Bill Welle has developed a neat
autogyro conversion kit for his
Lo ’N Slo small-field flyer.
You can make the fuselage and tail
surfaces a shape that pleases you and
move the equipment as needed to
achieve the correct CG location. When
that is done, go enjoy some nice Rogallo
If you would like a larger version of
the diagram, it is available for download
from my website in the the Techniques
and References section. Also available
from the website are plans for a micro
Rogallo wing model by my brother,
Ralph, called the Cootie. It is great for
calm-day or indoor flying. My website
address is listed in the “Sources.”
Thanks for sharing Rogallo Rick with
us, Christian. It is a nice reminder of
how well suited the Rogallo wing is to
small-field model aircraft.
Lo ’N Slo Revisited
Back in the February 2014 edition
of this column, I shared with you a
nice foam board model by Bill Welle
called the Lo ’N Slo. This is a larger,
slow-flying RC model that is well
suited to our small-field venues.
Bill is an autogyro enthusiast
and has developed a slick, strap-on
autogyro conversion setup for his Lo
’N Slo model. You simply remove the
wing that is held on with rubber bands
and replace it with the autogyro setup.
When in place, power up the model
and you will enjoy the flying qualities
of a twin-rotor autogyro.
The plans and full-size parts templates
for the Lo ’N Slo can be obtained from
my website in the downloadable plans
section. I have also added the drawings
and parts templates for the autogyro
Thanks, Bill, for sharing your nice
small-field models with us.
