A great day this morning. Our Rebel made his first flight in Koblenz-Winningen. Everything was perfect. The engine ran smoothly and with enough power. Wow! This was a nice reward for a long build and long time doing the documents. Due to our FAA first flight has to be performed by an very experienced pilot. […]Continue Reading...

In the meantime I also made the strut fairings. They are fabricated from 0.015″ aluminum as per the manual. Getting them in a proper shape is a lot of work. Took some time to get them in good fit …. but time was not an issue waiting for the documents …Continue Reading... Comments Off on Strut Fairing
We are waiting and waiting for our OUV-assessment. It’s really frustrating having a ready to go airplane and waiting for the bureaucracy. Meanwhile I am doing minor things, which where originally planned after the first start. Today I fabricated a fairing for the left wheel. As suggested by other builders I used Lexan (or the […]Continue Reading... Comments Off on Waiting and Waiting for the OUV – Gear Fairings
For insulation and soundproofing I used a aluminum air bubble film foil. This weighs nearly nothing and should give good insulation. Fixing of the foil on the back is with Velcro-strips. My wife wants another look so I will be cover the foil with car roof lining materialContinue Reading... Comments Off on Foil for rear wall
Since I am still waiting, I started doing minor things. One of these was a rear wall, which I wanted to have to make sure no luggage goes into the back. I fabricated this from Airex C70 and glassfibre. Very stiff and very lightweight. Picture shows the raw wall, it will be cased later with […]Continue Reading... Comments Off on Rear Wall
Long time no post! There is not really much left to do. The plane is ready to fly, but the bureaucracy drives me crazy. I am waiting for my reviewer from the OUV (German EAA) to finish his assessment. Progress is slow and summer season is coming ….Continue Reading...

The inspector advised to install an flap indicator. With the standard setup it was not possible to make appropriate markings. An aluminim strip above the installation makes it possible to mark the flap positions. The Rebel standard positions are in increments of 6 degrees. For the sake of simplicity I marked the positions in 10 […]Continue Reading... Comments Off on Flap Indicator
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
With support from the local aircraft works, I did the weighing of the Rebel this morning. I am quite happy with the results: Although I installed a ballistic recovery system the total weight of the Rebel is 382 kg. I had 176 kg on every wheel in the front and 30 kg on the tail […]Continue Reading... Comments Off on Weight and Balance
I received the ballistic recovery system from Junkers Profly and started installation of rocket, container and harnesses. The picture above shows the holding point for the backward Aramid harnesses. Picture below shows the harnesses from above. I will protect them with 0.015 Aluminum strips later on.Continue Reading... Comments Off on Rescue System Harness
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
As required by the VLA and EASA specifications I needed to install a fireproof identification plate. I decided to install it near the left fin. For marking I used a fireproof stainlees steel plate engraved by laser. This laser engraving is available via Internet.Continue Reading... Comments Off on Identification Plate
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.
As requested by our german FAA (LBA) I had to electrically bond every moving part of the plane. This sounds rather superfluous in an all metail aircraft, but it’s probably the best to be on the safe side. The picture shows a small wire connection between elevator and horizontal stab. The wire will be covered […]Continue Reading... No Comments.
We reserved a registration number for the Rebel: D-EREB. We used a printed foil to put the numbers on the plane. The plane will be painted later, but to get the permission to do the first start, we need the plate. So we put them on and they will be redone later after painting. […]Continue Reading...

A great day today! The engine was started for the first time. It all went perfect. The engine started immediately. All engine values showed absolutely great values. Several security precautions were made. We fixed the Rebel at the car (in case of a break failure). Of course a fire extinguisher (CO2) was on hand. But […]Continue Reading... No Comments.
Fuselage, wings, wing tips and tail unit were put together at the airport. Now it looks like a true airplane, ready to start off in the air. But a lot of tests and permissions to get before the first flight will take place.Continue Reading... No Comments.
Same trailer was used to transport the wings to the airport hangar. It was only possible to carry one wing at once. In any case it was a safe position for the wings and both reached the airport without any problems.Continue Reading... No Comments.
This is the new home of the airplane in the hangar at EDRK. The hangar has a rotary ground, so putting it out is easy.Continue Reading... No Comments.
Rolling off at the airport. We build a special ramp and it was an easy job rolling the fuselage down the trailer.Continue Reading... No Comments.
We had a safe arrival at the airport Koblenz (EDRK). Fuselage was absolutely stable on the trailer and didn’t move at all.Continue Reading... No Comments.
An important date today: Fuselage is transported to the airport. We could use a trailer from a member of our aeroclub. The trailer is 9 m long and really good for transporting the Rebel. Transport took place early Sunday morning, so there was no traffic and we could slowly do the 20 km to the […]Continue Reading... No Comments.
Trailer is prepared for the transport. It is a big trailer, nevertheless needs some additional installations to put the wheels on. Crane was very helpful to get the fuselage on the trailer.Continue Reading... No Comments.
Before the engine even had a single minute on it, I had to do a service bulletin from Rotax. The carburator floaters had to be changed, since there were production errors. Easy job if the carburator is freely accessible.Continue Reading... No Comments.
Again we used the opportunity of the crane to check the amount of unusable fuel in each tank. The Rebel was put into the worst fuel conditions, which means nose down. Following values of unusable fuel were measured for each tank: X-achsis shows angle of attack (-9° = ground position), Y-achsis shows unusable fuel […]Continue Reading... No Comments.
Having a crane available in the workshop, I put the Rebel to the expected maximum positive angle of attack. So I put it into 15,5 degree positive angle and measured the fuel flow. We put a minimum (5 liters) into each tank and measured the flow. Left tank delivered 24 and 32 […]Continue Reading... No Comments.
