RE: WACO YMF
Van,
I know of 3 Waco's and a Travelair under restoration by museum personnel. There are more aircraft on the field that are being restored by individuals.
The SIG ARE ARF is actually the same scale as the smaller Pica kit/plans, 1/6th. AMA has plans for a 52" SRE by H.Osborn. you would need to have them enlarged or the 70" ARE by D.Brisghella reduced to about 59-1/2" for a 1/7th scale plane.
Ken, I've got the folding rulers, dont need to bring one. Thanks Jay for the tip.
