Most FAC Jet-Cat models can be flown in Winterfling.  There are many competition-type catapult gliders which qualify also. 

This is a "postal" contest, where pilots fly their models at their home field, and report results to headquarters by email.

Postal Contest rules:

 

  • Winterfling is an event for FF Catapult Launch Gliders with a 13-inch maximum wingspan.

  • Official flights must be made within the contest flight-window.

  • Unlimited flight attempts, the total of your three best flights is your score.

  • Under 18 years of age compete in Junior/Senior class, over 18 flies in Open class.

  • All official flights must be hand-catapulted, 6" launch-stick length maximum.  Any size rubberband is OK.

  • Models must be all-wood, with no carbon fiber or folding wings.

  • Report best 3 flight durations (your total score), pilot age, and model name at SkyBattlePostal@gmail.com

Choose a good glider and get it trimmed to fly well.  Then wait for

the contest calendar-window and fly your best 3 flights.  Send the

data in to SkyBattlePostal@gmail.com and see how you did!.

Ask questions and report your results to
SkyBattlePostal@gmail.com

Please include pilot's name, best flight time, and age category you are competing in.
 

 

​Each pilot may make unlimited attempts to get his or her 3 longest flight times. 

 

  • Use a stopwatch or smartphone timer app.

  • Timing starts at model launch and stops when the model touches the ground, goes out of sight during flight, or lands on any structure, tree, etc

  • No entry fee.

This type of model airplane has been
around for over 100 years!

Winners will be announced

Entries with no age info are placed in Open category!

Skybattle contests are presented and sponsored by The Secret Sky Squadron, a shadowy group whose members are shrouded in mystery. 

The Secret Sky Squadron promotes and supports old-school model aviation among air-minded pilots young and old.  Skybattle postal contests are thinly-veiled plots to ensnare new recruits into this sport...
