Unlimited flight attempts, your best single duration is your score.
Under 18 years of age compete in Junior/Senior class, over 18 flies in Open class.
Report your score, name, age class, and whether you flew indoor or outdoor at SkyBattlePostal@gmail.com
Model must be “built to the plan” but minor alterations are allowed, like a different prop, any covering material you like, any size rubber motor, etc.
This is a "postal" contest, where pilots fly their models at their home field, and report results to headquarters by email.
The "PuzzlePlane Bomber" is the official 2023 OFFC One-Design model!
It was designed by Bill Watson. Howard Littman markets an excellent laser-cut kit. You can build yours from free plans instead, if you prefer.
