My point exactly, I'm no hotshot pilot.
I think a lot of folks who think the BCPP is twitchy and uncontrollable just don't have them set up correctly.

And as far as good trainers go, If I learn to fly on a BCPP and can hover it well, perform basic maneuvers, etc. the go to a TRex, I think I would be in good shape. If I did the same learning on a TRex, I might not be able to fly a BCPP well at all....
Just guessing, obviously I can't do that experiment. But I can stay in practice indoors with the BCPP while my MX400Pro/Trex hybrid gathers dust, waiting for good weather.
