Does anybody know the torque needed to tighten the main and rear spar
bolts? going over the manual I am unable to find a specific direction. I
spoke with the factory regarding this and their answer was very vague. I
suggested 60 lbs/inch for the front and was told to perhaps begin with
50 lbs/inch and then see. Since both front and rear spar bolts go thru
glass and phenolic, 43-13 guidelines do not apply here. Maybe somebody
in the group has figured the desired torque. Please advise
