Default Cooling Device...
I really don't think the rules are very clear on the usage of a cooling device... Looking for someone to clarify if this is typically an issue at other tracks?

I have read the rules many times...

No modifications or optional parts allowed on motor can
If it's not in the rules, and does not encompass the spirit of slower, controlled racing with realistic looking cars, consider it illegal.
Sounds pretty cut and dry to me, no parts allowed on motor can. A heat sink is an optional part, putting it on the motor makes it illegal. It's not specifically mentioned in the rules, so it's illegal.

No big deal either way for me... Lap times were the same start to finish with or without. I know others were asked to remove them locally and was just curious where the general VTA community stood on the topic.

Default rsd springs reflex racing
Do anyone know anything about these springs. I brought a spring set from my lhs to use on xray t2 09. They didn't have a set of xray springs only sold them in pairs. I know they are aftermarket springs for the t6.1

Is it legal or non-legal in VTA to run motor fan or heatsink with built in fan?

Thanks

The original intent was to dis-allow the "optional" permanent heat sink/fan made by Novak which required the motor to be physically taken apart to install it. The use of any other optional heatsink fan has always been legal, with the exception of the LRP model that had a 40mm fan.

It was also implemented to dis-allow the light weight, vented, optional internal fan assembly made by Eagle racing and sold thru Integy.

I am pretty sure that a fan alone is not illegal. A clip on heatsink I think is ok, but I do remember there being a problem with the replacement Novak center ring that has the heatsink on it. That I believe was not allowed.

Default Thanks for the information
I kinda figured that would be the case as the intent was for the motor to not be modified with optional performance parts.

Thanks

I interpret the rule as no heat sinks to discourage people from over gearing and having to replace motors constantly due to heat damage. Some people are intent on winning and dont mind dumping money on new motors, so they gear to the moon and have a faster car. To me, this is not "the spirit of the class".

Heat sink or not those guys will still over gear, so I guess it doesnt matter.

It is a basic fact that gearing is direclty related to how well your car is working and getting through the corners. An effecent chassis can pull more gear than a non-effecent chassis. Some may burn up motors not because they are over-geared but because they are over-geared for their setup.

I push my motor hard but have been running the same motor for well over a month now with no decrease in performance and it temps out at 160ish after 8 min run.

You have to ask yourself are you really getting beat down the straights or through the infield... Be honest on this quesiton... It matters!

Regarding the heat sinks and fans... I can take them or leave them, laptimes were unchanged either way.

I would like to USVTA allow us to use non Novak motors . Is Novak afraid that they can't compete with other motor manufacturers ?

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.

RSD makes a nice fan mount that bolts to the chassis.
