Maybe crackling is not the best description, there is a metallic sound that can be heard at lower thrust that I suppose resembles that when the sound-repeat speeds up. If possible to address, this would be my only wish to further increase the otherwise lovely feeling just cruising around and enjoying life in the sim 
Tried your suggestions for landing and I think I’m getting the hang of it with some more practice.
Such a nice plane in VR! Very sharp textures, great visibility and very nice fps!
