Hello Bob,
I tell everyone that if a person could train on a H-9 Ultimate Biplane they'd be flying by themselves in no time......I truly believe that it's one of the easiest, most forgiving planes I've ever flown.
It's big, so it's not squirrely like a lot of the 40-60 size planes I see folks trying to learn on, but giving up after one to many meetings with the ground
It goes where your inputs tell it to go......nuff said.
It can be setup for very mild performance or rock-star all out aerobatics.
Will it compete with the ultra-3D planes out there....no, but then again I enjoy flying mine like a real airplane anyway
Bill
