Micro Outrunner Motor 4500KV made for 3.7 volt operation.
We did some in shop testing on this motor with a 7.4V pack, GWS 2.5-.8 prop-.98 amps, 31,900RPM, 103F, pitch speed about 18mph. GWS 2.5-1 prop, 1.1 amps, 30,800 RPM, 105F, pitch speed about 22mph. Both of these props were run for 1 minute. We also tested with the GWS 3-2 props, the motor overheated quickly and was down about 12k RPM. DO NOT try to run a 3" prop on 2S here. Current and tach readings taking at start, temp reading at end. The motor seems stable to me with 2.5" prop 2S setups. Certainly in air loads would be lower. I am getting excited to design a Sub-Micro-Stick! Notice although the RPM seems way too high for indoor, the pitch speed is very modest. You should note that our testing indicates an amp limit similar to the manufacturers below. When we obtain the new single cell ESC, we'll do some similar testing to determine some useful setups for 1 Lipo.

Micro Outrunner Motor 4500KV for 7.4 volt operation. Use up to ~3-4oz models. Specifications: KV 4500 Voltage 7.4V No load current 0.5A No load RPM 33200 +/- 3% Max continuous current 2A Continuous RPM 21000+/- 3% Resistance 1.18ohm Dimensions 13 x 4.6mm Shaft Dia. 1.5mm Weight 3.5g
Primarily intended for 2S and 3S running on 5" and smaller props. Perfect motor to upgrade you Blade CX or add to a Multiplex Fox. Great for small models.
I am unable to get sensible data from motor calculators for this motor using available data. Actual test results below in chart. Note, we used 2 and 3S Lipo's of various sizes. The voltage listed is "as depressed" under the conditions of the test. Props used are GWS. If you can provide a link to serious motor constants please email me. I'm not interested in other dealers websites where the same incorrect data from the MFG's website are repeated. These guys are LAZY and never check out anything for themselves. On occasion we do. ;-)
