4th of July Special from Wowplanes


Hello guys,

Hope all my American friends had a wonderful 4th of July. I certianly did.

I had an idea to design something special for Independence Day and maiden it on July 4th. Well I ran out of time and it was not quite ready to fly, but it was good enough for a show & tell. So I took it to the club picnic on July 4th and here is a picture.

It is 102" span and is an original design. I wanted to make something big, easy to build, easy to fly, streamlined and low drag, and here is what came out.

I went about it somewhat differently this time. I had no idea of the final shape so I first built the wing, then tried several shapes for the fuselage in CAD until I liked one. I did the same for the tail.

The paint job is not finished yet. I think I will add some blue to the H.Stab and some design and color to the V-Stab too.

Would you like to see a build thread?

The inspiration for this baby came from the recent 4th of July Independence Day. My plan was to maiden her on the 4th, but I simply ran out of time. However, I got her in shape for a show & tell, and picture taking, at our club's 4th of July picnic.

I started without any idea how the plane would turn out. I have always wanted to do an "original", I wanted something big, something that would look impressive in flight, something sleek and aerodynamic with low drag, something that would be aerobatic, something that would not be too complex to build.

One thing I learned very early, is that, an original is much more difficult to design as compared to a scale model. I had no 3-views, no pictures, and no truckloads of documention to go by. Everything had to be imagined and created from thin air. Of course I did use aeronautical engineering principles to arrive at the proportions of the model, and ensure that she will be a good flyer.

I started by building a constant chord wing, no dihedral, semi-symetrical airfoil, psuedo-Fowler flaps, and ailerons. The servos and pushrods were to be concealed. The wing span ended up at 102"

Here are some pictures of the build sequence.

Nice looking sport model, there. Not scale, but very nice looking.

You might want to consider moving the thread over to the Sport Model area, especially if you plan on kitting it one of these days. They would be interested, I bet.

Hi Thomas,
Yes it is not scale, but there are no builders over there at the Sport Model area, and this will be a builder's kit.

You might be surprized. There are a number of builders over there, just like there are a number of folks here who are into ARFs.

A quick scan of the Sport Planes forum shows that there are at least 12 threads devoted to kits, plans built and scratch built models on the first two pages alone.

Who knows....you might inspire more folks to build over there.

I continued with building the wing. A large 102" spam wing built as a one piece may be more than the average car or van can handle. There is no reason why it could not be built as a two piece wing. The mid wing can be permanently glued into the fuselage and the outter panels slid over carbon fiber or aluminum tube with dowels for registration. I have a van with a 12 ft bed, so I did not feel it necessary.

Since I have no idea how to now this thread and have not heard from anyone who does, I guess I will have to continue here until then.

Thanks for the heads up. I will pay extra attention to it. Might have to change the hinge method if that happens.

Well, it is time to start building the fuselage. It comes in 4 parts, 3 of which make the fuselage and the 4th one makes the cowl.

I continued with building the fuselage. Some of the pictures are not in sequence and were taken after the final paint, but I hope you will get the idea.
