Narrative:

After purchasing a lancair 360; I took off on an IFR flight plan. On the takeoff roll; when passing 80 KTS; both adjustable rudder pedals suddenly came out of their detent. I nearly ran off the runway; but managed to get airborne. It was safer to fly than to stop with no rudder control and essentially no brakes. While being vectored and told to climb to 6;000 ft; I overshot my altitude and was very sloppy in maintaining a course because I had control problems and was experiencing moderate turbulence. As I climbed to 11;000 ft; I gradually got this under control and proceeded to ZZZ. There I effected repairs to rudder adjustment mechanism. My apparent ineptitude on climbout was a combination of control problems and turbulence.
