Am I correct in presuming that formed prop blades were common in the earliest days of indoor free flight (both duration & scale), when ever that was? Were they also used in outdoor free flight, too or is that relatively new? When did laminated blades first appear?

For indoor duration, I believe plans from the 1930s and earlier would indicate carved props more popular than formed props. Gary, you are probably just the right person to research and write this histoty. You could prolly piece together much just from Zaic Yearbooks. Also contact David Erbach for ideas. His indoor history (duration only) should be still linked in the Links section to left of message board.
