Couple of problems here:

when in Su-25 familiarization mode, the msg reads to hit ECS key to take control...either that is mispelled ESC key, which doesn't work as it just throws me back to the mission screen, or I don't know what the ECS key is...



Also I can't start the engines. Cockpit looks nice, though.

Found a nice site for that kind of questions, asuming that your talking about the Su-25T from dcs world.

Right Shift L starts the electrical system.
then
Right Ctrl key to start up your engine. your throttle needs to be near zero to start it up.

if that doesn't work check your keybindings.

goodluck.

Damn i can't seem to edit mine own post, stupid work pc's.

it's Right CTRl Home to start your engine ;-)

I think the Su-25 training "tracks" are actually just movies - the "hit ESC to take control" is a left-over from when they used to be tracks in LockOn.

Starting engines is rightAlt+Home and rightCtrl+Home...I think...

thank you!
