Regarding the servos required for the F-100. My F-100 is rigged as per BVM servo list. The servos are more than adequate. Putting 8611s on the ailerons is like putting short block V8 on your lawn mower. It will cut the grass just fine but people will wonder why your mower can hover. Then you will spend countless hours trying to make them fit.
8611s on the stabs is fine you will have to mod the install. They will not fit in the servo tray with out taking out some plywood. The easiest way is to cut the top facing side of the servo tray, making a "U". Then elongate one end and they will slide right in. You will need a matchbox with the stabs they are mucher tighter than the 8411s. Don't need digitals on the rudder or flaps. I have rigged a couple F-100s since completing my own. I actually rigged one over the phone. It was like taking a retard to Disneyland but we got it done.
