I was the first person who got picked on for the motor test and the number comes out barely under 14,000 rpm or whatever the limit is.

hmmm... so it's not the motor... so tell us where you cheat?

whatever promotes the continued success of TCS and brings us more racers or even keep existing ones F103... BL, Lipo, etc.

am i the only one excited about 10.5/lipo with a lowered weight limit in GT1?

Minis, silver cans, spec lipos, and strict RPM limits (please stick to your guns this year, Fred!).

I might just have to start looking for airfare!

I'm bummed about the Porsche class. Not so much that you aren't running it, but that you already announced it's a dead class. Now it won't bring squat on eBay!

F103GT will NOT be offered as a second class. The only second class is 1/10th Off Road.

This weekend's Glen Burnie, Maryland TCS driver count is (drum roll, please!): 92! (that's 92 entries, not 92 drivers).

OK, not as many as Laurel used to bring in, but my guess is that the guys from LI and Boston are going over to Connecticut on August 10th instead of driving all the way down to DC- price O' gas and all that.

Here's the breakdown:
GT1-12
GT2-15
GT3-16
Mini-34 (THE BIGGEST CLASS, but sadly, not the 101 that Ed and Robbie dreamed of)
Spec-5
F103-7
Vintage-3 (come on guys, this is a FREEBIE CLASS, yank those old TA01, TA02 or FF01 cars out of the closet and come race with us!)

I also understand that there will NOT be a Tamiya rep at this event due to other obligations, so I've volunteered to assist with tech questions as they arise. Which means that in addition to Webb hanging around our EZ-Up tent city glomming Mini secrets, he will also be asking incessant questions about the legality of stuff like anodized wheel nuts on Spec class cars. Who says this ain't fun?

Thanks Andrew. Now, how about the motor details?

Are you working on the torque arm with Fred?

For mini silver can rules here is what I think my prediction is 13,500 rpm @ 5 volts that gives enough leeway for the motor to be broke in without surpassing the RPM limit thats of course utilizing the brush and bearing technique. Also its not high enough where people cant get there by just simply asking around. I think 12,500 is to low and 14,000 is to high so Fred I would suggest 13,000 -13,500 and if you fail you fail. Also the rules should state that you can tune to that number how ever you see fit thats of course not opening the can or cranking of the comm but anything like that would throw the motor far beyond those type of rpm limits anyway so let it rip set the limit and let em at it any way they want. Except opening the can of course.

as long as the race management is not allowing improvement of mag strength... (seem to recall some 11.5k GT3 motors that were pulling very tall gears at regionals)

torque arm +1

They were using a Muchmore style motor tester at the Aliso Regional.

My guess is that the reason the RPM limits have not yet been established is because TA has not yet received their shipment of spec motors. There are several different batches out there right now and each type winds up at a slightly different RPM- some as low as 12,500, others as high as 13,750- using the same simple break in techniques.

I dunno about the "however you get there" school of motor management. My guess is that Fred's Perfect TCS Nationals would not include magnetic enhancement of any kind (easy to tech for with a simple torque arm) to go along with the RPM limits. If he wants us to just arrive-and-drive, that works for me. Y'all are going to woop my butt anyway.

Except for Brandon, because he'll punch me in the nuts, break his hand, and have to sit out this year's event. On the other hand, he'll be getting all the lap dances...
