Spoiler and SpoilerSaver™ Assembly
Prior to proceeding the wing center section should be completely covered with AeroFILM or AeroFILM Lite. Additionally,
covering and balsa plug should be removed from the underside of the wing to expose the spoiler servo mounting pocket.
Covering has been removed from the assembly photos simply for clarity. Please note: If you have elected to rubber band
on your wing the spoiler cannot be made functional, return to these assembly steps when you’ve built up enough
experience and confidence to fly with the bolt-on wing option and wish to make functional the spoiler.
1.
Locate the spoiler set aside previously during the wing center section assembly (sheet 10/21) and 1/16 in ply
cross grain spoiler doubler SP3 (sheet 20/21). Bond SP3 with medium CA glue to the recesses in either side of
SP2 to stiffen the spoiler assembly.
2.
The spoiler assembly is etched with the following text “UNDERSIDE TRAILING EDGE BEVEL 45 DEG” along
the edge that the spoiler is etched with this text sand a 45 degree bevel using a sanding bar or sanding block.
See illustrations below.
3.
With the spoiler assembly properly sanded cover spoiler in AeroFILM or AeroFILM Lite.
4.
Install 1/16 in. ply spoiler control horn SP4 (sheet 20/21) to the underside (etched) of the spoiler assembly with
the round side facing the beveled edge and the sharp side facing the leading edge as illustrated below. Note
that a spare part SP4 has been provided on sheet 20/21.
