[NSRCA-discussion] E-Question HXT motors

Emory,
What ESC and battery did you use with that. Is the Jeti spin 99 still the right choice for that motor?

Thanks for the info.

Hey Anthony,

>From my experience, I was amazed at how well the HXT motor performed. I don't remember the stats exactly, but they were very close to the performance I was seeing with the AXI. I believe it was slightly less efficient (maybe 2 more amps drawn) and had about 200 less RPM than the AXI. Like someone mentioned, I kept waiting for it to fail, but it didn't. I had well over 100 flights on it when I decided to plant the airplane in the ground. Based on my experience with it, I wouldn't hesitate to try one again in the future. I mostly used the APC 20x15 prop.

Hi Mike,
Are you sure on that prop size?

Ok, some in depth answers.

We did in fact test this motor last season on a Black Magic V2, flying masters. We used the HXT 63-64B 230kv motor. We used a CC HV85 controller, Tanic and vampower packs.

Power is certainly not a problem for this motor. It is fairly comparable to the AXI. 2700 watts, 82 amps, 6200 RPM on an APC 20x14. the motor never got over 110 degrees.

Longevity: we got well over 100 flights on it before the plane was lost, no problems whatsoever. This was using Esprit stand off mounts as well, o nose mounting.

No can issues, nothing, it just delivered. your results may vary of course. These are "cheap" chinese motors and you do not have the support structure in place like the name brands. but considering you can buy almost 4 of them for the price of one AXI, it's pretty interesting.

I've run a lot of these chinese motors and maybe I'm just lucky, but I just don't have problems. I keep hearing about problems with darned near everything, including name brand stuff, and the only issue we've run into yet was a very early bearing failure with an AXI...that's all. Ever.

I have yet to install one of these on a VF3, and wonder about it because by it's very nature you will have to use more power to fly it. I realize 82 amps is a lot, but the packs never got warm, nor did the speed control or motor, so who knows.

in short, if this is your first forray into electrics of this size, you would probably be better off with the AXI just from the standpoint of support. But so far I can't find a thing wrong with this motor, or else I am just that lucky (and THAT is highly unlikely, trust me!)

As I am doing my research into the world of electric pattern I have come across the HXT line of electric motors. It appears that the HXT 63-64 B230 is a fraction of the cost of the comparable AXI motor ($60 vs.$200+) with very similar performance numbers, physical dimensions, etc. In fact, according to the info I saw it is even 12 grams lighter.

Being a realist I have to ask the question; what's the catch? Will it burn out after three flights, does it run excessively hot, does it smell like bacon? I don't get it. Is it just a cheap Chinese knock off, a very good value, or both? What I really want to know is, is the motor viable for F3A pattern?

I appreciate any information you guys can provide, particularly from those who have used them or seen them run.

Thanks a bunch
Anthony
