The way the FMA co-pilot works is like...magic. That's
how I felt about it the first time I flew with it..

That being said, they are very, very easy to set up
IF you follow the instructions to the letter. They come
with a very good manual that shows each step with
photo's.

NO, I would not try to fly the co-pilot heli in the house
unless you turn OFF the co-pilot. It would "see" every
thing in the room and try to avoid it and go berserk.

I turn mine off in the house...

If you see a good deal on a Heli-Max MX400 Pro you
might consider getting one. It works with the cheaper
CPD4 co-pilot because it is Mccpm and not Eccpm like
the Blade Cp.

Anyhow...Happy Hoving..
