Greetings,
I am going to be building my Dragon Lady 60-90 real soon. I wanted to get some of your tips/mods before I started.
I will be powering it with a 4-stroke 1.20. I have yet to decide between Saito or OS.

Thanks for your help

Hey HydroLock good choice I am currently flying a lady with a saito 150, and it has power to spare. I used standard servo's in the fuse "lot's of room" and no extra nose weight was needed. The axles provided are a little cheesy and the wheels were kinda flimsey but most everything else was good, even the 16 oz. fuel tank was OK. If you invert Saito it will idle fine iwith an O.S. "F" type plug. You may find that the cowling is a little close to the edge of the fuse for mounting, 120's and 150's are long, but some mounting blocks epoxied to the fire wall will solve that. the FA120 and FA150 are almost identical in size so you will only need a minor whole in the bottom of the cowl and a small whole for the needle valve. I have moderate aileron and elevator travel but maximum rudder. Kinfe edges are easy that way... This model is an aerobatic champ and lands like a lady. Just make sure your low end idle is set well for landings this model flies well but doesn't want to come down. The fat airfoil provides lots of lift which allows slow landings. Good luck I'm sure you will enjoy. I'll have some post soon I'm putting together a GP Super Stearman with a Saito FA-180 " MMMM Horse Power"
