Just this last week end a new member of my club just showed up at the feild with one of these Cubs.. When it did fly it flew very well but the 27 MHz radio system seemed to be taking a lot of hits or he was having problems with his receiver/electronic speed control. I don't care for it after seeing one fly. I put together the great planes 3 channel Cub for my 13 year old daughter with a Park 370 brushless and a 1320 milliamp 3 cell li-po and it flies wonderfully for at least 10 minutes.

The plane was lethargic and under powered with the stock gear but it was flyable with about 4 min flight times.
