I sent the e-mail to OMP but I gues Mike is to bussy to answer it now. So maybe I can get the answer here - you read this formu 10 times a day, right

Here is my crazy idea. Looking around for planes I found OMP site with 80inch Edge 540. So here is what got me.

I have H9 Edge 540 (old 27%) 78inch span. The plane powered by Brison 2.4 flies very heavy as it has only 1000 sq inch. The other thing is, that I hate this one piece HUGE WING. I was going to replace this wing with something scratch built but still to many projects piled up on my desk. I asked WH if their wing from 84inch Edge would fit, but they can sell only as ARF and it just cost to much.

OMP Edge is available as a kit so maybe this is the way to go. This big wing (I can shorten it maybe by one rib to keep my Edge 78 inches wingspan) may actually fit my H9 Edge. I will need to modify the fuse to supoport two piece wing through a wing tube tho.

So here are my questions:

1. Can I buy just a wing kit from 80inch OMP Edge 540 (with plans to built it on)?
2. What would be the cost shipped to California (including wing tube and ailerons)?
3. How much this wing weights (the original H9 wing is 3lb)?

If this thing works I may actually also try to shorten it by another rib to fit it in Powerline Hobbies Edge 72 inch span. This little plane has only 800 sq inch wing area and would benefit from at least 1000+ sq inch. Powerline Hobbies dumped the plane (it's called discontinued) so no help from them.

I know it may be crazy, but what the heck - it's always worth to ask.

Yes

$75 - $10 shipping

3. How much this wing weights (the original H9 wing is 3lb)?
I don't my plane handy but prolly 1.5 lb or less.

Do you have pics of your plane so we can take a look of what we are dealing with?

That's sounds much better than WH foam wing. How can I contact you?

This is old (discontinued model) H9 Edge 540 78inch wing span. It has one piece wing with ugly cut-in in the fuselage (makes the fuselage very weak here). I'm going to add side walls to the fuselage here and the mount the tube. The only question here is if the wing chord at the root in OMP Edge is to bei to fit between the cowl and the tail

. What is the root and tip chord?

Pictures - hmm, let me see. This is not my plane, but the same H9 Edge, just to give you an idea - the ugly fuselage cut for the one piece wing:

and here how it looks from the top:

The other one (Powerline Hobbies) looks much better as it already has a wing tube design. The wing is very nice (very good aerodynamic) but the plane would do better 3D with the lower wingloading. Now it is over 30oz/sq in (it flies much batter than it looks like tho) and getting it down to 26 oz/sq in (wing 1000 inch) or even better to 24oz/sq (1100 inch wing) would be a great deal. For that wing I wouldn't need a tube as PLH already has one.

But the first priority is the H9 Edge. I like this plane a lot (I have a worm spt in my heart for it), but now I have to force myself to fly it. Not much fun.

I think I have enough building skills even to modify OMP wing to fit it in my planes.

Im not sure of the inside root rib right now ... Mike will let you know tomorrow.

Also I see you mentioned that that wing was over 1000 Sq In and would benefit on the Edge. The OMP 80" wing is 1600 Sq In so I can already tell that's it's at least going to look pretty .... different. Even with taking out a rib section it will still prolly be over 1200 maybe 1300.

I'd like to watch you do this for sure! You can call me direct tomorrow to order number on website, use New York number. But you might want to wait for Mike to respond to this thread first. I'll make sure he looks at it tomorrow and gives you the numbers.

Looking at the picture I estimate: 23.5 inch chord at root, 16.5 inch chord at tip - am I right? This including ailerons.

If I'm right about the chord numbers, after removing 4 inches from the span at the root (to compensate for the fuselage width and the wingspan 78 inch) new root chord will be about 21inches. So total wing area will be about 1450 sq inches. I'm very fine with that

I'l call tomorrow morning (I mean California morning). For saving from misspelling I'll PM you addresses. Thanks a lot.

Your also going to have to change the angle of the ribs to accomodate a tapered fuse a few degrees.

OMP 80" Edge wing root is 24.8" including aileron. Tip is 15.25". Thickness at root is 4". I did see your email to me and was sure I responded????? Anyway, sounds like an interesting project. I always thought the H9 Edge was extremly heavy on the wing loading as well You need to be around 20 or less in my opinion. Maybe 21-22 for experienced pilots but any more than that and the planes get squirrly on low speeds. My honest opinion is to not use the OMP 80" wing for this plane unless you want to turn it into more of less a funfly style plane. Keep in mind the OMp wing is very thick, tons of surface area, and has flat built up ailerons. All great for the funfly designs but the H9 Edge is designed more for IMAC style flying. This requires a much different set of design parameters for the wing. Yes you could take the basic OMP Edge wing and modify heavily to work but it might be easier to just start from scratch. Either way I will be glad to help you along the way.

Thank you for the numbers. I was close

. The same estimation gives me chord without ailerons 19.5" root and 13" tip. However the TE will be modified for airfoiled ailerons so I think my wing will be about 21 by 14.5.

Sorry, I didn't get it. But don't worry. I'm really happy with OMP service, support and communication. I've been looking for any help with my H9 Edge for months and now I'm blaming myself, that I didn't get to OMP sooner.

It was my first IMAC plane then, but now I know a little more. Now I don't want to buy any more planes made by H9. I now understend better why my plane is 'discontinued'.

Right now with wingloading around 32 it flies heavy. It does IMAC acrobatics but I can't push the envelope even a bit because it will snap in nasty way. This is the plane that tought me do big round loops (no square corners possible

) and land fast.

I could make a wing from scratch but converting OMP has many advantages:

1. Proven design. Fat big OMP wing flies 3D. I mean crazy 3D. This airfoil will make my H9 much more forgiven for stalling. OMP size wing (modified in TE part) will be perfect for H9 to get wingloading about 24oz/sq ft. It still will not be '3D crazy' like OMP Edge but at least will fly high alpha without nasty surprises.

2. Strong and light. I was not sure if I can design light wing that will be strong enough. OMP already did it. No brainer here.

3. Learning. I have built many planes but all of them were small scale (2 - 6 lb). Now I have big scale 100" span Wilga (tug plane) 15-20lb on my building board. I'm done with the fuselage, but the wing is still in front of me. Building OMP wing I will teach me to build big, light and strong wing. This experience I wil use cutting Wilga's wing. I don't trust plans, so I wanted to see first how 'big boys ' do it.

Thanks again, I will report the reslults on RCU in my thread Instruction for Hangar 9 Edge 540 (1.20)

Dion,

Did you ship the wing kit? I don't see any charges on my CC yet. Are the any problems? Let me know

Uh, I know I was gone all last week but I think there was some miscommunication. I'll have to personally pack this order as the parts I'll have to dig out myself from old stock. I'll check with Dion or John to make sure they have your order correct.

Thanks Mike,

I called Dion Friday, but was to late for the day. Dion got all my info. I will confirm thet today. Just in case of any miscommunication, I wanted the wing kit (I mean all the wood parts and plans to built them on), the wing tube with sleves (the pieces that go inside the wing) PLUS additional piece of sleve (about 10 inches) that I will use inside my H9 Edge fuselage.

I'm very anxious to make this wing, as I tested new smoke system on H9 Edge (perry pump and remote valve) and it works great. So to carry additional pound of smoke fluid I need that wing.

RysiuM, the kit went out last week so be looking for it. Keep us informed on this project as it sounds like a very interesting modification.
