After about an 8 year build it finally became an airplane. I have 10 hours on it so far and am going through a very structured test flight program. I am just starting the aerobatic portion.
Some info about it: My own design airplane based on all I have learned over the years messing with aerobatic airplanes. Not a Cole and not a Swick. Wings are 11' panels with wood ribs, ply leading edges and 9' ailerons with spades. Fuselage did start life as a 1946 BC12-D but only about 1/2 of it is original. Landing gear, engine mount, doors, cowling, boot bowl, tail brace design, and control system are all based on my design and are scratch built. The engine is a modified IO-320 that is putting out around 180 HP. WOT I am seeing 155-158 MPH at 2900 RPM. Cruise seems to be 133 at 2500 RPM. Prop is a Catto 76x52 (I think). The engine is still in break in period so I am being careful to keep temps and pressures exactly where they need to be. Stall is somewhere below 50mph power off and power on there is so much indication error it is hard to call. The nose is way up and it just sorta mushes. Super easy airplane to fly.
I'll add more photos and info as I get through the process. Was totally worth the grind.
