FANS w/Heatsinks
#16
Is necessary fan battery, could not connect to main battery directly?

A good thing about wiring direct to the battery is that you can turn of the car and leave the fans running. This way when you get back from marshalling and pick your car up from scrutineering the motor has cooled down.

agreed, but that is direct soldering the battery to the speed control which is understandable.
I solder the fan wires to the speedo side of the battery plug which allows it to still be unplugged if need be but allows you to switch off the speedy and receiver but still have the battery plugged in and fans running. If you have the fan plugged into the receiver as soon as you switch off the fans are off as well.

i'm with james on fan/esc arrangement but i put in a 5v regulator in between to keep fan alive while i marshall/mess about Batt output is so high now that it can fry a 5v fan. Had that happened to a MM fan so i'm not taking chances.
Got a nice fan from farnell, epoxied it to 2 shortened 1.5mm el-cheapo allen keys that act as stand. Coupled all those to a ZPI magnesium heatsink...looks messy but they work.
Yokomo rebadge the zpi mg heatsink as yok SP-MPC

For fans its an edge to edge measurement. Motor fans are typically 30mm (except for the LRP one which is bigger). The LRP ESC uses a 25mm fan. The Novak brushless units I think use a 30mm fan.
I've just discovered the new, high output MuchMore fans - they move a lot of air. Anyone know what voltage they're rated for? I'm running my motor fans straight off the battery (which you have to in Australia) but I was wondering if that's too high for them?

I wire my fans with plugs so they can be easily disconnected if needed. I discovered the downside to the Sphere Comp TC Spec with it's permanently wired fan - it's difficult to hear the servo straining at the end of its travel when trying to set end points with the fan running, especially since its missing a blade. It will be good to be able to diconnect it when its not needed in those situations.
