Yes indeed, the Heron will be out after the Me-163B. Right now all attention is on the 163, so that can be released, and then it will be immediately back to the Heron to finish that project (which itself is not very far from completion - touch wood!).
We had some good discussions about what aircraft to do next, in terms of our personal interests, sufficiently challenging flight characteristics with enough available data to be rendered with precision and accuracy, amount of 'character' and history, and came up with the Dominie, Bulldog and Chieftain as aircraft we think are very much worth doing. The data and manuals for the Domine have already been obtained, and the RAF Museum at Cosford has been very helpful as well. Information and Manuals for the Bulldog have been ordered and should arrive shortly. The plan is that these aircraft will be built first, and then the Chieftain. A lot to do, but, as always, an enjoyable creative and learning process, and updates will be published as things move along.
