With the motors and propellers still at the workshop nearest the flying field where the previous prototype was test-flown, I mock up their appearance for the benefit of a PR shot at the studio in Liverpool. Tins of tuna sub for motors and it matters not whether in spring water or oil. Propellers are fashioned from flooring laminate, twisted with a heat-gun before being stuck to the tins with bathroom silicone.
If you don't intend flying your prototype, these make for a cheap and tasty alternative.
