I recently joined the PRA and feel very honored to join. Much thanks to John Rountree for all his help. I am a returning to aviation after 43 years. I got my privates license when I was 18 and life happened. I am currently taking some flying lessons in a 172; but all things considered I will remain a sport pilot. My question is two fold. First, what are you recommendations regarding a ground scool course? Second, which models can be flown with that rating and which model has the biggest useable payload. Thank you. Gary Frick
