I'm going to advertise my Champ soon but figured I would put it out here first.
I have a 7AC-CONV Champ on PK1500 floats. This plane has been heavily modified and is LSA compliant.
Powered by a Lyc. O235-C2C, droop tips, 39 gallons fuel capacity, VG's, Whelen Stobes and NAV lights, starter and battery but NO charging system. Fish pole tube, plexiglass seaplane door, squared off rear windows with one opening for easy access to the baggage. Plane has PK1500 floats and wheel gear sold with the plane. $43K or DECENT offer.
