RE: Goldberg Chipmunk with Saito 120 - advise
Sounds great. I originally has an O.S. 91 Surpass on this, and it just wasn't enough. Now I gotta figure out how to trim the rudder and elevators in the center so I can get more throw! If you hadd too much rudder or elevator throw, they run into each other.
I'm thinking about move my rudder servo to the back to help with the heavier engine, and possibly going to a different elevator linkage. The "Y" setup on the World version is a little weak....
