Hello,
as i start to the conversion of the original trottle – i created a separate Page to cover all the necessary informations. To see some documentation please click on the related page above: updated 17.09.2013 – added description for Trim indicator mechanics and motor block for Lever movement.
I Have had a quick question
I have modified a 737-500 throttle to use a 3 turn potentiometer and a chain and clutch to actuate
I use Opencockpits SIOC USB dcmoto plus Iocard ，I don’t want to use the opencockits throttle program，But the program never completed successfully,prosim737 settings are not friendly.
Is there any script for USB DCmoto plus that I can refer to?
The following is my reference to the opencockits throttle script. After prosim is set, the trim wheel and speed brake have no action.
