Next was the rudder, as you can see, it is flat, stick built. To give some perspective on the size of this bird I compared it to the rudder on my H9 1/3 Sukhoi.
So far, the trickiest part of the build was getting the turtledeck and the canopy straight with the fuse. I failed. It is really hard to determine weather everything is straight until it is glued and sanded. Anyhow, mine didn't turn out as well as I had hoped. Hopefully it doesnt affect the flight characteristics.

AFSalmon and Dion. If you are following this thread. The parts bag comes with 2 1/2" x 1/2" wooden dowels used as hard points for the control horns. The parts list also lists 2. Actually there should be 3. 1 for the rudder and 2 for the elevators. Maybe you could contact the manufacturer and make them aware of this mistake. No biggie as I will be hitting the hobby shop tomorrow for other supplies.
I also assembled the horiz stab and trial fit it to the fuse. It was a perfect fit. . The rudder was sanded and hinged.
Over the weekend I will assemble the elev, hinge them and take a pic of the completed tail section. After that, it's on to the wings. I was hoping to drag this project out till march or april of next year in hopes of seing the 55xtreme. At the rate that this is going together I will be done very soon.

We are watching Crash. Thanks for all the feedback. You should just buy yourself a used 50 cc to slap on it until that 55 is released. You know how some releases work in this hobby, you may not see that motor for 2 years. I certainly don't want to wait that long to see it fly!

LOL. No way Dion. The temps are dropping here and this bird won't be done for another few weeks. I will give BME till March to produce. If not, it's DA city.

Thanks Crash for the feedback. Yes I caught that 1/2" dowel mistake during the first kit run also. You are right: three are needed for the tail! I'll have to think of a way to help builders assure easier assembly of the top sections.

A ZDZ 60 should be a very good combo for this plane. I've seen several ZDZ 60's run and they appear to be very strong engines. When I designed the plane, that was my top end criteria for engine choices anyway.

Here's the latest picture of my Hybrid finally with a smoke system.

Thanks guys. I think that what happened to the turtledeck is this. Some of the 1/4" balsa sticks were a very soft balsa and some of it was a harder balsa (normal). When I pulled the top of the turtledeck together to install the 1/8 x 1" cap one side "bowed" while the other side stayed somewhat straight. I think that a simple fix for this would be to add a former about 1/2 way up the turtledeck to assure that both sides "bend" in uniform. The pic below is exaggerated.

on-your-six

does this plane use a pull pull on the rudder & 2 elevator servos
or one servo for each mounted on the rear sides of the fuse.
cant get a hold of omp to ask questions
thanks for any info

Pull Pull on rudder then 2 elev servos mounted on the tail.

OH. Before I forget. I stand corrected. Although the material list only stated (2) 1/2 x 1/2" doewls there were 3 of them in the bag. Good catch OMP. I have the horiz stab finished. Last night I framed up one elev and I will be finishing the second one tonight. I will post pics later tonight. The final step in assembly will be the wings. Wings always make me nervous. When the wings begin my posts will become a little more detailed.

Well. With the exception of some sanding that needs to be done, the fuse and tailfeathers are complete. Everything turned out good.
I unrolled the plans for the wings and got a bit confused. Both wings are printed on the same sheet. One is printed with solid lines and the other is printed over top of the other with dotted lines. My question is this.

Looking at the plans, it appears that BOTH wing halves are built upside down. Is that correct?

I will post pictures later tonight.

AFSalmon

Yes, both wings are built upside down. This is common on a "flat-top" wing such as anEdge 540. The wing panels taper upward from the root to the tip and the wing is flat from tip to tip on the top. So building each wing panel upside allows you to assemble with all the ribs 90 degrees to the building board.

Thanks Mike.
Well, wing construction begins tonight. The fuse is complete and ready for covering. I will cut out the pull pull exits first.

Crash90

My Feedback: (17)

OK. Wing construction has begun. I will try to post a step by step.
Step 1. Pic 1 Glue balsa rib 1A to Ply rib 1. This is done on both root ribs. Be sure to make a left and a right side.
Step 2 pic 2. Find the rib jig and the aileron jig and glue some scrap pieces to pin through.
Step 3 pic 3. Glue the wing tube supports to the back of ribs 2,3 and 4. Again being sure to make a right side and a left side. Don't forget that the wing is built upside down. Do this for both wing halves.
Step 4 pic 4. The far left rib shows small 1/4" ply blocks glued to the root rib 1 . This is where I will drill and tap for the nylon wing bolts.

So far so good. Waiting for glue to dry, more to come.

Lookin good Crash. I'm watching this thread too.

I saw Mike fly his pretty bird at Nashville last weekend and it was wicked cool to see a "profile" with smoke!

Hey Mike, what's your setup on your edge? I think you said a DA, but i forgot the servos and smoke equipment.

The wings are going together quickly.

Can anybody reply on putting a ZDZ 80 in this bird ? I have one laying around and would like to install in this plane.

AFSalmon

Ok, let me see if I can clarify:

The jigs are to be placed under the ribs at the rear edge before the step for the subspars. It looks like from your picture you have R1 sitting on the step. Move the jig inward some so the rib is sitting higher. It also looks like your aileron jig is not sitting flat on the board. Make sure your building board is flat and doesn't bow down. The wing trailing edge jig is the most important one so make sure this is placed correctly. Here are some pictures from the manual that show the correct location.

Yes the two wing bolt holes are on the rib center and the thrust line as well. The wing tube hole is not. I think this is what you are getting confused with. The wing tube hole is not on the center line (see fuselage drawing on plans) because this is a "flat-top" wing. So the wing tube runs parallel to the tops of the ribs but as the ribs get thicker towards the root, obviously the wing tube will be offset to the high side. So don't go by that opening but use the illustration on the plans as your guide.

Quicksand, I answered your question on the other thread about the ZDZ 80. It's really based on if the engine will fit or not. We're using the DA 50 here and I've got the header/canister setup on mine. The Nashville ProBro meet was the first time I ran the smoke system and wow was that cool. Actually too much smoke as it started to bog the engine down from reingestion. Gotta do some tweaking on it. Servos are 945s on the elevators, two each 645s on each wing panel, 805 on the rudder.

Uh, might help if I actually attach the pictures! Forgot to mention the aileron trailing edge jig was added after the first prototype pictures were made so the manaul doesn't show the actual aileron jig. But it's placed the same way the wing jig is.

Crash90

My Feedback: (17)

Thanks. I edited my post because I figured out the problem last night. Yeah, when I placed R1 on the jig properly, everything else fell into place perfectly. Thanks again.

Just keeping an eye on the thread. thinking about buying one for this winter's project and putting a da 50 in her.

Are you installing a smoke system in this plane your building?

I'm gonna ask a dumb question... How do you get the motor into it?

Looking good Crash....

If you look at the pic on the OMP website you can see that the front of the fuse is "open". In the pictures there doesnt appear to be much room to get the engine in and out. I was originally going to convert to a removeable cowl. Now that the fuse is built I can see that there is PLENTY of room to work.

The size of this thing is surprising, the fuse is as tall as if not taller than my 1/3 Sukhoi.

You insert the motor from the bottom.
