Good to see another flier remembering everybody's hero - Carl Goldberg. Over the decades I've built many of his planes, still have these flying:
C/L - Lil Satan, Lil Toot, Cosmic Wind
RC - Eaglet 50, Sr. Falcon, Gentle Lady, Eagle II, Skylark, 25th Anniv Cub
Great planes from a great man. Can't say more than that.
