Tips On Trimming and Flying a Catapult Glider

Now that there are two new indoor catapult glider classes, and there is still an outdoor catapult class, you guys can't use the excuse that your arm isn't any good anymore! Now all you need to do is pick up your old broken Wakefield, or Bostonian motors, and make a little loop for your catapult (1/4" dowel works nicely) and tie it on, pick up your glider, pull back, and let go! No more running twenty-five yards, lunging and throwing your arm out of its socket all day long, then complaining you're not getting any height. No, now all you need to do is add another loop of 1/4" tan II and let fly!

Keep in mind, many of these tips will also apply directly to a hand launch glider, in fact that's where many of them came from. So if there are any other brave souls that have caught the age old, highly contagious, HLG disease, keep your ears open.
