Hi Guys
Which method is more durable for big stunters?
Installing the bellcrank rod in line with the vertical lite-ply spar so that the vertical lite-ply spar can also help in absorbing some of the flight and pull test stresses)
or
installing the bellcrank rod just behind the vertical lite-ply spar.
Of course, 2 plywood plates - one on top and one on the bottom will also be fitted between the fuselage sides and over the bellcrank rod to complete the bellcrank mount.
