Thanks for the respnse All, I'm used to the old stuff and the size alone he rec. causes concern. I'm sure modern tech is better, but I just want the extra input. I have put 5 AR500's in semi trainers and gliders, AR6200 that came in my P-51 PTS and have decided to give the AR7000 a shot in my new (to me) Ricochet 2m plane with YS140S. I just wondered why the need for the rec. that took the additional remote ant. Is this overkill or justifiable for an all out competitive pattern plane.
