A wonderful subject, and the model still does the rounds at Calshot. Trevor Hewson (who took the photo) made the first one and I went halves with him over the plan. His was all-yellow, mine was the camouflaged one - I do enjoy painting and decorating!. His is slightly lighter. We have flown them together at the occasional indoor meet. Power is the ubiquitous GWS IPS and it spans 30"
