I had good luck with Rossi's until about 1994 and then I switched to OS. Never went back to Rossi's except to try the 1.05's a couple years back in my MIG. I swapped them out after 6 flights and replaced them with OS's and was very satisfied with the OS performance. Stay with the OS's.
I have a Byron F-18 with twin K&B 82's which I am now converting to turbine. Here is the text from the actual Byron F-18 manual.

"CONTROL SURFACE THROWS:
Elevator 1 " up and 1 " down. Full travel with trim lever in full up position 11/4" up. Recommended up elevator as measured at the leading edge of the stab next to the fuselage to be 1" minimum. 11/4" up elevator is ideal for takeoff. Settings greater than this amount must be handled judiciously by the pilot during landing flare. Over rotation during flare can bring about a total end of forward movement and subsequent stall of aircraft.
Aileron throw to be 3/4" up and 3/4" down.
Rudder throw to be as much as you can get.

FLYING: This 18-19 lb. single engine ducted fan jet model is not a 150+ MPH aircraft. It has been built with one simple thought in mind: "A large stand-off scale model that is not only
fun to fly but also graceful and easy to handle". Take-off distances average approximately 250 feet from a hard surface runway (no wind). Stable in-flight characteristics make it a real joy to handle. F-18 drivers will be able to duplicate many exciting maneuvers such as slow flight, rolls, loops, knife edge and combinations thereof. Landings are highly predictable, set up the approach (power back, nose up), as the Hornet starts to settle, add power to maintain a steady rate of descent to the numbers. The F-18 (when handled correctly), will land nose high at a slow air speed every time. I would caution F-18 pilots against sudden and abrupt use of full up
elevator in the landing flare, as it is possible to completely stop the forward motion of the aircraft. Treat the controls as if they were a lady. GENTLY!"

Hope that helps.
