Re: Call to gp pitts special owners!
Use the hardware as it comes. Be aware of the top wing/cabane attach brackets. If they are shiny or chrome looking, replace them. They get stress cracks in as little as 3 flights. Also make sure that the hole that is in the bottom of the center section of the top wing is marked with a tag. Early versions need a modification INSIDE the wing center section. (You had to cut open the wing sheeting and add a piece of 1/4" ply for the screw to hold the brackets to.) Without the modification the screw would go into the spruce spar and since it was only 1/4" inch square, you had a pretty decent chance of missing solid wood. This would in turn cause top wing failure. I'm not sure you've ever had the displeasure of shedding your top wing on a Pitts but I'll tell you the stall speed of what's left flying just went WAY up!!
Stay in touch and when you get yours I'll feed you whatever info I can.
