That Zenoah is pretty cool in the SS. I have a OS 91 FS in mine and it is perfect for this plane. (graupner 14-7 prop) I just finished putting a AR7000 rx in her and "tightening up" the covering after the first winter storage. I hope to get out later this week to put the first flight of the year on it. (If i can put my helis down long enough, LOL darn things are too much fun)
To all you new skybolt owners, enjoy your new skybolts becuase they are a fun, relaxing, good lookin, just plain 'ol sweet flyin plane.
