USA warehouse now open. Our USA warehouse is now open! Low cost shipping and an ever growing variety make ordering from the US warehouse even better value!
You have to tell us what you are going to use it for, it is hard to give you advise if we dont no this... It is not easy to compare a 98grams motor (S2445-3890) to this 180 g one.
OK, it is many years since I raced rc cars, and I dont have experience of brushless systems on them, but I would strongly suggest that you go for this, cause it has almost dubble mass. It can surely take a beating better then the S2445, which is a 1/16 car motor.
I'm sure it's not...HK is notorious for under-specing their motors. I'm going to try to abuse one here next month...gotta couple of em slow shipped to me.
I dont think so, there is no cogging when spining it. It has 2 magnetic poles. Kv came out to bee 3500 meassured with K1 Kv meter at 11,6 volts. Io was 2,5A.

Hi.
Tested with EDF Ducted Fan Unit 5Blade 2.68inch 68mm intake lip mounted. After 15 mins balancing fan (almost to perfect balancing) I tested it with a 4S 2200 45C B Grade Lipo at full power with this results:
Max current 62 Amp.
Max power 940Watts.
After 5 mins running at full power motor at only 55ºC.
Great motor for power but be carefully, my bearings need been lubricated because the front one sound like a box of rocks before that.
Motor handles very well current and seems capable of more.
I only substract 1 star for bearing problem. Seems well made, and robust. Good deal anyway, a new EDF motor with impressive results, with this combination nothing to envy to Lander setups, except sound.
Pekný motor pre môj offshore o rozmere 60cm, a 2S lipol baterie. uvidí sa aký vikon bude mat, magnety sú extremne silne na nom.

I am running this motor in the High Power 4bl fan, 70mm, on 4S without any problem:
Zippy Compact 4S 3300 35C: 54A / 14,95V / 807W = 1.400 g thrust with intake lip.
Motor stays cool even without any heatsink. I mounted this combo in my Habu and it performs much better than the original E-Flite fan. Very short take-offs and unlimited verticals are now possible. Great motor and great value!
