This Motor does good work in 4S.

However, Motor becomes the high heat in 5S very much.

The power of Motor weakens very much.

The buyer must understand it.

The power that Motor is splendid in the case of 4S.

However, 5S and the use of 6S are impossible.

Motor is high heat.

The motor performs well, but be sure to tighten the front of the bearing housing. It is threaded on NOT pressed and mine loosened when I gave it full throttle in my 3" Hoye fan. I had to disassemble the unit to repair it. For this I give it 4 stars.

I am running this in a HET Mini Fan on 5 cells and it works great. I will add the test results when I get them.

It is a heavy, quality motor, therefor can be run at higher power leval in practice. I tested it in a 3 inch (80 mm) ducted fan unit. With a 4 cell battery, it only drew 21 Amps. Requires at least a 5 cell lipo, unless used in a bigger fan unit. One reservation is the poor soldering of connectors. They came off after few unplugging. Recommend resoldering before use. Very smooth in operation.
