  • Improved Flap Handle

    Posted on 4. April 2015 by Thomas in Controls, Fuselage, Recent Posts.

    Having nice wooden flight sticks, my wife also wanted an appropriate improved (better looking) flap handle. With the support of a friend in “wood business” I fabricated the wooden flap handle in the picture below. Much better looking, but only experimental builders can afford such a time consuming part 🙂

  • Brakes working

    Posted on 10. June 2013 by Thomas in Controls, Fuselage, Recent Posts.

    After the brakes were filled with fluid, I tested them. I put pressure on it and checked every connection. No leak occured. The parking brake is working well. Even after several days there was still enough pressure in the system that we could not move the wheels.

  • Bleeding Brakes

    Posted on 10. June 2013 by Thomas in Controls, Fuselage, Recent Posts.

      Filling the brakes with hydraulic fluid was a job I often thought of. Having done this never before, some consideration was made how to perform it. In the end it was an very easy job. Take a simple oil can with a small tube, connect it to the bleeding inlet at the bottom and […]

  • Modified Pedal Spring Mount

    Posted on 16. May 2013 by Thomas in Controls, Fuselage, Recent Posts.

      The manual says to insert the pedal return springs into a hole at the side of the motor mount. I did this first, but was absolutely unhappy with this. Very hard to put the spring into this hole and if you need to vary the spring position you need a row of holes in […]

  • Parking Brake

    Posted on 16. May 2013 by Thomas in Controls, Fuselage, Recent Posts.

      We installed a parking brake in the Rebel. There is a very good description available online from Roee Kalinsky (http://www.kalinskyconsulting.com/rvproj/parkingbrake.htm). I copied this design with some modifications.

  • Pedal Positions and Brake Cylinders Fixed

    Posted on 16. May 2013 by Thomas in Controls, Fuselage, Recent Posts.

    I decided to go with 4 brake cylinders. A lot of alignment work to get the pedals totally aligned. Although prepared before I had to wait for this step until the engine mount are positioned.

  • Flap Handle Bolt

    Posted on 26. December 2012 by Thomas in Controls, Fuselage, Recent Posts.

      These pictures show the simple mechanism Murphy uses to fix the flap positions. Just an AN4 bolt which fits into a hole. Just pull the handle towards the pilot and move it to the different positions. Simple, but I like it.   I just drilled the hole for the neutral position here. Others for […]

  • Teleflex Cable Routing

    Posted on 26. December 2012 by Thomas in Controls, Fuselage, Recent Posts.

      It took me some time to find out the best way to route the teleflex cable. I wanted to make sure that my head has enough clearance at the top. This turned out to best the best way.

  • Flap Handle Design

    Posted on 9. December 2012 by Thomas in Controls, Fuselage, Recent Posts.

    The picture shows the flap handle design. I decided to go for a slightly modified standard flap handle . The handle has a modified “hockey stick” design, to keep it out of sight. The handle was then equipped with some wood for better handling. Maybe a rubber cover will be installed over it later.

  • Center Console Ergonomics

    Posted on 4. November 2012 by Thomas in Controls, Fuselage, Recent Posts.

        With the posterboard model of the console we checked the ergonomics. A simple throttle quadrant model was installed as well, so the tests could start. We are very happy with the ergonomics. Everything is well in reach and gives a relaxed flight.

    Posted on 4. November 2012 by Thomas in Controls, Fuselage, Recent Posts.

      We decided to build a center console for the Rebel. Thus we can install a throttle quadrant for the motor. The pictures show the model, built from paperboard.

  • Rudder Pulley

    Posted on 13. October 2012 by Thomas in Controls, Fuselage, Recent Posts.

      I decided to install pulleys at the front and back of the forward fuselage. The angle of the cable is changed by more than 3 degrees, so I prefer a pulley instead of the cable guides as written in the manual. I  used 1 1/2″ pulleys from ACS (05-29725), a cheap solution and much […]

  • Hanger Finally Fixed

    Posted on 13. October 2012 by Thomas in Controls, Fuselage, Recent Posts.

