OMP Edge....Almost there!
 

Well I'm about to finish up my 40 size OMP Edge. Everything is finished and covered, I just need to glue on the wing, stab, and control surfaces and it should be ready to go! I was wondering what is best to glue the wing and stab on with? Epoxy or polyurethane glue? Here's a couple of pics, I'll post more before its first flight.

RE: OMP Edge....Almost there!
 

Either or those glues will work fine. If you use epoxy just clean off the excess with alchohol and paper towels before it dries. Urethane glue won't stick (very well) to the covering so it can be cleaned off even after it expands and cures. Also can be cleaned off with alcohol or acetone before curing.

Looks, good, mine is still in the box, no time to build at the moment[&o].

Good job dude. You will love this plane. I am about ready to maiden my second and I was depressed after the first one was destroyed.

Keep us informed and let us know how it flies.

RE: OMP Edge....Almost there!
 

What are you using for motivation and hardware?

At the business end I will be running a Irvine 46 with a 6oz. suillivan tank. JR 631 Tx with Hitec 425 servos on all the control surfaces. I'm also using all du-bro hardware, 4-40 rods with the plastic clevis's that have the metal pin, I think there called Quick Links? I should have it ready to go within this next week!

Far be it from me to disagree with THE Mike Pilkenton, but when I was about to glue the wing in my Edge, I asked here, and the consensus was, surprise!, medium CA. The problem, as Mike alludes to, is the mess that Epoxy makes. Since it doesn't seep in much, you have to put the glue in the opening before sliding the wing in, which smears it everywhere. I did it the easy way: Insert the wing, stuff any gaps with little bits of balsa, then put a line of medium CA around the joint between the wing and fuse.

RE: OMP Edge....Almost there!
 

I don't know if the CA would eat the foam in the fuse or not? I also have a pretty tight fit on the wing to fuse joint. I'm not sure when I slide the wing in place if the epoxy/polyurethane glue will get in there. Also I still have not cut out were my engine will go. Did you guys counter sink your engine onto the hardwood rails or just leave it on the outside? Thanks!

RE: OMP Edge....Almost there!
 

Well Mike in DC that may work for the all wood versions of years ago and we all certainly use CA on the wood models as that's the easiest to do but personally I would not use regular CA on teh foam core versions of the model. I guess it would work ok but you would only be gluing to the outer balsa skin. Now maybe using the foam safe CAs would be the ultimate trick to do! Hadn't thought about that before now.

RE: OMP Edge....Almost there!
 

Ooops! Sorry, forgot about the new fuse material!

RE: OMP Edge....Almost there!
 

Hello!
I am finishing a 40 size OMP Edge and I was asking me the some questions, and I think I will do so:
First I fit the wing in position in the fuse, and then I will use a syringe filled up with 30' epoxi (I will have all te time to work slowly) with attached a thin small beak that can be easily inserted for 1/16" between the wing and the fuse.
At this point I will spry a little amount of glue every 1/2" both sides.
After that I will move the wing a little and so the glue take the right position.
And last I will create a little cord of glue in the 90° corner all around both sides

What do you think about what I said?

Excuse my bad english: I am italian.....

RE: OMP Edge....Almost there!
 

Now I think that is a great compromise. The only thing I would do different would be to cover the airplane first. I juat find it easier to deal with smaller pieces than to cover a whole airframe.

So to recap what you do is pull the wing out a little bit put on some glue then do the same to the other side, wiggle it around a bit and let it set?

If I got that right or not I will be trying that on the YAK.

RE: OMP Edge....Almost there!
 

I will glue the wing after covered the plane too.
The job can be done in 2 or 3 times:
First begin down side gluing epoxi with the syringe every inch or less; important near the leading edge.
Then let it dry and repeat upper side.
Then wiggle it around in the down side a bit and let it set.
In the upperside we can make a smaller cord using thick CA

RE: OMP Edge....Almost there!
 

Using a syringe is a great idea and many have done this technique. Wish I had some nice thin syringe tips! If the foam safe CA wasn't so dang expensive maybe that would be a great technique as well. personally I've still been using the urethane glues with no problem.

RE: OMP Edge....Almost there!
 

I finished mine!! I will fly it sunday....:D

Sweeeett!, good looking plane.

RE: OMP Edge....Almost there!
 

Nice Westy! Let us know how it goes!

Shovel-Head: Is it done yet?

RE: OMP Edge....Almost there!
 

Yes sir Westy, good looking slab! We want to see flying pics after this weekend!

RE: OMP Edge....Almost there!
 

I'm putting the landing gear on mine right this second! I painted them yesterday and had to let them dry over night. I think I am going to add some white letters on my wing to break up some of the blue. I'll post some more pics of mine soon!

RE: OMP Edge....Almost there!
 

MMMhhhh....
I am a little afraid..........

Anyway, can you tell me if are allright these settings:

2 Flight mode conditions:

First with about 20°/25° all around (a little more on rudder) and an expo of -30%
Second at the max: about 45° all around and an expo of -50%

On a swich there is a Land condition with -25% flaps and +7% elev

RE: OMP Edge....Almost there!
 

Well I'm having a little trouble getting mine to balance correctly! It's seems very tail heavy at 1.75 to 2 inches behind the spar, thats even with my engine and battary has far forward as possible. Thats also without the tank,prop, or spinner attached but I don't see how they will make that big of a diffrence. I'm also debating to counter sink my engine or not, and comments on which might be better? Here's a few more pics of mine by the way!

RE: OMP Edge....Almost there!
 

It will make a difference for sure.

RE: OMP Edge....Almost there!
 

Westy, sounds good on the throws and expo. I also use more expo when I go to high rates. Skip the landing mode setup though, you don't need it and it's only going to mess you up if you accidently hit that switch.

Shovel-head, You definately need to balance with everything installed plus don't judge the balance until you fly it. The big wide profile wing allows for a cg much further bach than you are probably used to. Still to the recommendation per the instructions and you will be fine.

RE: OMP Edge....Almost there!
 

Very good!!! The test fly survived!! But not without little problems:
1) to have exact the CG at 1.85" aft main spar I had to advance the battery near the engine and put a little plomb on the nose. In that way it flies horizontal also inverted.
2) I had some trouble (some engine cut offs) with carburation the OS 46 AX. Solved with fuel 20% oil and only 5% nitro.
3) With the APC 12.25X3.75 I am afraid to go at max power because I hear the engine going too high with a prop so thin.....
4) When I feel the engine perfect: then I could fly well: It flies very beautiful!! But I need to learn a lot before doing some manouvers near the ground like hovering ecc ecc......
Anyway thankyou very much!!! At the field everyone is interested at my new Edge!!!!!

RE: OMP Edge....Almost there!
 

Westy, the 12.25x3.75 prop is very thin but also very heavy... I run a 46 AX on a pylon plane with a 8.8 x 8.75 and spin it at 16.5K and it has survived well so far. Don't sweat the full throttle any.
