RE: My Homelite conversion, question about weight also...
Not sure yet, no servos! The elevator servo goes all the way back in the tail, which will help keep it back some. I thought about cutting out for the rudder servo too, and moving it in the back. I'll see how it works out with the pull-pull cables first though.
I wonder if the weight of that Fuji includes a prop too? I'm not very far off their weight if you figure the prop and mount too.
