Thanks for that Pete, I'll give that a go. I have printed endless pages of various "easy" instructions but it all seems like gobbledegook.
So far I have all four throttles working, but I have to wriggle the right lever to acheive the final movement of full throttle( moves all four forward a fraction) then when they are back at the detent position they will all go into reverse thrust( aft of the detent )if I wriggle the left lever.
By wriggle I mean moving it back and forward several times by about one inch.
Sounds clever, but I have no idea how I've acheived this or if I am nearly there!
I assume that thousands of you out there are flying normally with a full throttle range and a simple pull back aft of the detent to acheive reverse thrust ! Perhaps a few could confirm this, especially if your using the Pro B707.
