Started assembling wing fold and lock mechanism. The slotted holes on handle are important and need to be done correctly or you may have some trouble getting the maiin spar pin to engage properly. I had to remove the handle a couple of times to remove a little more material from the top of the lower slotted hole. The distance from the pivot point on top of the handle to the top of the lower slotted hole shortens up when engaging and will put the pin in a bind before it engages fully.
Did not remove vertical part of spar for the notch.
Right wing lock assembly
Need the elongated holes in handle so main spar pins and rear spar pin con move freely
