Thank you so much Peter.
As for the throttle actuators, in the other thread, there is a link to the M5board (http://www.m5board.com/vbulletin/e60...-actuator.html
) where the throttle actuator were taken apart and it looks like the plastic gears were wearing out prematurely. Would be great if you can come up with something also. I am hunting around at R/C gears but doubtful they will work.
