There may be different types of commissions - ones that the product is delivered and done, and others that are expected to improve over time. A good example of one that has received an incredible amount of updates is the Grumman Albatross HU-16/G111. That developer is excellent. He communicates very frequently and adds requested features and gives us previews too.
I’m glad an update to the YS-11 is in the works and hope it will keep getting updates. I wish I could say the same thing about the B707. 
For anyone in the SU 4 Beta, is the sequence of starting the engines fixed? From one of the real life videos I saw, the fuel is added (Condition lever to ON) after the starter is pressed.
