I have an Orion Experience brushless ESC and motor on my B4 buggy. It's a great setup for me and the system works very well.

So, here's the situation; the specifications indicate the ESC is capable of putting out more amps if it has a cooling fan attached. However, it doesn't specify if the fan has to be powered by the ESC's fan connector or if it can run off the receiver or directly from the battery. Plus, how does the ESC put out more power when a fan is attached? Is there an internal trigger in the fan circuit that signals it to put out more juice or does simply running cooler allow it to increase the power output?

Additionally, Orion uses some type of micro plug on the ESC where the fan is to be attached. I've never seen this type of plug anywhere. The 25mm fan I found has a more conventional red mini plug like those used for small battery packs. The fan plug on the ESC has very tiny wires, perhaps 30 gauge or something, while the fan has slightly larger wire, probably more like 22 gauge. Does anyone know where I can find a connector or pigtail that will fit the Orion ESC plug so I can hook the fan into it? I thought about cutting the Orion connector and replacing it with the matching connector for the fan, but the wires are so damn small and I don't think there's enough slack to work that close to the ESC.

I'm sure others out there have run into fan compatability problems with other brands of ESC's. I figured Orion / KO Propo is a popular enough brand that they would use more conventional connectors. How do I cool my ESC?

I may have to post photos later this evening; I'm in the office right now... Don't tell the boss!

Thanks to all for your advice.
