I voted for "Made In Britain" GB with Contrail Mayo Composite in mind, but knowing my pace and determination I'm not sure that I could complete the whole stack in time so I decided to do one step at time and start with Mercury.
Contrail's Mayo Composite kit was a joint effort between Contrail and Airframe each providing one aircraft.
Airframe S.20 moulds look very basic but buildable, will require a lot of scratch building, scribing and detailing to look right.
