I’ve never rebuilt an aircraft that someone else built other than my Speeda that had only a few things started. Enough stuff was done that it did take extra time to fix but FK SBA Speeda kits are in short supply so I’m not complaining!!!! You look some of the things that were done and it makes you wonder what they were thinking? In your case, what in the world are the round cutouts for where the servos were located? Hard to believe they were actually thinking about folding back retracts.
