Fabricating the wing fairings was a time consuming job. Lots of checking and reshaping. Due to the ballistic recovery system harness at the front wing connection it has to be a little big thicker at the front.Continue Reading... Comments Off on Wing Fairings
Inside the ailerons the screws need to be secured via cotter pins. This is really a painful job. The size of the opening is one inch and the nut is not really reachable. A pliers with a 45 degree head is the solution to solve this. Nevertheless putting 6 of this cotter pins into the […]Continue Reading... Comments Off on Cotter Pin in Aileron
Picture shows the flaperons in the Full Flaps down position. Again I got a deflection in the suggested range from Murphy (15 degrees or 3 inches). Looks really great when the flaperons are down on the whole wingspan. I am curious how this will work in flight.Continue Reading... Comments Off on Flaperons Down
Picture shows the flaperon deflections. The deflections are in the range as suggested by Murphy. I measured 3.5 inches up and 3 inches down.Continue Reading... Comments Off on Flaperon deflections
Flaps have been mounted these days. Now the rebel is in principle ready to fly. Of course some fairings are missing. But before we can do the first flight there is of a bunch of documents and tests to be performed. It will take some months to get the “Vorläufige Verkehrszulassung” from our LBA (=german […]Continue Reading... Comments Off on Flaps Mounted
Here you can see the connections between the fuselage tube and the torque tube inside the wings. Via this connection the steering commands are transferred into the wings. As nearly everywhere in the Murphy Rebel this is a really solid connection, which you can trust.Continue Reading... Comments Off on Torque Tube Connections
Although the ailerons were the first parts to build, I waited with the covering until now. So it is one of the final steps, but its time to do this. Since the material delivered with the kit (Polyfiber + chemicals) was already more than 10 years old, I decided to acquire new material and chemicals. […]Continue Reading... No Comments.
I installed a second landing light at the left wing. The picture shows the finalized installation at the end of the wing, just in front of the wing tips. The next pictures show the fabrication of the lights. First step of the installation: The front of the Led Light is unscrewed. Two aluminum sheets […]Continue Reading... No Comments.
The installation of the right landing light is done. I fixed the plexi with rivets and sealed it with Sikaflex 295uv.Continue Reading... No Comments.
This picture shows the installation of the landing light inside the wing. The lights I used was an inexpensive part (29 Euro). It contains a high power led and provides more than 900 Lumen with only 10 Watts power consumption. 900 Lumen is the light a typical halogen light with 50 Watts provides.Continue Reading...

The plexiglas front of the landing light needs to be bend to match the wing shape. I prepared a special moulded part from wood. Putting the plexiglas into the oven with 170 degree celsius and you can have the plexi in any shape you want. The first companies where I ordered plexiglas from provided different […]Continue Reading... No Comments.
I was not sure how to install landing lights. My first idea was to put it into the tips. But after some consideration I decided to install it at the end of the wing.Continue Reading... No Comments.
The picture shows the epoxy system we used, all from R&G Faserverbundstoffe. Good stuff, probably much better than necessary for the simple, unstructural parts we had to make.Continue Reading... No Comments.
We acquired Nav/Strobe/Pos Lights from AveoEngineering. Great lights. No additional box required, no shielding of the cables necessary. The seem undestroyable and come with a lifetime warranty. With the epoxied position at the wings if has a nice shape.Continue Reading... No Comments.
To fix the stobe/position/nav lights at the tips we need to do some epoxy work. Resin with micro-ballons worked well. After sanding a nice fixing plate for the lights is ready at the wings.Continue Reading... No Comments.
In the end we had a nice wing tip end. Ready for priming and painting. Since we will mount the tips with screws, it is possible to remove them, so priming will be done when the whole airplane is painted.Continue Reading... No Comments.
Last layer of the fibre glass work is a special peel off fabric. It gives a nice finish and prevents from sanding the otherwise waxy surface.Continue Reading... No Comments.
Second step is to lay fibre glass on the end. We used 3 layers of light fibre glass and gave special attention to get nice rounded corners.Continue Reading... No Comments.
First step of the fibre work at the wing tip is filling the gap with epoxy mixed with micro-ballons.Continue Reading... No Comments.
The lower end of the wing tip needs to be trimmed and glued together with epoxy resin. First picture shows the unglued end with a wooden stick inserted to get a nice end. As described in the manual the tip “droops” a bit at the lower end.Continue Reading... No Comments.
Wing Tip is installed on right wing. The quality of the wing tip is much better compared to the rudder/elevator tips. Not much to rework. Only modifications I have to make is a appropriate place for the nav/strobe/pos lights.Continue Reading... No Comments.
The crane was very helpful putting the wing into the right position. He is lifting very slowly and so it much easier to align the 1 degree dihedral.Continue Reading... Comments Off on Crane Lifting Wing
The left strut is cut and put in place. I am happy that everything is in the right length. Doing an error here would be bad. Getting another strut would be hard and expensive.Continue Reading... Comments Off on Left Strut Cut
A detail of the back fitting. One 1/4 bolt which holds everything together.Continue Reading... Comments Off on Detail of back fittings
These pictures show the front wing fitting in detail. As you can see in the second picture, there is a gap between the fittings and the fuselage attach points. As pointed out in the manual, the gaps on both sides need to be filled with spacers or washers.Continue Reading... Comments Off on Detail of left front wing fitting
The right wing is mounted. The right side was much easier, perfect fit. The holes where all aligned. So from the right to the left wing tip I have only 4 mm difference.Continue Reading... Comments Off on Right Wing Mounted
The wings need to have 1 degree dihedral. My electronic level again helped a lot. Everything is perfectly in place now, the strut comes next.Continue Reading... Comments Off on Setting Dihedral
Today I started mounting the wings. Left wing was first. I constructed two scaffolds, where we put the wing on. The crane was used as safety measure. I knew that the front fittings were a little misaligned, so it was a lot a fiddling around. Finally I got everything installed and the wing was […]Continue Reading...

An important milestone is reached! Both wings are finalized and waiting in the wingstand for future installation. You can see plastic tubes (normally used by electricians) in the middle of the wings. These will be used for cable installation.Continue Reading... No Comments.
