A trainer is designed to train a person,in that aspect it wants to stay in level flight and climb with more throttle,if a person will learn aerobics on a trainer I think they will be a lot better pilot in the future,most people get away from the trainer and jump to a more aerobatic plane because its easier to turn or loop with,where as if they had learned with the trainer the flying would be a lot better,with the trainer one must force it out of the level mode. When the trainer starts to get boring just add more throw and move the c/g to the tail a little at a time,the plane changes personality,and yes it will knife edge,roll,loop,hover,inverted,tailslide,hammerhead ,flat turn,and big ole sloppy snaps,and sloppy spins,over the years i've built over 60 planes and probably flown over 150 different planes,and this a.m. I'm finishing a lt 25 with fs 52 for a club trainer and float plane.There are times my extras and 540's along with the ultimate's set at home while I have fun with a trainer.
