I started with a 50mm F-16 from BananaHobby. Great Plane. It was quite stable and went up to about 80mph wide open going nose slightly down. I have boughten a Airfield F-16 from nitroplanes.com. It has a 70mm edf.It is super stable (even at extra slow speeds!!!) . It is very easy to hand lunch. Takes off at about 35mph and goes about 80mph nose slightly down. Don't get the Thunderbird scheme because it is very hard to track for a first edf. The 50mm F-16 is very hard to keep track of in the clouds. The Air-Field F-16 almost hovers on landings.
