At Our Last Meeting...

Air Expo 2004

Mark Prokop led a discussion of ARFs. Practice contest flying with an ARF. Look for warps, fit, joints—add glue filets at weak joints. Check out covering quality. Beware of very light ARFs—they may not be strong. Examples discussed: Hanger 9 Cub, World Zero, Sig Rascal 110 (replaced weak hardware with Dubro).

John Green gave away a pile of aviation magazines. Thanks, John.
