in reply to Enkay, the shaft is 4mm dia, 63mm long overall. The pinion end of the shaft is 3.17mm dia, for 14.5mm. There's a circlip at 41.5mm. Front bearing is 10x4x3.5, rear bearings are 8x4x3.
What's my shoe size? 20c for best answer....
I decided to start building my Balckhawk500EP model next, and can't find any info on what motor/ESC combo to use. I have Motors from here to try, but most are for 450 models. They are mostly 3350KV to 3450KV like Typhoon 2215 & 2218. I ordered this one :H2223 2900KV. I thought I'd use the YEP 45Amp and 3s battery like Turnigy 2.2 and flightmax 2200 25c (or 30C) which I have. Suggestions?
Had a look at the Blackhawk specs and this should be a good motor to use,they recommend a 2800KV motor so this one at 2900KV will be fine,your other motors KV's are a bit high.
Thanks! I can't find the specs for this bird anywhere anymore, and I even have a printed (Color) manual that has little real info. I was originally thinking I would use a 15 tooth pinion with it. But manual shows 17t and 16t. I have stuck some TGY-2216MG servos in it(just starting), but am starting to think they are too nice for this (can use 'em in larger Ark500), and I can get away with something less.
I think this motor is aimed at 4s use, so on 3s, keep an eye on your ESC and battery temps. With the wrong setup, you could easily draw more than 50A. I'm using it on 4s on a 450 with a 12t pinion.
My 2223 2900kv is only pulling 33,000rpm unloaded at 16.0v - so it's behaving like a 2100kv motor. Anybody else experienced this?
My 2218 2500kv manages 43,000rpm * 16.5v, which translates to 2600kv. My Typhoon 2218 3450kv and 3500kv are right on the money at their claimed kv values.
I got this motor because my 2580kv scorpion 12 was a bit too slow and I noticed more head speed with the 2223 2900kv on the same settings but.... havent tested on a rpm sensor.
Mystery solved! I set my Superbrain ESC to 8 poles, since that's what's claimed for the Suppo version of this motor - but today I took off the can, and there are just 6 magnets! Waddayaknow!
This is a heavy motor, and it's really better suited to 4s use. On 3s, you'd just about be OK with a 13t pinion, but 14t or 15t would be better.
Depending on the setup, it can draw a lot of amps - the recommendation is for a 50A ESC. The dlux 55A looks good, but that's also heavy :(
I don't have this motor but I have the ESC Turnigy AE-45A and I am very happy with it. It support 2-6S and I used two different motors, both work really fine on that ESC. It lots of programming options and super smooth start. Note, this motor might be too slow for 3S helicopters.
Im sure there are shafts out there with the same specs. For the price, you might be better off getting a new motor. Did you burn up or break this shaft??
The main reason I wanted to try this motor and a similar 2600kv one was that it uses 4mm bearings and a 4mm shaft, stepped down to 3.17mm for the pinion. As such, the shaft is far more durable than the 3mm shafts on motors like the Typhoon 2215H and 2218H, which step up to 3.17mm for the pinion, and easily snap at that point.
Yes, you can. Well as in fast rc boats can be. I us motor 2218/1860kV in my rc hydrofoil with 3S 1300 mAh lipo/propp 2290.30 - 3 blade prop.. This one you can us with 2S,1000-1300 mAh Lipo, prop: 2299.30 graupner or 2 blade 35 mm..Must be used water cooled motor mount-in a confined space rc boats.
it is,sort of, but the shaft is 4mm turned down to 3.17 at the end. to use it with a reverse shaft you will need a collet on the bolt side to keep it in place or replace the shaft with a longer 4mm shaft. i use one of these for a prop drive with a 4mm SS shaft, made from rod i get at ****smallparts**** they sell precition centerless ground rod in 36" lenths for about $18.
Great little motor. Pulls just over 40 amps with 5X5 TGS speed prop on F-22 foamie using 3s 2200mah 25c battery w/60amp ESC. Approx 460watts on Turnigy Watt Meter. Haven't try a 4s battery yet but think it will need to go down slightly in prop size. Motor got hot but I was flying wot in 95-100 degree heat in the shade. Bought 2500, 2100 and 1860 KV motors also. 2100KV able to use 7X5 prop. Plan on trying 2500KV with 6X4 or 6X5 soon.

wires are too stiff but good in general. for a 450 is only for 4s setup, so not good for most 450's. On a 3s it will simpy be too slow. Tried this with a 40A tp esc and 20c 2200 turnigy and a 15 pinion, and everything got really hot on first battery with simple hover. At second battery esc stopped working (overheat protection) . Good motor , really powerfull, a lot of torgue , but hungry for amps

good motor for a 450 but with a 4s setup. be careful that it requires an esc larger than 50A.This motor is LARGE in size but works well over all .
