What is the BIGGEST motor for Kadet Senior?
I flew my Senior Kadet with an HP VT.49 four-stroke. It took a little longer to get off the ground than I liked, but it was probably about normal.
I have flown Senior Kadets with a Saito .91 and a K&B .65. None was really over powered, but all were throttled back considerably once airborne, even mine with the HP four-stroke.
