    Engine torque effect.

    Is there away to add the engine torque from the rotary engines?

    I'm working on the Sopwith Camel's air and cfg and want to try to have it so it can snap turn using the engine torgue. This is for CFS2 so I do realize the limitations.

    Has anyone ever tried to do this?

    If anyone has any ideas let me know.

    Till Later,
    John

    My initial guess would be to increase the prop MoI, but I only work in FS9/FSX so dont know how CFS reacts.

    Dev One,

    Thank you I'll try adjusting it.

    here are the current specs.

    propeller_moi= 12.697

    FSedit suggests a value of 13

    I have increased it to 18 with some effect but not much. Now I know that it was the actually the throttle controls (or lack of) that would make it snap turn. didn't it want to roll one way when the mags were off and the other when turned on. Or something like that.

    how high should I go. I was thinking that 20-23 would give more of a result. I'll have to test it.

    Rami,

    Wouldn't an elephant have the same effect.

    BH, I only suggested upping the MoI because as you are aware the engine as well as the prop rotate, FSEdit would probably not realise this, so you might even have to raise it to 50! Just a guess.
    Not sure though how FS itself will react to switching mags on & Off although there is a curve in the .air file (table 509) that controls the speed of rundown & also I think in the .cfg file the min throttle limit can have an effect.
    Good luck - keep trying.

    BTW are you using FSX or FS9? & which model?

    I'm using CFS2. Its the Sopwith Camel from the Aerocrates. I'm just playing with it. more or less.

    I'm trying to get some of the Gyro effect from the engine torque. Mostly to see if I can.

    As far as the mags go, It would not work as intended. the engine would just shut off. Though maybe some thing in the throttle curve could be used. I don't know. I believe it was the sudden on and off of power that gave the Camel the ability to do the snap turn. I also think its why so many pilots died learning to fly it.

    Did all of the Sopwith ACs use the same controls for the engine? I'm going to have to read up on it more.

    Thank You Keith. I'll keep working on it and let you know what happens.

    I've not looked in great detail, but I have downloaded Classic Wings Camel, but its for FSX/P3D. Very interesting to fly. IIRC they have developed a switch to blip the engine, because as you know Gnome rotary's (& other rotary's) of those days were either flat out or not at all, & the art of flying them was to blip the cut out correctly & to counteract the resulting change of torque that ensued.
    I must try it again......Having changed computers I need to reload it.
