The span is 60'' and the wing area is 693 squares. We used JR 811's on everything with a r-770 reciever. RC-Pilot it has more than unlimeted vertical and is very good at 3d we will be shooting a video shortly and it will be on our site soon after that.As far as imac goes it is very good at that also its not going to beat a bigger airplane in the higher classes but it will do very well in basic.
