I have a Funtana (Saito 91 with 4 x 14 prop) and a Extreme 330 (os61fx with a 12.25 x 3.75 prop). The problem is these things fly so slow with these low pitch props and then just stall at the last second on approach, usually wrecking the landing gear. I'm trying a little more throttle (obviously) on final but still struggling some. Any tips?
