It's been a while but I finaly got around to putting the YS63 on my Protege Trainer. The first thing I noticed was the difference in wieght between the GMS76 and the YS63. The GMS made the plane nose heavy. The YS63 is light now and the plane finished almost neutral, but favored the tail heavy side. She climbs well and cruises well with the 13X6, and has decent vertical, but the dihedral conquers the climb. Most of the time with the 13X6 I was at 1/3rd throttle. This plane will be for aerial photos, not 3D, but it's nice to have the power. It's kinda like owning a Ford Taurus SHO, you know you'll not use that power all the time.

After a tank of break in with a 12X6 prop, I mounted a 13X6 and took it up for two tanks. The last prop of the day was a 14X8. This was too much prop for the 63. So maybe a 14X4, or 13X8 would be better. I do not have a tacometer yet but I have a temp gun. With the 13X6 Iwas at 208deg., with the 14X8 I was at 196deg. I dont have it perfect yet but next week it will be just fine.

Here is a pic.
