Very very nice and I was quite intrigued until I got to the part where they have a "sound system to replicate a Merlin starting and stopping" (presumably, only in the pilots headphones) and a "smoke machine to generate white smoke on starting through the right and left hand dummy exhaust stacks"
Now we've all sat in cars and made brmmm brmmm noises but never ever in public, and this...
I was at a large scale model aircraft event last year and one outstanding ver scale Mosquito had an onbourd sound system replicating start up, idling and variable speed twin Merlin engines.
In flight, scale speed and a still day you were completely fooled.
FANTASTIC.
