I've got my CPD4 copilot installed and working on
my MX400 Pro. (non ccpm)

You gotta see it to believe it. It hovers the heli
in a very stable hover when you center the right
stick. I'm amazed...

It won't fly the heli for you....just hover it. But
that's enough to save you from crashing when
you get disoreintated.

BUT, you can't use it in the driveway or backyard.
It's sensor's see everything for miles and it will
try to move away from anything close to it.

But since I fly in a huge park with no trees it works
great for me.

Highly reccomended...