      The hanger is finally fixed. The tubes will be installed later, just before the wings are installed. Other than the instructions in the manual I fixed the hanger with AN3-5A bolts instead of RV-1613 rivets. This has the advantage to be able to dismount, but the main reason is shear load on the hanger. […]

  • Bell Crank Brace Cutout

    Posted on 13. October 2012 by Thomas in Controls, Fuselage, Recent Posts.

      The space between the tube (CC-50 to the mixer) was not enough. When pulling the mixer arm in the highest possible position, the tube touched the bell crank brace. To overcome this I cut (or better filed) a small cutout into the bell crank brace.

  • Bell Crank P/P connection

    Posted on 13. October 2012 by Thomas in Controls, Fuselage, Recent Posts.

      I didn’t like the suggested method in the manual how to connect the tube coming from the control column to the bell crank. The manual suggested to leave off the jam nut. That would mean all the movement in the tube (originating from moving the control column forth and back) had to be covered […]

  • Inside Control Column

    Posted on 30. September 2012 by Thomas in Controls, Fuselage, Recent Posts.

      This is a detailed view of the connection of the two control sticks. This looks very easy but it is a very tedious job to put the spacers inside the column. This job took a lot of time and nerves.

  • Aileron Stop

    Posted on 30. September 2012 by Thomas in Controls, Fuselage, Recent Posts.

      To make sure I do not have interference with the rudder cables, I finally painted and installed the aileron controls. One detail of this are the very simple but effective aileron stops in the base of the control stick.

  • Installing Rudder Cables

    Posted on 28. September 2012 by Thomas in Controls, Fuselage, Recent Posts.

    Finding the best way through the fuselage for the rudder cables is a time consuming job. Lots of climbing in and out into the fuselage. I found this installation keeps the rudder cable rather straight.

  • Color Coding Push Pull Tubes

    Posted on 28. September 2012 by Thomas in Controls, Recent Posts.

    To make sure the P/P tubes are not interchanged, I color coded the mixer, th P/P tubes and the control horns. Thus you must be really dreaming if you misinstall these. I hope my FAA supervisor is happy with that. Isn’t that a nice red color !?

  • Mixer Detail

    Posted on 5. August 2012 by Thomas in Controls, Recent Posts.

    Mixer mounted on the mixer arm. I decided to mount the mixer after the teleflex cable moun (as stated in the new version of the manual). It gives more clearance in the doors, that means the P-P tubes only slightly interfere with the door opening. There was an error in the manual concerning the holes […]

  • Push Pull Tubes constructed

    Posted on 5. August 2012 by Thomas in Controls, Recent Posts.

    The Push-Pull tubes have been constructed today. As mentioned by other builders on the list the length (tube only)  is 26 1/2 and 26 3/4 for my rebel. All the tubes and the mixer are temporarily mounted, to be corrosion protected from inside before riveting.

  • Torque Tube with hanger

    Posted on 1. August 2012 by Thomas in Controls, Recent Posts.

    Today I partially mounted the torque tube, this is more time consuming than estimated.Working over head leaning backwards is hard, espacially when the temperatures are more than 35 degree Celsius in the workshop. Instead of using rivets for the hanger, I will use AN3 bolts. This will prevent sheared rivets been reported by experienced builders. […]

  • Push-Pull Exit with Fairing

    Posted on 3. May 2012 by Thomas in Controls, Fuselage, Recent Posts.

        I did the fuselage exit hole for the elevator push pull tubes this weekend. This was a tedious work. Filing and filing the hole until I get the 25 degrees upward and downward elevator travel. I did it step by step to have the hole as small as possible.   In the end […]

  • Stabilizer Stab Detail

    Posted on 3. May 2012 by Thomas in Controls, Fuselage, Recent Posts.

        This is the first (and probably only) time where normal rivets are used on the Rebel. It was really fun to hammer these down. But nevertheless I am happy all the rest of the rivets are blind rivets. Its a lot easier to pull them. Must be a nightmare doing an aircraft with […]
