I have AFPD and G4.5, both work very well for pattern practice, but I preffer the AFPD, I have not being able to make the Osmose to fly well, I have the Osmose Evo and had the original, and the models flies horrible on AFPD, so I fly an extra or the smaragd. On the other hand the G4.5 flying the Pinnacle has being great, but is not the best for the P or F11.
