bigtim, the Conquest is an older four channel system. I'm looking at costs of receivers for when the plane is equipped with floats just in case the receiver gets soaked beyond repair. The receiver that would work with the 9C is around $100 while the receiver for the Conquest is around $40. This plane will not be equipped with floats without having a full house control system in it. But going back to the original post, I was asking opinions on which would be better, going to one instructor with a full house plane with a modified flat wing or going to another instructor who refuses to teach on anything that isn't 3 channels with lots of dihedral.
