I am Ready for an Outrunner but I Need Help

I have been doing the GWS/Himaxx gearbox thing for a long time now, you know...bent shafts and noisey and I have been wanting to try an OR but I need some advise. I am flying outdoor only as there's no indoor flying here and the planes I have been flying are flat foamy 3D'ers in the 11-13 oz. range. The EPS I am using is a Himaxx 2015/5400 on a GWS 350-DX with a 12/6 SF prop on 2s 1320 TP's and 2s 1500 Kokams but I have a bunch of 3s in the same mah. I like the way the 2s flies the planes on the 12/6 because I spend most of the flights hovering, torque rolling and learning the other 3D stuff at present so I want an OR that will give me the same oerformance as the EPS mentioned above. I am open to any and all info and money is not really a major concern because I have plenty of econo foamys also.
The plane I am building now is a Vertigo Pro with a 38" W.S. and should be 13-15 oz.AUW. Any help would sure come in hndy as I am sort of in the dark about Out Runners...the AXI 2212/26 or 34 has been the motors that keeps poping up as one of the better alternatives but I am still well open to any other motors at this time.

All I can say is if you're bending shafts on other motors, you're likely to knock the magnets out of an outrunner..

The shafts are very soft and can bend from just a soft landing, it's not from straight in at WOT...and I doubt I will knock the magnets out of the motor on landing that otherwise bend the GWS shafts..thanks.

Any other suggestions..?

Boss,

Check out the motor chart at Park Flyer Motors:

http://www.parkflyermotors.com/secur...om.asp?recid=7

Specs for the 2212/26 and /34 are included on 2S and 3S cells.

I think you'll find that the 34 is going to be your best bet on 3S. The 26 wind is a little hot (current draw wise) for your 3S cells and not hot enough for 2S.

I fly the /26 and love it but current draws from a 3S are in the 15A range WOT with an 11x4.7...

Cheers,
Griz

The 2212/34 is ideal for 3s - here are some numbers which might be useful in influencing your decision!:

For 3 cell lipo packs I would get the 34 turn. for 2 cell packs get the 20 turn. I have the 26 and it is great but on 3 cells you need to keep the prop down to 9-10"

For more sport flying the 26 turn is the motor IMHO. Of course you can still do 3d with the 26 turn but if that is all you are into, go for the 34 turn.

Highflier

PS. 3/4 throttle with 10" prop on the 26 turn will hover my 15 oz 3DX. Only problem is the thumbs.... can only hold hover for a short time.

Not a problem. I guess what I am saying is that for 3d flying the 26 will work fine. BUt I bet the 34 is more effeicent since it will swing the larger prop.

The AXI is truely an amazing motor. I have a hacker b20 15l geared that I hate compared to the AXI.

Highflyer...what do you think about running the 2212/34 on 2s with say a 12/6 GWS or an 11/7 APC SF..? I am real close to going with the 2212/34 but I am really wanting to stay with 2s if I can to keep the weight down. I ahve also been looking at the Rotex 26/5/15 on 2s and a 12/6 maybe.
I am not trying to be pickey...I just am trying to get similar performance to the Himax setup or something like that but maybe not with all the vertical but a good aggressive climbout. I want an out runner but I just want to get the right one without having to buy 3 or 4 to get there...maybe I am asking to much, but I should be able to make a good determination from what info I get here.

Boss,
Sorry I do not have experience with 2s packs. All mine are 3s I figured I would start with one or another and not mix it up. However if you are going to be 100% 2s cells I would not get the /34 I would consider the /26 which will give you the option to go 3s but I might just go with the /20 which will perform better on the lower voltage. of course the /26 proped up would probably work well.

So you really like the Axi over the Hacker that much..? I will probably order a 2212 of some wind tomorrow...I was thinking of calling Northeast Sailplane...they seem to have a better price that Hobby Lobby does...have you ever dealt with them..?

Yep, never a problem with any of the internet vendors. And I have the hacker working ok now. But not anywhere to what I had hoped. I look at it this way.
The AXI is giving my 3dx 20 minutes of flight. A hacker should be more effecient. Well I am willing to change a pack every 20 minutes. THe axi is quiter and has no gear box. Makes it a little lighter. Maybe I would have a slightly difference opinon if I had deeper gearing or if I had a 18L instead of the 15L

You will not regret the AXI. Best motor performace for the price. IMHO

I flew my 3dx in 15 MPH winds today. Without a brushless it would be pieces. But every time the wind did something really bad I just waited till I got the nose up Punch the throttle and next thing you know I had 3 mistakes of altitiude under my plane.
