RE: 1/5 Pepsi Chipmunk - Build
James,
Went to the link provided and I hope to follow it. Are you the "cookie monster"? I tried to email photos to you but you need to be a member and the moderator won't allow any new members per the message I received. With the 40cc motor I made some adjustments for the cg. I don't remember what the plans cg is but mine is 123mm and that seemed about right. Keep in mind that I only have two flights on the plane as I had a dead stick on the second flight with the new eng.
I set up the rudder with pull-pull and the servo is inside the fuse, behind the wing saddle. I didn't like the rudder servo mounted at the tailwheel. This looks cleaner to me. If you send me your email I'll send you photos of the rudder servo set up I used. RCU's photos are not working at this time. Rick
