I had one too. A great performer, very F3A-looking hence great flying. As mentioned the elevator setup needs to be changed to dual servos and the retracts sold by ESM are junk, so go for something else. I setup mine with a fairly low power motor and it did well, a friend shuffed in a motor that puts out about the same power as the Wren. Still did well.
