Flap Controller - Part 2

This blog covers the installation of the flap controller

Overview
The flap controller supplied by Aircraft Extras FPS Plus NT allow's automatic 3 position with auto retraction of the flap by a simple tap of the flap switch. To tidy up the wiring the cores all were run in loom tube and it was decided to install the electronics into a larger box to allow the final termination to be hidden.

Manufacture

Ready to install

A plastic jiffy box was selected and the original cover used to match drill mounting holes for four [4] 6-32 screws in the base. Once drilled the surplus area behind the PCB was cut from the case to lighten it a little.

Two 0.020'' 2024-T3 aluminium lugs were manufactured then drilled to take four [4] 5/32'' pop rivets each. These were placed on the box, drilled and after painting [front only] pop riveted to the plastic case with the 5/8'' lighting hole's added.

The PCB was fitted using the original standoffs & 6-32 screws as required - all screws were treated with small drop Loctite thread lock at assembly.

Once completed it was pop riveted to the longeron using 5/32 x 7 mm pop rivets. 

Finally all the loom tubes were installed into 9.5 mm holes drilled at assembly completed the necessary preparation for termination.
