???

Hi guys I'm wondering if anyone knows if the East Power 4200 NiMh cells are legal for TCS competition? This is the what the rules say on the Tamiya TCS site:

The batteries that are allowed for the 2007 season are: Sanyo NI-CD 2400, Sanyo NI-MH HV 3000, 3300 & 3600, Panasonic 3000 Ultra Metal Hydride, Panasonic 3000 Stock Metal Hydride, GP (Gold Peak) 3300 & 3700, 4300 Intellect Batteries 3600, 3800, 4300 and LRP 3700, 4200 EPIC 3800. Basically, no NICD or NIMH battery cell is to exceed the 4300 mah barrier!

It's fairly vague because it says anything below 4300 is legal but it doesn't specifically mention the EP4200 cells. Any information would be much appreciated. Here is what the cells look like:

Thanks for the help rccardr! I will look into that option since buying a good lathe might be harder for the man on the budget....

Speaking of which, my bill to prepare for TCS in June is about $600. Does that seem high??? Man thought this was the low cost racing series lol.

Also, what do I need to do about transponders? Are they rented, provided, or what?

Wow. And you're a local, right? Which means that you dont have to pay for air fare, hotel, rental car, meals out, etc.- that's all PARTS?

I think my TCS bill for Aliso is like a hundred bucks for parts. Maybe that high. Not including air fare, yada, yada, yada. Unless you're Hara, one (OK, maybe two) sets of tires will do you just fine for the whole weekend. I'm running both GT3 and Mini and figure I'll burn up my kinda-still-OK B3's from Seattle and Memphis in practice, then mount up a new set of B3's for the Q's. If I make the A, I'll probably mount up another set unless my times are still good. For Mini, one set (and they are not exactly new) will last me the whole weekend. Already have batteries and motors (OY! have I got motors!), so the only thing I'll wear out is tires. And I'll probably pretty much destroy a body, but I've got a stack of them in the corner and since Aliso is the week after my beach vacation, there will be one or two newly painted ones available.

Well since i am running lipos for weekend play, I have to get more than some:
    It adds up fast sadly. I am getting a lot of different reads on tires. Some are saying up to 10 sets, some say as few as 3.

    Hey Doc,
    The Black Can Mabuchi Tuned Motor is actually 27 turns of 22 mil wire, with a softer brush compund than the Johnson Motor. GT2 Class I believe is 2 Black Motors per entrant max and this year a spec battery but it won't be GP3300's since Tamiya has no more stock. Fred will probably use GP3700 or maybe we can use IB3800 and IB4200.
    I learned a lot last year using the Black can Motor, those things are just like a Honda F1 motor (Gernade ready to explode)
    I am going to debut a new TB02R @ Fremont for GT3 Class and run my trusty TA05 for GT2.
    See ya, in Fremont!

    Are you sure about that? Seems to me we tore one of those down a couple years ago and it was a 23 turn with about 8 degrees of advance...

    They are 23 turn motors.
    When we went to worlds there was some confusion on what was the better motor. The out come was the black can was a 23 turn motor and it was faster, than the 25 turn GT tuned motor, that N1 was required to run.
    pretty much the explaination given to us all.

      You could just practice with old tires, then run a new set for qualifying and the mains. Someone would hook you up with cutting your comm. 2 packs will be OK for the race.

      Since I only run at the Tamiya track, i practice with lipos and Sorex tires because I am just having fun. For this I need some stuff to practice ahead of time too. I have a fairly new set of B3s I am going to use to practice for the next month. I will also look into seeing who will be around to cut the comm which would save a ton of money.
