Agreed, I had flown nothing but bipe for a number of years and found some a lot better then others. A lot depends on set up too. The best all around Bipe I ever had was my 66 inch Tiger Moth, it was as close as a trainer as I have ever gotten but it would still stunt when needed. I have flown several giant scale Ultimate ARFs for people, several I had assembled and set up for them. Some were just better then others but the Ultimate is a full on stunt plane and can get away from someone new to flying or just returning to the hobby.Most 3-D planes are easy to fly if you move the CG forward and cut down on the control throws and soften them up a bit. I love Bipes but hate assembling them. I could get my Moth and Boeing into my van assembled but it took a while to figure out how. I took both of them with me to most IMAA events fully assembled.
