The laser-cut kit and hardware are included
with the Super Ringmaster. The model
includes full-size plans for the wing.
The glow-powered Super Ringmaster has limited space for a fuel tank.
A 2-ounce tank was installed and plumbed and a Brodak . 40 engine was
Here is a suggestion you might consider before installing
the bellcrank: For the leadouts, use the holes closest to the
mounting screw (21/4 inches from hole to hole). For the
pushrod, use the hole closest to the mounting screw (5/8
inch from screw to hole). This will slow the control and
help with flight stability.
Stabilizer and elevator construction will not be a
problem. Follow the instruction manual and you’ll be fine. If
you plan to fly this model competitively, I suggest replacing
the wooden control horn with a nylon one. Make sure the
pivot hole is 5/8 inch from the hinge line. If you’re not flying
competitively, the wooden control horn will work fine.
Throughout the years, Ringmasters have had one thing
in common. When built according to the plans, they have
more control than you need, unless you’re flying Combat. In
competition, the airplane is stable and smooth with plenty
of control to easily perform square
loops and Figure Eights.
Pay careful attention to one area
during the fuselage assembly. The
engine compartment is not like a
Nobler or Thunderbird. The maple
mounts do not fit flush against the
inside fuselage, but are secured
through the firewall and first
bulkhead. The instruction manual
walks you through this process. After
you have ensured their alignment,
epoxy the mounts, firewall, and first
bulkhead in place.
Fitting the wing into the fuselage
requires patience. This procedure is
one of the most important parts of the
construction sequence. After you’ve
retrofitted the wing to the fuselage, secure the fuselage to
the building surface with the wing in position. Make sure it
is centered on the thrustline.
Check to confirm that it is square using a seamstress tape
measure. Pin it to the center of the tail post then position
the wing until you have the same measurements to each
wingtip. Spot glue it with CA adhesive and allow it to set
for a few minutes. Reinforce it with epoxy and give it at
least three to four hours to cure.
Before installing the stabilizer and elevator, finish the
fuselage with the top and bottom skins. It will take some
fitting and sanding to be ready for the next step. To install
the stabilizer, align it with the front wing then measure the
