Can't say much for longevity as its only had 3 batteries through it, but I'm using this on my HK450FBL with a 15T pinion and 4s.
Seems good so far. The 2218H 3450kv I had before was way overkill, even with a 11T pinion.
Looks and runs very well I'm using it on a scratch built 30mm water jet design. Ran at 27 Amps on a 3C very cool running. Didn't have a thrust rig setup but its way more than an NQD 20 mm delivers, and at lower RPM
Good value nice motorI have this in my Mini Protos running on both 3s and 4s using a CC ICE 50. For 3s I run 2400 RPM for nice smooth flying. On 4s I'm running 2900 RPM and it's pretty much a rocket. According to the data logger in the ICE my peaks are just under 800W at 52A (I need to dial down the collective pitch a pinch). It comes down hot after flying on 4s, mainly because with the 16T pinion I'm having to run at too low of a throttle. On 3s it comes down warm to the touch.
I'm using 8KHz pulse modulation with normal timing. On low timing it has a habit of spinning up in the reverse direction. Doesn't hurt anything on a heli, luckily, but it took me a while to figure out what was wrong.I need to retract my previous review where I said it came with an open winding...it didnt! I poked around it to see what was wrong and somehow I managed to install a no-continuity bullet connector. How I managed to do this I have no clue...but I guess sticking a wire into a pool of solder can get messed up sometimes, hmmmm????
Anyway, my motor runs. Measured no-load KV is at 2115, no load current at 2.11A at 11.08 volt. This is an 8 pole motor.Well, it's a motor. Couldnt tell how good it is because it doesnt work, 2 known good esc's couldnt get it started, seems like one of the phases is open. Of course HK says they want it back before considering warranty on a brand new motor just purchased and never used...and shipping costs make this a foolhardy proposition. It might be simpler just to order another motor from HK and hope that it will work? Or just get a quality brand motor like possibly Scorpion and have it actually work on arrival. Thanks Hobbyking!i thought that i might give one a go
i run it on 4s on a 13 pinion in my scale 450gt
it runs well and will not get hot, headspeed about 2400
smooth and cheap powerReally great motor for new miniprotos-450 on 4S. 15teeth pinion is the max that can be used. This combination gives outstanding 3500rpm headspeed. Real tasmanian devil , call it "TAZ". 1600mAh per 5minutes of brutal 3D flying. Motor is little only about 40celsius. Not warm/hot like scorpion ones.
Good efficiency.Great engine! hobbyking if only to realize it would be perfect for EDF 2250kv 70mm, because they get to 1350g. a real boost.Rcvd it today after more than 20 days of ordering. Ordered from Hong Kong and it TAAKKKEESSS a long time to get it. HK will need to come up with better shipping strategy.Questo un gran motore:
1) costa poco
2) su edf 70mm 5 pale f 24A a 6s e 1,2kg di spinta.
3) resiste a voltaggi alti.
5) ben bilanciato
Assicuratevi di usare un mozzo per albero motore affidabile con grani da serraggio se lo usate su una edf.
This is a great engine:
2) to edf 70mm 5 blade 24A to 6s ago and 1.2 kg of thrust.
3) resistant to high voltages.
4) is light
5) is well balanced
Be sure to use a hub hex to shaft by tightening screws with reliable if you use it on a edf.
