Thanks and sorry for being blind (again). The "quickbuilder" installed the bellcrank at BH 8, 1/4" off (placed relative to the BH horizontal flange versus the vertical section). Also, the hole in the deck between 11 and 12 is too small so I can't get full range of motion until that's changed. Should be able to make it work without moving the bellcrank/autopilot servo brackets. The middle elevator bellcrank might be off by a couple of degrees after modifying the push tubes to fit. Force wise, nothing will be noticeable; no more than 3% change in forces required. Also trying to leave enough rod end adjustment if I wish to change the elevator control sensitivity. Guess we'll see.
The middle bellcrank/bulkhead "contact" point would actually seem to be a better place for the elevator down limit. The geometry doesn't provide the mechanical (dis)advantage that the elevator BC hitting against #11 would; also steel against aluminum there. That said, I'll probably stick to the plan.
Thanks again.
