First Race! I need a pit caddy + heat sink

Hi Slot Forum,

I had my first 1/24 flat track race last week - I came in second to last. 😂 Speed and consistency will come, but I learned a lot and had fun! Anyways, I'm in need of a pit caddy and magnetic heat sink (all the guys were using them). Can someone help lend some advise on what to get? I found a couple pit caddies (see below), but I'm totally open to ideas/input. What I can't find anywhere are the aluminum magnetic heat sinks everyone was using between heats to cool down their motors.

JCR Caddy - I really like this one!

Thanks!

Hard to go wrong with any of the pit caddies that you have shown,......but, the JCR is my choice, and the choice of many.

As far as heat sinks, Check with PCH slot parts or MidAmerica.........JK and RGEO sinks are used by lots of folks.

Cheers

I know that in 1:32 it’s not a regular thing to see heat sinks, but if they were available, would there be any significance gaining in performance? I mean, many of the 1:32 motors have already vent holes or at least one face with a big opening .

When my club raced 1/32nd cars with powerful traction magnets the car's motors would get hot in a few laps and slow down. After we dumped the traction magnets that was no longer an issue. When I was racing commercial raceway 1/24th cars I would put those on a battery powered fan between heats. The fan had holders for braid cleaner and tire conditioner.

Thanks Chris! I found what I was looking for - below.

Unless you are using magnets (and more than one) it is highly (very highly) unlikely that any of the motors commonly used in 1/32 "plastic cars" will heat up to the point of needing any sort of external cooling.

As an aside, the vent holes in these plastic car motors actually do very little in terms of cooling,....many folks cover them up to prevent any junk on the track from entering the can, with no increase in motor temp, and many of the plastic car motors do not have any holes/vents at all.

The "vent" holes that are punched into the can, are not actually designed as vents, but rather the edge of the can that is punched inwards, acts as a stop to ensure that the magnets stay in place, and do not touch the armature.

So "cooling blocks" or fans are one less thing that the 1/32 racer needs to worry about/purchase..;)

Some 1/32nd motors have fairly large "vent" holes in the can that might contribute to better cooling. For sure large holes allow magnetic flux to get out of the can and increase a car's downforce if you race on plastic track. I have a no-contact IR thermometer, so I can measure the temperature of a motor case. I could take measurements of a motor with vents, the cover the vents and see how much the temperature goes up.

Don't think we are talking plastic chassis cars here, more like high performance wing cars with custom motors drawing lots of amps, a whole different world to use 'plastic' people.

Closing the loop here. I went with the JDR caddy. I have not used it in a race yet, but so far I like it!
