Would like to know which would give me the best performance. Thanks

I just gave the HC2808-0860 a try on an E-Flight Tribute today. What a huge disappointment. I’m hoping that maybe I had my speed control setup incorrectly because this motor couldn’t perform even close to the E-Flight 370 and a 6.6:1 gearing that I replaced it with. Aside from maybe a timing setting in the speed control I can’t figure why this motor performed so poorly. Here is what I’m using:

Very poor performance with this setup:
E-Flight Tribute 15 oz.
HC2808-0860
APC 10X4.7
Castle Creations Phoenix 25
Thunder Power 1320 - 3S1P
GWS Receiver
HS 55’s X4

VERY Good performance with this setup (Same exact components except motor and prop):
E-Flight Tribute 15 oz.
E-Flight 370 w/Himaxx 6.6:1 Gear
APC 11X4.7
Castle Creations Phoenix 25
Thunder Power 1320 - 3S1P
GWS Receiver
HS 55’s X4

I hope I missed something in setup as this motor is going back tomorrow otherwise. I’m disappointed as I really liked the idea of not having to use a gear box and I also liked the easy mounting to the GWS style wood block.

They're pretty attractive for the price. I picked up a Himax 2812-0650 at radicalrc. . . now looking for a bird to put it in.

A 2808 is really not a good choice for a 15 oz plane from what I have read. You will have to either lose weoght or go to the 2812 series to turn a larger prop. Could loose a ounce just on the battery pack alone, an 830 to 860 pack capable of 10 amps would be more fitting.

Killer

I was actually going to the Hobby store to pick up the AXI 2212-34 and they didn't have them in stock. So the sales guy suggest the Himaxx 2808 and explained it should perform similar to the E-Flight 370 but with the benefits of the outrunner motor and $55.00. I was very pleased and excited until I tried it on my plane.

So what Himaxx outrunner motor will perform as well as the 370 in a 6.6:1 GB? Will the 2812 do the trick for a 16 oz. Foamy 3D style?

The 2208 0980 worked great on a T3D II using a 10X4.7 and a 2 cell 1200. With a 3S 700 it was a rocket. This is an 8 oz plane though. I should have the results of a 2812-0850 in the next day or so. It is on a FF 36" Extra 300 and I am expecting good results, but I will post here and let you know.

What do you mean by well. A Himax 2015 is around a 100 watt motor and with gearing properly able to spin a larger prop more effectively. The Outrunner that you have is spinning a smaller prop but producing about the same amount of watts. If you want the watts to produce more thrust you need to A increase the rpms of the prop or B get a different motor that can turn a larger prop with out exceeding the current max.
When the guy at the LHS said the 2808 had the same power as an Axi 2212-34 or the E370 geared he was right, but what he did not tell you is that the Axi and the E370 has the ability to turn a much larger prop to generate more thrust to fly a heavier plane.

2808 will NOT work on a 15 oz plane if you want any performance. I have been testing these motors to know the best ones to carry for my planes as an outrunner option. The 2812 -650 work and swings a 13x6.5 at 10.5 amps with ok vertical but the 2812-850 with a 12x6 does even better (closer to a can with gearbox) pulling 14 amps at full throttle. But you can't pull that 14 amps long, about 15 secs. More than this is bad on the motor and most packs so you must have throttle control. Not bad motors for the price Jason www.InsaneFoamies.com

I have the HC2808-0860 w/ APC 9/3.8 SF prop/tech 3s 1200mah/AUW. 120z
3D foamy Model.

it fly pretty good have enough power to pull out if need it.

I’m not familiar with outrunners yet; however, I expect performance to be similar to what I’m getting with the E-Flight 370 w/6.6:1 but, in the outrunner configuration.

I like to fly 3D with a Foamy Factory 36” 300s @14.5 oz. (I use a E-Flight 370 w/6.6:1, 11X4.7 APC, 1320 TP LiPo 3s1P on this plane currently and would like to use an outrunner), and a Foamy Factory 40” 300s @17.5 oz.(I use an E-Flight 400 w/5.33:1, 12X6 APC, 1320 TP LiPo 3s1P on this plane currently and maybe I’ll use an outrunner later if a suitable choice exist)

Try a 2812-0850 GWS 10x4.7

The 2808 is not a comparison for the 2212 Axi. The 2812 is a closer match. I would not say that a 2808 was the match of an Eflight Park 370/Himax 2015, the 2812 possibly.

Over in Power Systems someone did some compariaon testing between the Axi 2212 and Himax 2812 (I don't remember the Kvs but they were close, like 850 and 860). With smaller props they were just about equal. But with larger props the Axi truned a bit faster and had more thrust. I don't remember the amps/watts to do so though.
