Default Super Lazy Ace

I am beginning to start a scratch build of a Super Lazy Ace. Old Chuck Cunningham design. I ordered all of my balsa today from Lonestar balsa. This makes me quite happy that they are up and running again, and wanted to give them my business.
I am looking really hard at installing an MT 70cc twin gas engine for power. I have also decided to change the airfoil to a clark Y as I prefer the more curved section on the bottom of the Leading edge from the stock airfoil. It is also a little thicker section than stock. I know this airfoil will perform better for my application. (this topic has already been thoroughly hashed out in the aerodynamics section).
some of the other changes I am going to make are slide on wings utilizing wing tubes. I want to leave the center section of the top wing attached to the cabane struts to ease field assembly. Also, I am going to turn this into a WW1 2 seater type aircraft. I think this airplane begs to be dressed up into something with a little more character. I will be going after something German with a tail gunner and such.
For covering, I will be using the light weight ceconite or similar full scale fabric to keep the costs down and improve the quality over the film or hobby marketed fabrics.
I am not sure if i will do a full build thread but will post some occasional updates on my progress. once I get all of my parts ready, I want to move rapidly as I would like to have this flying by the end of the summer.

Great project! I love Chuck's designs. Built his Druine Turbulent and still have it. I will be watching your progress.

Have fun!

Yes, I have not heard anything bad about his aircraft. This will be my first. It should be a fun build.

I have just ordered my fabric now as well. I am also motivated to keep this build inexpensive, so i am using a dacron fabric from Aircraft spruce. A 60" x 36" sheet is $3.25. So I ordered 10 yards. I can apply this with Balsarite or dope. Then seal it up with Poly-U or more dope. It is heat shrinkable as well and is actually designed for full scale gliders. I am actually looking forward to using this covering. I will have to get something built first!
I will probably start with the Stabalizer and go from there. It will build quickly. I am mostly making templates for the ribs and such right now. I will get some pics up when I have something interesting to show. My goal is to have this one flying by September.

You'll love that full scale covering. I just finished covering and painting a giant scale astro hog using the same thing. I used Randolph dope also. That Lazy Ace is going to take quite a bit of lumber, covering, and paint to get completed so using a full scale source for components is a great way to go.

I love the way dope performs, but I really want to try and avoid it. I may stick with Poly-u but we shall see. I may end up using dope.
I want to track down some spoked wheels. I have heard baby buggies are a good source. I guess I will troll fleabay.
So far I do not have much money invested. The balsa was just around $120. Lone star has great prices.

Well, I got most of the Stab built. I decided to cap strip the ribs to give the covering more support. It will maintain the airfoil better with less sag. This thing is huge, 540 sq. in.! The Stab is bigger than a Q-500 wing.
So I have not recieved my wood yet, (I used stuff I had lying around to build the stab) hopefully Monday. I did get my covering material from aircraft spruce. Wow! I got a lot. I ordered 10 yards X 60' . I should have plenty. It looks very good. Very tight weave and it should be quite easy to work with. I am excited about the fabric and I certainly chose the right product here. I only spent $32.50 for all of that covering!
Sorry for the big picture. Not sure why it did that.

I am still waiting for my wood to show up. It should be Wednesday by the tracking. I did try the fabric as a test and it worked wonderfully. I think I may use Balsarite to adhere it and then Poly -U to seal it off. I want that yellow rustic look. I will do some tests to get the color I want.

My balsa showed up today from Lone star. It looks great! It is wonderful to see them up and running again and able to provide such great service.
hopefully I will get a little more progress tonight. i want to finish the stab and then get started on something else. Not sure which. Maybe the Fuselage?

I have the Stab finished now and am moving on to working on the wings. Drilling holes to accept tubes and all.
If anyone has experience with this plane, I would like to get a gas engine suggestion. I know the G62 was used on them, but how about any of the newer gas engines?

The Super Lazy Ace has been powered by a wide variety of engines, big hp differences. It depends very much on what flight profile you plan. The other issue is weight. If you can put off the engine selection until you know how much nose weight you need, you are bound to make the right choice. A G-62 will be on the high side of what Chuck would recommend (by what I remember), but should be an excellent choice.

Have fun!

Well, I have gotten some stuff done. Half of the top wing with removable outer panels on tube. And the Stabalizer. Going together smoothly at this point.

Keep the progress reports coming. I liked what I have seen enough to purchase my set of plans from the net. So I should be able to start on mine mid summer!

Lazy Ace is a GREAT flying machine. I built my first one in 1982 and she is still flying. I am about to start the build of the Super Lazy Ace kit that I bought right from ole Chuck himself from Texas in 1995. That kit has the wire gear, all wing ribs, full plans and plywood formers. I am not sure yet if I will build light (monokote cover) or if I will use scale covering and go with a larger gas engine. If I go light - I may put the Saito FG-36 in her. I have flown the 76 in (regular Ace) with a .60 - but for real pleasure it takes a 1.20 ! A lot of nose ballast is required with a .60 on board.

What happened to the project? This winter I got my Super Lazy Ace out and started to recover it. I had so many different engines on it that cowl is full of holes. Anybody know where I can get a new cowl? Its being covered in blue and yellow kinda like a Stearman in military colors. Originaly built back in the 80's from Chuck Cunningham plans. This was my first scratch build, so I have some feelings for it.

You will love that Lazy Ace. I built one many years ago, covered in Ceconite (lightest grade from Spruce Specialties) but use Hobby Poxy paint for finish, turned out great. Powered mine with an old Quadra 35cc.

Know this is really old but was yours a 96" Super Lazy Ace with the Quadra 35cc, if so do you think a 40cc twin DLE will fly it reasonably well?

Thanks,
Wayne
