well ive been flying since only january. and i'm doing 3D with a Ucando46. I can hover, KE, flat spin. inv. FS, blender, harier. im working on harier rolls and rolling circles. and point rolls. these are very challenging to me. I have progressed really fast. but this is partly because i was flying a simulator for months b4 i got out to real world in january.i took off and landed my trainer the first day. and yes i have spent every posible moment on the field and every other posible moment on the sim. this spring i was at the field 5 days a week from 8:00 or 10:00 am till 3:00 PM, I haven't had quite that much time lately b/c of the bisth of my twins. and hospitol stays with them and my wife but the sim helped. plus i fly helis and that helps coordinate the rudder IMO.
so yes, at least 4h a day but not quite seven days a week. i cant wait to get my yak 54 up so i can start learning more precise flying than the UCD.

i still lack precision..
we dont really have a certificate program. but some clubs do. mostly we just try to recognize newbies b4 they get themselves into trouble or endanger anyone. i do think its a good idea to have certification pogram though.
