Well according to the rules "No modifications or optional parts allowed on motor can, endbell, stator, or rotor." Is the aluminum heat sink considered an optional part? Seems the rules are a bit vague regarding the heat sink. I would like to know the official rule on this because I'm looking to buy a cooling fan soon.

Is this really an issue. No fans that replace the ring has been a rule for a long time. Clips, clamps, chassis mounts, etc... All should be allowed. If you are wanting a no fan rule cause you can't fit one on your motor, you are not looking hard enough.

I'd agree with #2. I see this more of a maintenance item than a performance booster. I don't change my gearing because I'm running a cooler.... I'm just hoping it makes my motor last longer and therefore makes racing cheaper for me. I'm running this one... http://www.integy.com/st_prod.html?p...8#.ULzaBu8xZ_Y

#2 here as well.

To misquote "You'll have to pry my heatsink from my cold motor ..."
A good heatsink is much more effective and cheaper than a fan. #1 will just make fans more vulnerable and prone to breakage, especially for those with less than perfect driving skills.
So, #2 would be my first choice and #3 is better than #1.

Apparently I'm missing something here as in not digging deep enough into the gray areas of the rulebook. How hot are you folks getting these motors that a fan is really needed?
Weekend before last I ran several back to back practices (200+ laps) overnight at Minnreg of 40-45 laps each with 40 on the timing, 3.84 ratio, car was overweight and the driver was certainly not as smooth on the throttle as you guys likely are. First run came off at 128 and the rest were in the mid 130 range.

Yes, but some people's car get hot climbing up this mole hill!
Ditto on the heat, I don't think my car has seen much over 115*F. We do run a pretty high FDR though.

2 .. 1 ... no wait 17 !!
My fan is mounted 3/8" behind the motor with servo tape on the chassis, works just fine.

Personally I hate fans and for the setups that everyone is running (motor timing only) there should be no reason minus improper gearing or significant problems with you car. I ran a Xray T1 for over a year with the front belt rubbing a groove in the lipo case and even then it came off around 160-165.
I can see the TC/1-12 guys NEEDING a fan on the motor and/or esc but on VTA? I'd put it right up there with ceramic bearings.

The reason the LRP unit was quickly "banned" if I remember correctly, was to follow ROAR's decision to limit fan size to 30x30 and a miximum of (2) fans. The esc fan counting as (1). Both the Novak and LRP ae also "rigidly mounted" to the motor. Which some could argue, is acting like a full time "peltier"(sp) (yes, I know, there is no "powered" heat source)
