Frequently Asked Questions About the Flyin' King
Answers by Bruce Tharpe
Q: The Flyin' King kind of looks like a Kadet Senior.
Is it the same thing?
A: At first glance, it may bear a resemblance because it
has a high wing and stick construction. I used to work for
Sig and have great admiration for the Senior and its designer,
Claude McCullough. It's a supreme example of lightweight
stick structure. However, the FK is different in many ways.
The FK is bigger, beefier, and can take bigger engines.
The FK has ailerons and flaps. The FK is designed for easy
taildragger conversion. The FK fuselage is actually much
easier to build. The FK's airfoil is semi-symmetrical, so
it's much more aerobatic and can handle more wind.
Q: Does the wing have polyhedral?
A: Yes, the center section is flat and the outer panels
each have a bit of dihedral. This gives the FK a bit of
extra stability and its own "style".
Q: That one-piece wing is pretty big. Can it be made into
a two-piece wing?
A: Yes; I've seen it done, but it will add weight and you're
on your own as far as the engineering. There are no instructions
in the kit on how to do this. If you're pressed for room,
I think a smarter solution would be to clip a rib bay from
each outer wing panel, bringing the span down to about 72
Q: Would the Flyin' King make a good electric conversion?
A: I think all of my designs are good candidates for electric
conversion because they are light, have lots of wing area,
and have lots of room for batteries. Electric fliers seem
particularly drawn to the FK, so BTE now offers a
with motor, ESC, prop, and installation parts tailored
specifically for this design.
Q: How big is the cabin area?
A: The inside dimensions of the cabin are 4" wide x
7" tall x 16" long. Some of that is taken up with
radio equipment, but there's plenty of room leftover for
two pounds of candy!
Q: How much weight (payload) will it carry?
A: I haven't loaded one to the max, but my best guess is
that five pounds would be no sweat. Ten pounds would be
manageable with good piloting technique. If you plan to
carry a payload, I suggest replacing the stock landing gear
with the heavy-duty version.
Q: I'm thinking about towing gliders. Where should I
mount a hook for the towline?
A: The typical spot seems to be on top of the fuselage,
just aft of the wing. I've collected a lot of info on aerotowing
over the years and will share it with those who are interested
in trying it with the Flyin' King.
Q: Are standard servos okay?
A: Yes, but I've learned over the years that standard servos
without a ball bearing on the output shaft can develop excessive
play after many flights. Sometimes they're very sloppy right
out of the box! Sloppiness in the flight controls can lead
to flutter and crashing with any model. I highly recommend
ball-bearing servos, and if you have a heavy-duty one, use
it on the flaps.
Q: What kind of floats do you recommend for the Flyin'
A: You need floats that are about 45" to 48" long. My top
recommendation is the Great Planes float kit for their .60-size
