Im at 610' above sea level. We have 2 of these flying. I have a 210 Moki the other has a Saito 180. I like the Saito better. Throttle transition with the Saito would be hard to beat. The Saito plane is lighter, to offset balance we used One rudder servo vs. 2 with the Moki.. If I were you, use the Saito. It pulls out of a hover effortlessly..Sounds great also...walt
