Now that's a screen that would sell the GR9 , I don't have this one, got the Wilco GR, I really like the throttle quad control with the nozzles, is it the same with the this RAZBAM aircraft.
with this one it uses the propeller axis to control the nozzle positions, many people have an issue with this, but having an Saitek x-52 pro i have the controls set up all on my throttle ie my slider as nozzle position and a trim wheel for elevator trim.
Ok , sounds a good option, the GR3 , with the Saitek throttle quad, It uses the propeller pitch for nozzle adjustment for trust vector as two level side by side... works brilliant , sound you achieved the same result
