I just got my Giant scale plane Yak 54. It looks like it is made well but there are several changes that need to be made to make it more user friendly. Just like the Katana I am going to trash the springs and use nylon 1/4 20 bolts to snug the wings together. I am also going to possibly use separate elevator servos with matchboxes to avoid the Y type of elevator push rods. If anyone else has any suggestions please let me know. I will be using an OS 1.60 two stroke for power. Thanks, Skip
