The LT- 40 is a Sig ARF spanning 70 inches and powered by an O.S.
.55AX, t wo-stroke engine turning a 12 x 6 propeller. The model also
has Maxford USA .40-size fiberglass floats. Bill is the owner of the
model. After it crashed, Eric revived it.
Eric made extensive fuselage repairs and reattached all tail
feathers. He also removed all of the MonoKote and recovered and
applied new Sig Manufacturing graphics. More repairs were made to
the wing and float struts.
Repairs were successfully completed in March 2012. Its maiden
flight followed, using traditional landing gear with tires.

‘solid of least resistance’ using a ‘well-fed trout’ as a guide. His original
drawing looks very much like a modern, fully symmetrical airfoil. Curious
to see how well it would fly, I decided to design and build a model using
Sir Cayley’s airfoil shape for the wing ribs.
“Construction is all wood with fully sheeted wings and tail surfaces.
With the O.S. . 61 running at full song, this 6-pound airplane has
aggressive vertical performance and is notably quick on the straight and
level. Wing loading (550 square inches with a 62-inch wingspan) is a bit
high, so low-speed performance is less than inspiring.
“Conclusion: this 16% airfoil, although speedy, is not the fastest
shape around. Don’t tell George …”

Thomas’s model is powered by an E-flite Power 32 electric motor
spinning a 13 x 6. 5 APC propeller. The electric components include
Hitec HS-225 servos, a Spektrum AR500 receiver, and a Castle

built this CMP P-51D Mustang.
A Chinese SV 26cc gas engine powers this 72-inch wingspan
model using a 16 x 6 propeller. The Mustang comes with flaps and
Ralph added electric retracts. Carolyn Schlueter took the photo.

An additional note: If you’re not into gas engines, I also flew it with an
O.S. . 90 and did not feel that it was underpowered swinging a 14 x 6
