Tug tow hook can be anywhere within the yellow circle. Not too far from the C of G and through
the thrust line.
Glider tow release
My Favourite , the "Peter Averill" Tow release.
Glue the nyrod into the hole, but do not allow it to protrude into the towline receptacle hole. The
actuating wire is a 1.5mm piano wire from the servo.
On the servo, use the innermost hole on the horn. Closed position is as shown with the servo arm in
a "locked" position to gain mechanical advantage.
Use a 3kg/cm or greater servo
When installing into fuselage, the area around the slot may need reinforcement with ply or glass.
Could also use "servo eyelet"
Glider tow hook can be anywhere within the yellow circle. This one is the Engine bearer type.
Towlines
Material - You can use any of the following:
F3B Winch Line, Thick Whipper snipper line, Brickies Twine or a thin rope.
Length:
21 to 45 metres is in the range, but optimal would be around 36 metres.
Note: the Glider end of the towline is often "floating" about 36 metres behind and below the tug. It
can be prone to catch on fences, power lines or trees. Make a special effort to keep it away from
people and property.
Summary
For the scale Glider pilot, aerotowing has some real advantages, the obvious one being high
launches , up where the thermals are bigger. Even on a non thermal day, flights of 20 min are the
norm. You get to take off and land on a runway, much nicer than dropping into the longer grass...
nice landings top off a nice flight
More importantly, its easier on the model than a winch, none of those figure 9's just after launch, no
huge bending loads on the wings, and no line "birds nests!"
For the Tugger, he will find a purpose for his flying, and his skills will improve by lots of flying
with the TX sticks in unusual spots, and take offs and landings will improve "out of site"
