BJR 93TZ - I like your thinking . I have read some of your posts through the years. I have been in this hobby since 1975 and F3A since about 1980 of and on. Yes F3A is going towards the indoor and 3D trend. I say dear FAI members. Stick to F3A. Smooth and graceful. Like watching the Blue Angels, Thunderbirds. If you wanna fly 3D go to IMAC and indoors. And yes long live YS!! Thank you for those machines Mr. Yamada-san. I met him in 2009 at the Portugal F3A worlds.
