I got a lucky break and won an eBay auction for a NIB AirCore Knighthawk. Even though these kits are 10 years old I'm optimistic it'll be the reliable trainer I remember reading about years ago. After reading the building instructions the build-out looks easy enough; it's been a long time since I built control-line planes in Junior High. The under powered comments I've read are plentiful & I hope to overcome this obstacle with a new Saito 56. Wish me Luck!
