Made a decision, because I'm not able to get a bottle of catalyst for sometime apparently, I'm going to use the parts I had made for the other projects on this one without making a copy of them. I'll start afresh on those other projects later as I know how to do it.
Anyway, here's a couple of pics of the previously made parts which I hope doesn't contravene the rules. This will be the Napier Sabre VIII which was tested with a contra-prop according to the noted aviation author, Phil Butler. He told me he had seen a photo of it when he was researching other stuff at Kew.
The idea here is this MB6 Long Ranger was more a interdictor than a night fighter. When I first looked at the kit my thoughts were it has to haul a lot more weight around, what with the two crew and all the radar gear and extra fuel tanks so needed a much more powerful engine. And seeing as the MB5 was a development of the MB3 which was powered by a Napier Sabre, it seemed to me an obvious choice to make this one Sabre powered. I've read that the Sabre VII and VIII were 3000+hp engines and that Napier had bench tested some Sabre VII's to 5500hp, so I'm thinking a production variant could have been around 4000hp. So that's what I'm going with here.
This is what I have made so far a few years ago, the new engine nacelle. It was intended for the Hawker Fury prototype LA610. There's photos on the internet showing the real one flying with the Sabre VII. I also started on a contra-prop with two 4-blade propellers, I figure if the Wyvern got the same with an engine of about the same power, that's what I'll go with for this one. I have to finish the contra-prop as I had only trial fitted the parts to see if the idea on making would work.
