I am building a tail dragger RV7, and was wondering if the holes in the centre spar where the rear wheels attach if building a tricycle undercarriage version are left without bolts or if these holes need bolts installed?
The bolts that hold the main gear weldments to the center spar on a trike are also the bolts that hold on the wings. Are those the bolts you're talking about?
Perhaps I am wrong about the gear attaching here, as the holes I am talking about are actually between the rivets in the top part of the spar so there is no way that the wing would slide past these?
