When Scott had said to Dean that the Opal was ready for him to fly Dean took this to mean it was ready for anyone to fly because it was always intended that the Opal would go into production. At the time of the Opal accident Scott had been trying to set up a 200 aircraft deal for coastal surveillance, and it was always going to be sold as an ultralight as a follow up to the Sapphire.
The reason for the delay in anyone else flying the Opal was that it was very stable in 2 axis but Scott could not get the pitch right. There was either too much or too little response to stick input. Scott spent a lot of time trying pushrod adjustments and different bellcranks on the mixer system.
Before flying down from Bellina Scott had fitted a trim assist device to the elevons and said that it now flew 'hands off.' The Opal had always flown well but Scott was not willing to let anyone else fly it until the pitch input problem had been solved.
There was another Opal under construction at the time of the accident. The Wing Mould had been made and there where drawings but Dean does not know what has happened to them.
Scott had four aircraft planned or completed at the time of his death. The Facet Sapphire was the first, and the Facet Opal was the second. In the early planning stages, including a radio control flying model completed and flying, was the Facet Diamond.
The Facet Diamond was to be a small 300 knots flying wing powered by a small turbine engine. The fourth, the Facet Gem was an idea that Scott had but had not formalized.
