This kit builds "heavy" so I drilled lots of holes trying to lighten it but it still came in around seven lbs. I haven't flown this one yet but my first one was lots of fun. There is a build thread somewhere on the net, try Googling "Goldberg Chipmunk".
I think the pull-pull rudder is a good idea I should have done it because the rod I'm using is long and it looks like it is going to bend with any air "load" on the rudder.
Post some photos when you get going.
