I've been using this on my 6s 450 with 360mm blades for months. It gets just warm after 6 minutes of sport flying. Its rated for 500 watts maximum so its ok as long as you stay well below that rating.
Is ther a replacement shaft for this motor? I have two of this motors and one of this shaft has an accident. I can't found anywhere this shaft, he is 3.7 and 4mm diameter. Thanks
Harald the Shaft diameter: 3.17mm there should be plenty in the motor parts area. Also inside old computer CDROMS are guide shafts. They make great replacement shafts. And they are free.
hello, in this topic, how do you unscrew the grubscrub that holds the shaft? do i have to use a debonder or something like that? i've twisted the shaft but i can't loosen it. thanks
well, finally i've found a replacement shaft, it will not leave it as original, but it works and has the flat part and the securing mark on the right position. i will correct Kellyann, on the shaft dimensions because inside the motor, it is 4mm and only the expossed part is 3.17, so if you get a 3.17 it will not work. the shaft is www.link is all 4mm, but it fits perfectly (i replaced it last night). regards.-
*jzzto if you could find a pinion drilled for 4mm, you could use a plain 4mm shaft - but maybe you could repost your link Nato style e.g. **** Lima India November Kilo etc. for the shaft you found.
Will it be ok if I use a 70 amp esc in a 4s lipo setup. Another option is to go with the 60 amp esc but the hk redbrick does not offer one with a bec. I'd rather a 70 amp but please let me know because I dont want to take a risk
There would be no problems with the 4S. I have one of this with a turingy 60A with BEC (TURNIGY Plush 60amp Speed Controller)and have no problems on 3S. As far as I know, the motor will draw the amps, if it has extra amps they would not represent a significant problem if the range is not too big.
Thak you joe45, but I was looking for a more technical solution, lets say generical to learn more about the relations between ESC and motors (I'm a rookie on this issues)
Bought this motor for my Goldberg Endurance sailplane, but I don't know if it is defective or not. I used a Turnigy Sentry ESC and a 2200mAh 3S battery, but the motor will not turn! It just starts to tremble (small erratic movements in both directions) and won't start. I tried to swap the connections with no results. I know the ESC is OK cause it works just fine with a AXI3212/34 motor. So, do you guys believe I'm doing something wrong or is it possible that the motor is really defective? Thanks...
I had same motor working fine for some time and when i removed it from mi funjet it started doing same thing as you describe. If it can be damaged by just removing from plane i believe it could easely arrive dead
Anybody got one of these H22xx series? The specs seem to suit my needs... but I need a 4mm shaft, custom one anyway. So, what size are the bearings, any possibility to replace them to make a 4mm shaft fit?
Thanks!
This is in the right kv range for 6S setup and around 13-15T pinion from what I've researched on the web. People are getting 3S 1300mah packs and running them in series with motors of this kv range and enjoying power throughout the flight opposed to just the first 3 minutes on a 3S setup.
The specs say 15V (4s) max :( We need a cost efficient 6s HK alternative for 450 helis. Is there a chanse the specs are won? Where is the logic in using a 1860kv motor on 4s?
"And what makes a motor a 3S motor or a 6S...?"
RPM is what dictates how many volts a motor can handle, the bearings would only be rated to a certain speed. But I doubt this motor has different bearings to the 3200kv H2218, which would be spinning faster on 4S than this motor on 6S... So I cant see why not, besides its only a $10 motor.
so, what about miniprotos with 4S, it seems to be the right motor

ok here is my real review, my mdm1 fox is now 850g with the H2218, 3s1300(30C) and a graupner 7,5x4 folding prop. in stationary climb(almost vertical) i get the following numbers: 10,8V 23A 248W rmps from 15400 dropping to 14800
after 65s runtime in 220s flighttime the motor is only slightly warm(no cooling!). will take a bigger prop now, 8x5 will give unlimited vertical so i'm impressed by performance and quality for that little money

bought this motor for my parkmaster, excellent climbout power at 1/2 throttle, 10 min. flytime on 2200 mah, plush 60 amp esc. plenty of power for all 3d moves. excellent motor
Nicely build. Run it on 3S and 4S off load. No problem. Sounds perfect. It did'nt come with bullet connectors, male or female. Came with 4 screws, washers and spring washers. No X type mounting plate was included. So don't forget to order these parts with the motor. Quality is very good. Thanks HK
