I know how that feels. I am slowly learning Ka-50, F-5E, Mirage 2k and Su-25. The Kamov is being especially hellish with its profoundly weird fly by wire system. This afternoon, parts of it wouldnt even turn on! but the thing did trim strangely enough. I could fly, but not hover. And then it refused to fire. Frustrating bugger. But fun when it works. In the distant future I can see the joy being actually tactical in that thing is gonna bring.
Some people love climbing cliff faces. I like to climb learning curves. Mixing them up just increases the challenge.
