RE: Enlarged Zirioli Turbinator 125% size
Question were the rear wing bolts through the wing is is a balsa block or pywood block in the wing? Reason I ask is on the ARF I had to drill out all 4 mounting holes and remove a fiberglass sleeve that was in each balsa block to get enough wiggle room for the bolts to align and thread down to the blind nuts in the fuselage. There is 2 plywood plates used with large washers on the bolts to secure the wing and not pull through. Should I make 4 new fiberglass sleeves to reinsert? I assume its more to keep the holes from elongating? Don't want to loose a wing over something like this.
