mounted to get it away from the dirty
air behind the wings. The stabilizer
and rudder are built-up and covered in
transparent red. The stabilizer can be
permanently installed or left removable
The vertical fin has a nice recess so the
built-up rudder fits with no discernible
gap. All of the woodwork in the fuselage
and the pushrod guide tubes are
installed at the factory, and the canopy
snaps into place for easy battery access.

E-flite kit manuals are typically among
the best in the business. Unfortunately,
that wasn’t the case for the Mystique.
There were a few errors and omissions
that I’ll document.
I used Zap thin and medium CA and
Z-Poxy 15- and 30-minute epoxies, available from Frank Tiano
Enterprises, to build the Mystique. Please ensure you have
adequate ventilation while working with any chemicals.
The first step in constructing the Mystique is preparing
the wings. The all-wood, built-up construction appeared to
be sturdy, but lightweight, and the flaps and the ailerons are
prehinged. The four low-profile, digital wing servos were all
that needed to be installed. I thought it would be easy.
I read the entire manual and decided to install all of the
control horns with one batch of epoxy. Before mixing any
epoxy, make sure you have alcohol and paper towels handy.
Any epoxy runs or fingerprints on the white fuselage or wing
covering will stand out like a sore thumb.
After test fitting all of the horns and cleaning up the slots, I

scuffed the gloss finish off of the control horns’ gluing area. I
used a toothpick to pack some epoxy into the slots and glued
the control horns into the ailerons, flaps, and the rudder.
While the control horns were drying, I removed all of
the servo hatches and used 15-minute epoxy to attach the
servos to the hatches. Make sure to scuff the gloss off of the
servos and rough up the gluing area on the hatch with 80-grit
If you ever need to remove the servos you can slightly bow
the hatch and the epoxy typically will break loose. Some
builders use double-sided tape to attach the servos, which
When it came time to install the thin Spektrum A7020
digital servos in the wings, I encountered my first problem
