Bill,
I think Charlie knows more about the particulars of Bobby Hughes' RV10 Renesis installation than I do, so I don't have much to add. I talked to Bobby a few weeks ago, and he may be thinking about replacing it with a 3-rotor sometime in the future. I think he was hoping for 220-250HP, but feels like it is closer to 200-210HP right now. He probably has one of the least crowded rotary installations that I have seen, due to the amount of space in the RV-10. Even adding a 3-rotor engine would probably not make it much more crowded.
Bobby is currently dealing with some tuning issues that are related to his electric constant speed prop in combination with the ECU. He flew the RV10 over to the RotorFest from Lockhart next to Mark Steitle in his Rotary-powered Lancair, and he had to tell Mark to slow down near the end. His cooling is really good, but I think the temperature of the oil coming out of the gearbox is a little high, so he didn't want to push it too hard. His is a very nice installation.
Scott,
Glad the pictures may be useful to you. I find that most of the guys doing an alternative installation either tend to not do a website, or do not take enough pictures. I think John Slade has an outstanding website for his Cozy rotary installation, but there's just not enough pictures of the things that I want to see. Hopefully, with all eight installations at one event, I was able to get enough different shots to be of use for anyone wondering about different ways to do things.
John,
Complexity is just a large number of simple things in tight quarters. Probably not much more complex than a lyco installation, just a few more hoses, and those funny "finned" things. The engine core is really compact.
Tracy.
