Wasn't it an Atkins engine that had internal problems recently and was rebuilt by them at no cost? The design of the injector rail they supply (with only two injectors) worries me a lot. With four injectors Paul Conner's last flight might not have been. This has nothing to do with their redrive, but it does make me wonder about the engineering there. Since you're "playing off" me, :) try to follow what I did as closely as you can. Just miss out the bad bits :) The RD1B from RWS would be my recommendation. John Slade RD1A upgraded to RD1B after 50 hours. No signs of wear on the parts.
