Awesome lightweight little inrunner motor. This paired with a 70mm FMS 8b rotor on a 4s 2500mah 50C lipo puts out 65A settled and over 1.6 kgs thrust. Sound is nice and whooshy too if you have it balanced. The weight of the whole combo is 190g. Not bad at all.

I have a doctor mad motor for my 70 mm fan, It runs great I order 2 of these to use on a A320 plan I just finished. Can't wait to try them.

Hello !

Just tried this motor on a RC speed boat ! That's a very good motor for the price. As good as Leopard motors and better than 2poles motors. More powerfull because of the 4poles. And good surprise with the bearings which look very good ! The only little problem is that shaft is 4mm and not 3.17mm as said on the product's page !

Hello again,

I thought I gave it 5 crowns but it became just 4. No reason not to give this motor 5 crowns over all. Big bucks for the money!!! Good work HK.

Hello,

I have just resently got my 3300 kV from HK and I have made some initial tests. All the dimensions exept the diameter is right, the diameter is 29,4 mm. I have modyfied a 69 mm Wemo fan house to take the motor, no problems at all. I just bought a Dremel sanding drum (nr 502) that is about 29 mm, it will expand a little when it is rotating. Very easy to get the housing exact 29,4 mm. My initial tests on the work-bench gave the following figures. 4 cells, 16,5 V gave 39 Amps and 604 Watts. 5 cells, 20,34 V gave 51,8 Amps and 962 Watts and a huge thrust from the Wemo, no significant temperature issues, but I am going to use a heatsink on the motor if I go for a 5 cell-setup. It was no problem to get a perfect balance in the fan/motor setup. I will now modify a Tomahawk Viper to take this setup and see what it will give. I will come back with the thrust figures shortly. I bought the motor alone from HK and it came out well under 200 grams, freight cost just 5 dollars to Sweden. It seems to be a fine motor to a very low price.
