I wouldn't recommend any ESC under 25A. Even 25A is a little low. These motors pull a lot of current. I haven't had a problem using these motors with 30A Turnigy Plush ESC but I have fried a 25A ESC with them. Ive used these motors on planes, quadcopters, hexacopters, and tricopters. They are great motors!
Yes, The ones included are normally called Prop Spinners and are designed for a standard 3mm shaft. You can also buy Prop Savers which use an elastic to hold the prop on, so in case of a crash it un-hooks and the prop doesn't instantly shatter. In the case of a quad, depending on how heavy it is, I'd recommend the Spinners.
Alright just got 6 for my h550 hexcopter and guess what? One of those screws wedged itself inside the triangular propellor head holder. So 1 of my 6 motors and prop holders cant work because the screw! And this was straight out of the box. So is there anything HK can do?
Hi i am building a quadcopter and i estimate the total weight to be about 1.2 kg. I want a quad to fly fast and do acrobatics. Will these motors have enough thrust? How many grams of thrust does each one give? if this is not the right motor what would be a good motor for under $20? Thanks
I put it on a little Combat plane the other day just to see how it would do.The plane weight is 12.5 oz so it screams. I am running a 3s 2200mah battery with the 8x6 prop. It goes vertical so easy it's not even funny. Everybody wants to know what I have in that little plane.This motor works great in everything I have put it in.I had it in a yak 54 and it did good there too. I need to buy more just to have around. It's very universal.
The shaft is 2.96 mm and the diameter of the prop driver is 6.2 mm. Have to drill 6.2 holes in my 5 mm props but do not yet have the right tools. I did not see info about these sizes mentioned in here. I expected 3.17 mm for the shaft and hoped for a 5 mm prop driver. (or 6 since tools for that are readily available).
Sure, I use them with 9x4.7 SF props on the turnigy talon v2. It is my first quad so I can't compare it with other motors but in this setup the quad hovers around mid-throttle. I will post a short video at the talon v2 page.
there are lots of motors here that'll give better numbers than posted..this, however, isn't one of them. 'tried this motor on 4s with a twin motor plane that has limited prop size. They burned up after a short run. Yes, we proped it down too.
should have lots of power as motors are rated at 700gr thrust each. You may want to down size props tho as 9x47 may heat up motors. check temp after built and if hot u can try 8x38 (props are cheap)I just put 2 of these in CL-415 water bomber with 3 blade 8x4 props 1200gr AUW Tons of power
Only female must be soldered to your ESC. Male is soldered to the motors!

I bought two of this motor for use in my Canadair (Bombardier) 415 from HK. I'm using two Turnigy Plush 25 A ESCs, powered by 3s LiPo. In test-running them using separate receivers and batteries, I am amazed that their kv ratings are within single-digits of each other (their pitch is synchronized). Of course, I drowned them in Corrosion-X to waterproof them (this is a float plane, after all!) They seem to have excellent pulling power using the supplied 8x3.8 props, although I have not run them through my testing yet. Now if we just get some decent flying weather here!
Great value. Two of these small motors pull my cl-415 canadair easily out of the water.

Great little motor. I bought one for my funder and lighting scratchbuilt (see rcgroups) and it powers this plane just nicely. I'm using an APC 8x6 prop.
Shaft is very hard and you won't cut it with a hacksaw. You'll need a grinder. I trimmed mine so that the adaptor collet fits neat against the bell.
And the supplied prop adapter is very good quality. Much better than the ones you buy here. They all tend to cause vibrations but not this one.
