Most everyone in the stock class world who does anything remotely related to flywheel guns knows about this above motor, a popular flywheel upgrade, by some name or another:
- helicopter motors
- "180 motors"
- By the E-Flite/Blade part numbers:
- "The stock motors for the Blade CX2 and similar small coaxial RC helicopters"
- "RC motors"
What these motors are not, however, is proprietary to, or manufactured by or for, Blade/E-Flite. Rather, they are an off the shelf Mabuchi FK180SH-3240. That means going through Blade is not the only source. And certainly not the cheapest.
Blade simply fits them with pinions, suppression caps, an optional PTC, and a wire pigtail with connector and sells them at a markup as those familiar part numbers. I have known that since the first time I saw one, but I didn't think to search around until recently. Of course, we need none of that heli stuff, and in fact removing it is a bit of a chore especially for noobs - so next time you are looking for a set of "Blades", punch that Mabuchi model number into Google and see if any are up on eBay or the like.
I scored the above set of 3 (perfect for a full Rapidstrike swap) for $15.00 shipped.
Happy motor hunting!
A hint is that 12900RPM @ 3.0V also identifies a 3240 if the seller doesn't mention which wind their motors are. And stay away from the various other winds of these, the FF metal brush versions, and all the gazillions of FK130SH-xxxx listings. They are NOT what you want.
Voltage range: 11.1V and under (flywheel use)
Critical voltage (Nerf flywheel system): <7.2V
Stall current: ~40A per pair at 7.4V, ~65A per pair at 11.1V
Datasheet: Link (specs listed for 3.0V; even the stock helicopters are overvolting these more than 2 times that under a heavy load with good durability so no worries).
