HiMaxx motors anyone?

[hemna]

I've been browsing some sites online a bit, and it seems that the HiMaxx brushless motors look really good. The #'s on them look good and they are on the cheap (relatively). Has anyone used any of these in their planes? I have a House of Balsa P51D and an Astro 020 w/ Planetary Gearbox. I was thinking I might be able to return that, and replace it with the HiMaxx
HA2025-4243 ?

The specs on it are at

Max output is 175 watts vs. 200watts for the Astro 020, but at a fraction of the cost. The 020 cost me $250 (w/ ESC). I could save ~ $100 if I went w/ the HiMaxx and a Castle Creations 25amp ESC.

Any thoughts?

Read Steve Neu's Quiet Flyer motor review of the Chinese copy motor.

Basically, Steve said you get what you paid for.

that bad eh?

Well, it is not bad for the price. But are you expecting copy cat motor as good as the real one at 1/2 the price? The problem is those thing are not consistance as the good motors are. You might get lucky and get a better than average one, or not. From past experience, most of those products, Chinese, Czech.. are not as well made when they first appeared on the market, most of the products improve in later productions. The price offset to average sport modeler, they are good enough, as long as you are not pushing for 95% eff and 100% power all the time.

Like I mentioned somewhere before, not all brushless motor created equal. The eff ranges from 60%-94%. Just because they say brushless, does not imply quality. Also a nice thing about Astro, the repair facility is here in Ca. AstroBob is pretty good on repairs.

Buyer bewares.

good to keep in mind. I've been reading a big thread on the HiMaxx motors on rcgroups.com
at

http://www.rcgroups.com/forums/showthread.php?s=&threadid=163935&perpage=15&highlight=himaxx%20motor&pagenumber=1

and most folks seem to have good things to say about it. There have been a few guys that had problems with the planetary gearboxes going out to lunch on them. I'm only on page 12 of the thread and there seems to be a lot of traffic on it. I just wanted to see if someone local had tried this motor yet.

Greets:

Iv'e been flying an ultrfly furious bipe 3d with a Himax 2808-0850
and it really scoots! It has smokin power, and I had an incident where I was coming into a hard climb and it stalled and the motor cut off? I entered the field and did the "WALK OF SHAME" I observed that the stator and motor body had become undone! Yikes! well I sent it back to MPI and those dudes sent me a brand new motor! wow no hassle just in less than a week they sent me back a BRAND NEW ONE!! thats why I always try to by MPI. They have great customers service and the motors are powerful and BUILT!

Hope that helps!!!

the hymax motors are not as efficent as german hackers and lehners.

they take watts much over the ratings w/o demagging (due to inferior mags) better -so are capable of higher power settings. i don't own one but have seen the abuse they will tolerate (and the abuse a lehner/hacker won't tolerate) so if you don't care about purple and black cases they will fly your plane just fine! shafts may be brittle.

We're talking toy airplanes here right?

house of Balse Eh?...I'm currently (have been for about a year) working on a T-6 HOB conversion. I took a daring brushed outlook and tried simply for price, to put a brush 600 motor in it. It gets lots of tourque with the 2:1 gear ratio, and I think it should work pretty well, but your Himaxx Idea sounds easier. I was orrigionaly planning on simply mounting an outrunner to the front. An easy and effective solution. I would agree that the hacker motors are also very good, but I would not say no to a himax. A good buy. and good luck
