I have flown my Playmate several hundred feet away and had not problem. I did have a problem with the esc at about 3 months and many flights. I sent an e-mail describing the problem and the company sent me a new board and it corrected the problem. I love flying that little plane.
The esc would cut off and I would have to bring the throttle to off and them bring it back up to get it to work again. I was flying outdoors and just flew it high enough to shut the throttle off and back on to start the motor, but when I started to fly in a gym, I couldn't fly high enough all the time so I replaced the board with the new board and it has been great since.
I have had the Playmate for about a year or more.
Good luck de Durwood
