    Hi Guys, In your opinion what is the ideal RPM of a motor at the final output. For a
    a) Flight Simulator
    b) F1 Simulator

    I read many posts here where members suggested 180 to 200 RPM. Then I saw a finished 6DoF with 50:1 gearbox output of 19RPM.

    Probably 19RPM is too slow for a race rig. Nevertheless the speed of the turns depends how long the lever would be in addiction to the turns. My winches turns 23RMP and the lever is 16cm (!) long. The shorter the lever the faster the motor. The shorter the lever the less forces needed, the less move is expected.

    the longer the lever the faster the motion actually, but yes, it can reduce torque.
    I use 40mm CTC levers on my big worm gear motors and it translates to about 300mm per second travel.
    However, @eaorobbie uses the same motors as me but 65mm CTC and gets about 500mm per second travel.
    We find that with the graph in JRK utility. We send the motor from min to max and see how fast it moves in the graph.
    The generic speed recommended for race is minimum 150mm per second travel. That gives reasonable speed and sharp motion for race. Anything faster is a bonus.
    For flight, you can use slower for sure.
    If however, you have motors that move fast for race, they are fine as they will move slower for flight. But using slow motors for flight and then for race is not recommended.

    Thanku BFST PIT for your response, I took BSFT advice from another post while ago purchased 2 motors with 200-225 rpm output.
    Anyway i feel a first timer should start with a 50 - 100 rpm for a flight and 100 - 150 rpm for a race

    faster motors should be considered if you ever think of playing a race game on a flight sim. Its easier to slow a motor than to try to speed it up
