RE: how tough are receivers?
Hey Steve.
The receivers themselves are pretty tough. However, the antenna that stick out is not. constant bending of the antenna could cause them to come loose, If you MUST move it often, Consider shrink tubing the antenna. I shrink tube all of it and only leave about a 1mm of it at the tip. Some people just shrink the part where it enters the receiver so it doesn't kink often.
As far as for your easy glider, 6200 is not needed. You'll be fine with a 6100 park flyer.
