Test Flights
The glider will need some nose weight to balance properly in flight. Use a small amout of modelling clay
(pea sized) as a starting point.
The initial balance point should be 3-1/2” (89mm) back from the root leading edge. That’s where the
leading edge of the wing meets the fuselage. Choose a calm day outside for your test flights.
Throw the glider with the wings level and the nose slightly down. Try to throw it just fast enough for it to
glide away from you steadily. If the model dives downwards, remove a little clay. If the model climbs and
then dives (stalling), add a little more clay. Aim for a fairly fast glide with a nice smooth flight.
For throw launching you can try tilting the model to the right (if you are right handed) and give it a hard
throw pointing upward at about 20 degrees. Keep adjusting your throw and nose weight until you get
some nice glides.
Catapult Flights
Warning: Never point a catapult model at, or near, anyone when launching. The glider will be
going fast from the launch so be very careful!
Catapult launched gliders are tricky to fly but great fun, too. For the first catapult launches use just one of
the 1/8” rubber loops. Hold the catapult in your left hand (do the same if left handed). Hook the rubber
loop onto the glider. Pull the glider back, tilt it about 40 degrees to the right and point upwards about 30
degrees. Holding the catapult still, let go of the glider.
The jet will arch up and to the right, hopefully the wings will level and it will glide down. Watch which way
it turns. After several tries add a very small amount of modelling clay to the left wing tip. This is to try to
make the glider go into a gentle left turn as it slows down after the launch.
Another trimming tool you can try is to cut a small rectangle (1/2” x 1/4") of thin card. Crease it slightly in
the middle and glue it to the bottom of the rudder on the left side. This is a rudder trim tab and is used to
help make the glider go into a left turn at the top of a stronger catapult launch.
To get the best out of any catapult glider we can recommend searching “catapult launch gliders” on
YouTube. Have fun!
