I am aware of that. I started with IL-2 in november, after 4.09 was even released I think. But then I saw old posts talking about throttle support, and I misunderstood thinking it should have been in 4.09 but did not happen.
But either way, no idea when 4.10 will come, and if it will feature throttle support when it comes, and most likely it would not feature differential braking, radiator and fuel mixture.

There have been reports of malware warnings from the latest version of the throttle program. I assure you that it is malware and virus free. It is the behaviour of the program that is 'suspicious' for those anti-malware scanners, which are set to scan for any new unknown threat they don't recognize. So ignore any false alerts.
