Flap fitting

Posted on by

Pretty straighforward fit up here, flaps are bolted to hinges and the fuselage holes are enlarged and shaped to receive the rod end bearings/rods as the flaps move thru their range of travel. It was fun to use the electric actuated flaps for the first time. The rods need to be shortened 1 1/4″ to achieve the desired start and finish location.

I need to find a flap position transducer for the Dynon Skyview system and install it. I think that gauging flap position would be difficult to do without some sort of position transducer.

The flaps sit nice and tight with the top wing skin in the up (zero) position. There is a 1/16″ gap on the bottom fuselage / flap intersection. I will try and tweek this gap and close it up.

Canopy rear cover strip

Posted on by

A number of folks are going away from using the kit supplied aluminum rear cover strips to fibreglass layups instead. This method complements the use of sikaflex for canopy-frame attachment as once the cove strip is finished, its glued in place with sikaflex, eliminating the rivets and hole drilling in canopy and frame. The construction process is the same as that used for the windscreen fairing, the strips are 6.5 to 7 inch wide and the initial layup of 6 glass layers is easily done in a hour and a couple of batches of resin. Before starting layup, mylar packing tape is used to cover the gap between the canopy and the rear fuselage skin.

The layup is complete and this weekend I will start sanding and filling it before removing from the aircraft. This method is sand and fill tedious but rather easy and stress free compared to the difficulties I have heard of using a metal skin.

ECU Components return

Posted on by

The Precision system comes without any wiring components. After you mount the ECU, coils and PMU, you fill out a wiring order form, complete with all the lengths of the various sensor, ignition and communication cables. Once I submitted that form I was contacted by Precision and asked for the firmware revision information on my various components. Turned out I had old stock on the ECU and PMU and had to ship them back for updates. Today the componets returned along with the completed cables, custom made to my specifications. I was keen to confirm that I had made the correct measurements and that Precision had followed them. I was not disappointed, the workmanship was excellent and everything fit as planned. The attached photos are not finished installation, only a first fitup.
