    Default Super Pacer (Bushmaster) Mod

    My winter projest is to mangle my perfectly good Pacer, by installing the Bushmaster STC.

    This STC modifies the wings to a super heavy duty Super Cub wing. This wing will have four feet of spar reinforcing at the lift strut attachment, more reinforcing at the new jury strut, 13 ribls, double drag wires and compression struts in the new outter bay.

    My first step was to make all the wing reinforcing pieces out of .050 aluminum.

    Second was converting the Pacer aileron to 102 inch Super Cub ailerons by adding 30 inches.

    Next step was removing the Pacer wing and removing fabric.

    Next, buck hundreds of number 5 rivets installing the spar reinforcing at the new lift strut location. SC attachment brackets are used in the forward spar and the front Pacer attachment in moved to the rear spar.

    Drag wires get moved and new compression struts are added.

    Your can see how the drag wires are doubled for added strength in the outter bay.

    This wing will be much stronger than a typical Super Cub wing.

    Beautiful workmanship. Any estimate of the weight gain? My guess is your stick conversion probably reduced more weight than you will gain.

    Thanks,

    I hope that the weight gain will be under 100 lbs. I have a few ideas where I can cut weight....Weight and cruise speed are the two factors that I am curious about.

    Left wing flaps are on today's project list.

    Curious as to the net gain of doing the STC?
    Increased GTW?
    Higher cruise speed?
    What?

    Looks good!

    Question: what's the reason for the extra drag/anti drag wires in that bay?

    Unless I'm thinking about something else, MGW stays the same and cruise speed decreases slightly.

    But what you gain is true supercub short field capability with a bunch of usable cabin space and room for 4 folks. And I hear that they are some sweet flying airplanes, too.

    Exactly,

    Plus it keeps me out of the house and out of trouble this winter.
