Thank you all for your support so far. It's fantastic to see how quickly we are approaching the half-way mark.

Some people have asked whether the engine rotates and I'm delighted to say "it does!"  The original concept involved a hand crank at the back of the engine (as show in pic #1 below) but since then a clever colleague has added an electric motor for added oomph!

The addition of transparent panels on the fan case also lets you look inside and see the power gearbox up close.

*As a reminder, this model is a simplified representation of our UltraFan engine, realised in commercially available Lego pieces, which is not to scale.*
