RE: F-20 have washout?
I have a Direct connection f20. If you want to talk about speed, I have installed a YS 61 with pipe using an 11 x 11 apc prop, retracts and a shute. Man does this thing go. I estimate 140 - 150 mph.
This plane flies and tracks straight as an arrow but I have to land it as fast as you normally fly a sport plane. It is in in 6th season and still going strong. You have to be on the sticks at all times.
