Cut a tab off the aft upper cross tube of the control triangle. This was running into the seat bottom at aft stick positions. Checking the plans, this tab is not shown, so maybe it's for the Waiex version. Filed it smooth, and primed and painted the cutoff area.
Raised the seat by 1/2". Drilled out the rivets for the lower and seatback hinges. Moved the one for the seat bottom down by 1/2". Measured a 1/2" wide strip at the top of the seatback, cut that off. Drilled and riveted both hinges. Now the seat bottom hangs well clear of the control triangle and the elevator idler pushrod.
