RE: GP Ryan STA
Ed,
The Robart struts go through the wheel pants just by turning them the right way. The Robart instructions detailed this.
There's not a lot of room to spare for wheel clearance using the Robart struts. I tried several brands of wheels and they were all too wide, dragging on the struts. I ended up using the stock wheels, and even needed to sand the corners down a little.
My Ryan is flying as an electric and has excellent performance.
