Heads up: Watch the video on the Soaring USA website. IF you want that kind of performance, that was a geared Neu on 4S.

Not sure on prop and watts, but I am sure it's around 1000w.

Ok, still no nearer to finding the "perfect" setup for my needs. The geared setups I have seen on this thread are generally based around the NEU motors which are hard to find here in Europe and also the Hacker/Kontronik etc outfits are expensive and as I am not into competition stuff I would rather keep it light(ish) and simple. So far I have come up with the following motors which may do the job :

Turnigy/ or similar 3542/5
Turnigy/or similar 3548/5
Hyperion GS3014-10
Hyperion GS3020-8
MVVS Redline

I do have some ARC motors from my EDF projects

and not sure if they would be any good in this application

any ideas??

The ARC's won't swing a big enough prop. They are totally out of the question.

I would go with the Redliner. That's what I am going to outfit my Orion with this Spring.

Should be perfect on 3S or 4S. Mine will run a 4S 2200mah.

The Hyperions are an option. You need to get the motor wires past the motor though.

Would love to hear some solutions to budget gb set ups if possible. Would have thought that arc 2858-1 might be an option, although suits 6s? which may not suit the orion, size wise. Is there a gb to go onto it? Kontronic KPH25/27? i don't know ? Shaft size ? Flanges etc? Another gb?
Cheaper interchangable innrunner gb solutions? Perhaps there is a thread dedicatied to this question?
Hope I am not waisting anybodys time with this query? Thanks for listerning. brendan

Edit, unfortunatly 4mm shaft on the arc and the kontronic gb accept 3.17mm shaft.

Cheep motor for this plane would be a Hyperion GS 2218-10 with a 12x6 or 11x8 prop, tp 1300 3s battery CC 50 controller ,don't run the bursts to long on hot days it will overheat.
Also ,set up elevator so it moves almost to the end of the slot in the fin,this plane loves elevator.
This plane is really sweet, love it.

MVVS Redline?

I'm just curious... how does one stick a MVVS Redline motor, diameter 38mm, weight 9.5 oz in the Orion which has an OUTSIDE nose diameter of 38mm? And... at 9.5 oz will make that bird hopelessly nose heavy.

Just curious...

You'll notice the row of ????? after my quote as this motor was suggested to me by another which made me also curious. The motor will in fact install, you need to put something like a 3mm spacer on the front to get it to fit (lighter versions have been installed in the Orion)as it has an INSIDE diameter of 36mm, but you are right about the weight, way to much. I was under the impression that it had been done by others.

Actually I have done a bit of work on ecalc and the turnigy/dualsky or whatever (they all come out the same factory) 3542/5 is a good bet as it is able to push near 2kilo of thrust if propped right which is more than enough and the 3548/5 will do near 2.5kilos on 4cells at at the expense of extra weight so I will try the lighter option first and can always buy the larger motor if I am not happy as they are cheap enough.

MVVS Redline?

Yep, noticed the ???????? That goes for the 30 series Hyperions as well but require the power wires to skate by the motor to boot... big problem.

I was looking more at johnnyrocco123's rather absolute statement wherein he was using this motor... with a 4S 2200mAh battery. Now we're talking some serious weight! That will make this fine bird hard to balance as it really comes alive when the CG is 104 to 108 mm aft of the wing LE.

Your edit...

Sorry yakhakker,

I missed your edit. Yep, the 3542/5 could be very interesting at only 4.7 oz to boot.
When propped correctly it should suck up 45A just fine.

Keep us posted...

Rofly, My original question was to try to determine what non gearbox (a personal choice) setups Orion owners were using, if any,whether it be in or out runners and what sort of performance they they were getting from them and other info such as prop sizes etc.The best blast for buck if you like but it seems most are opting for geared units, at least thats how I am seeing it. I am not into competition so I am not looking for out and out performance, and like many these days, I am on a tighter budget than I would like but at the same time would like to find a Ferrari for the price of a Focus,don't we all, but it seems I am near alone in this task. By the way I was referring to the GS range from Hyperion and as they are specially made for narrow nose gliders I see no reason why they will not fit. I will keep anyone who is interested in the loop.

My friends setup is in an Enigma. I have talked to a builder who confirmed fitting it into an Orion.

The weight is obviously an issue. I still plan to give the MVVS a try in mine.

I just have the luxury of trying it before buying one.

I won't get around to it til later in the Spring, but I will definitely come back here and post.

NOTE: If I can find a good deal on a geared Neu Motor, I will go that route.

+1 on the neu geared set up, for efficiency alone. Have on order since oct '12 a 1112/1y 6.7 for a 2m sailplane at 1800g. It is killing me seeing the summer slip by and my plane stuck in the cupboard. Was promised before christmas! anyway! Hopefully giving 180 oz of thrust on 4s. Too much for the orion? Weight at 6.5 oz 185g
1110/1y 6.7 at 5.8oz 165g might be sweet for the orion on 3s.
What is the lightest weight up front?

Looking back I see a 1105/2y with 4.4 maxon at 4.1oz 116g
You couldn't go much lighter could you?

Building mine with a geared Neu 1105/2Y with the Maxxon 4.4:1 gearbox. Looks like I can get it to balance with a 3S 2200 mah or if I get lucky maybe an 1800. The weight ready to go should be in the 50-52 oz area. Just don't see how you could go any lighter motor/battery combined and still get her to balance.

if you look at page 11 post 411 my scorpion 2221/10 with GB @ 28mm will awing large prop @ only 4.6oz will give 600+watts 55-60 amp and only cost me under $90. bought the motor for $49 used near new and Gb for 38.
