It seems that they are better known for the boat guys. http://www.youtube.com/results?searc...be.r0XkrgxVgt4

I bought myself a 2940/2200kv as a 5s motor for my Jolt before I go for something expensive. Just did some initial test and first impression is pretty good.

It weights 183g (182g listed). IR was measured to be 16.2/16.4/16.3mOhms (16mOhms listed) between each two of the three wires. The good thing is the no load current is lower than the crappy motors with cheap laminates. I got 1.25A with 3s and 1.5A with 5s. Both packs are fully charged. The results is comparable to a Neu 1115/2D, which is of similar kv. I will post more when I finish building my plane.

That's good to hear! I already have my legs for my Jolt, but I might have to pick one of these up when the Rifle 1m comes out

You can easily measure the IR with a constant current source and a voltage meter. You can use your Lipo charger for the CC source. Just put the motor in series of an empty battery and set a charging current. Then read the voltage drop across the motor wires using the mV range. Make sure the testers in the voltage meter contact the motor wires directly to eliminate the contact resistance. Then you can get the IR by dividing the voltage drop by the charging current. The accuracy of the test depends on the accuracy of the voltage meter and the CC source. I usually series a current meter with the motor for the accurate reading of the current when using a charger as a CC source.

The TP motor fits in my Jolt.
