Suggestions.

They way the game modes currently work I think could use some improvement among other things. Take a look at War Thunder, a computer game. Realistic mode should be a proper sim, Hard should be a realistic mode but with all the factors ( deceleration, acceleration, turn rate, etc.) for realistic flight not turned on all the way, or tweaked to make things slightly easier and keep the HUD and target indicators. Also, the rate of deceleration and fuel consumption is a little too fast for all aircraft. I lose too much speed to be normal in a turn in the phantom and I can barely make it to LZ alpha from Nakhon in a fully fuelled helo.
