Well it been a long time but I still have my FMA co-pilot installed in my MX-400 heli

and it still hovers hands off... Its an amazing thing to behold...

Of course people who have never owned one will claim it can't be done...how do they know that????

Go to FMA's web site and look around.... and remember, if you do buy one they hold thier resale

value better than almost any product...
