Looks like these motors along with all the SK series are to be discontinued and be replace with the SK3 series, however, so far, I'm not impressed with what i've seen from other members who purchased the new ones series. I.e. from initial inspection and performance, motor windings are thinner, magnets are fewer, but more importantly, the bearings, are not japanese, but inferior chinese. And they don't seem to have the equivilent torque compared to the old SK series from what other members have said. I won't be getting rid of my old Sk series motors in hurry. Incidentialy, you can still find the old Sk series if you do a search for their makers, emp and type in, eg, 5065.

Grandioser Motor! Harmoniert wunderbar mit dem TURNIGY Sentilon100A HV 5-12S BESC (Ver4).

Habe ihn in meiner Extreme Flight Extra mit 1.8m Spannweite eingesetzt. Damit erreiche ich Spitzenstrme von ca. 68A mit einer Engel 18x11 Kohle Luftschraube.

Damit ist alles mglich inkl. Torquen, auch wegsteigen aus dem Torquen ist kein Problem.

Mit einer 20x10 APC war die Leistung noch einmal deutlich hher. Damit hat der Motor ca. 80A gezogen.

Angetrieben wird der Motor von 8S (2x4S) Zippy Flightmax 5000 mAh mit 25C.

Die Lager des Motors sind nicht die besten, die man kaufen kann. Ich habe mir bei Conrad (ja, ist ne Apotheke, aber der einzigste Hndler, der alle lieferbar hatte) Kermaik Hybridlager gekauft. Ich habe schon Beitrge gelsen, dass das den Stromverbrauch um ca. 10 senken soll bei gleicher Ausgansleistung.

Die Kermaik Hybridlager sind bereits bei mir angekommen, allerdings bin ich noch nicht dazugekommen sie zu verbauen.

Die Leistung von 2100 Watt ist (auch mit den originalen Lagern) absolut plausibel.

Type your review here.

Try to include as much data asThis engine is of poor quality: the first flight unscrewing the plate and blocking later: magnet off.

Got my motor today !!!

Well its not what i expected... The shaft of the motor inst fixed solid and the entire can of the motor just sits to one side and rests on the magnets. removed the grub screws , tried to reposition it.... no good.

If you turn the motor the magnets just slide and grind on each.

so i have a totally unusable product, that will cost me more to send it back than its worth.

HK wont replace it unless it goes back to HK...... so in effect i loose $$$ if i ship it back or i keep it as a useless motor / paper weight.

Thanks HK for ripping me off and talking my money !

Flying about 12 lbs an Aeroworks .90 - 1.20 electric conversion with a 100a ESC swinging a 19x10 thin electric. We've been flying this for 1 year and the motor has been flawless so far. We just upgraded from 4s2p 3800 MAH to 4s2p 5000 mah batts and removed 200g of lead from the nose.

Just got my shipment in today. After a brief inspection it was apparent most of the complaints were true. I spun the motor by hand and felt clicking. I had already decided to replace the original bearings with ceramics anyway. After careful disassembly I found the windings are fair but loose, so I put a drop of med CA on the far end to keep them in place. The large bearing is from Singapore but the dual bearings were unmarked but higher grade. The rotor seems unbalanced due to uneven spacing and epoxy quantities. Will have to correct that while I wait on the Ceramic bearings.
More later.
