bigboy3178 Posted December 25, 2008 Share Posted December 25, 2008 anyone have any useful info on this engine, especially anyone whos actually flown one? Just wonderin maybe how it stacks up to the IO-540 in general? thanks!! Quote Link to comment Share on other sites More sharing options...
Edge 513 Posted December 25, 2008 Share Posted December 25, 2008 What do you mean by useful info.? Useful to what? Each iteration in Lycomings line up with 360 size juggs adds 2 more cylinders in parallel. 360/4..540/6..72/8.... each adds about 100 pounds. Is there something canardwise you are planning on building that could fly with that much steel in its arse? Quote Self confessed Wingnut. Now think about it...wouldn't you rather LIVE your life, rather than watch someone else's, on Reality T.V.? Get up off that couch!!! =) Progress; Fuselage on all three, with outside and inside nearly complete. 8 inch extended nose. FHC done. Canard finished. ERacer wings done with blended winglets. IO540 starting rebuild. Mounting Spar. Starting strake ribs. Link to comment Share on other sites More sharing options...
bigboy3178 Posted December 25, 2008 Author Share Posted December 25, 2008 just a curiosity about the engine really, i hadn't anything really in mind. Quote Link to comment Share on other sites More sharing options...
Terry Posted December 25, 2008 Share Posted December 25, 2008 IO720 = 720 cubic inches, 400 horsepower, 8 cylinders, about 600 pounds, twice as long as an IO360, ueses twice as much fuel as an IO360. Check the TCDS on faa.gov for more details Quote Link to comment Share on other sites More sharing options...
flybeech21 Posted December 25, 2008 Share Posted December 25, 2008 I have about 100 hours in a Queen Air with the Excalibur conversion which is putting 720's on instead of the stock geared engines. Operating the 720 was no different than the 360 or 540. But, it sure does sound awesome! The owner of the airplane was demanding about babying the engines. He said that the engines and parts were not that easy to come by. Cant say that I can verify that because he handled everything with the airplane except flying it.

bigboy3178 Posted December 26, 2008 Author Share Posted December 26, 2008 wonder if then a 540 would be just as good a buy, since the 720's only advantage seems to be only a modest increase in horsepower. Quote Link to comment Share on other sites More sharing options...
flybeech21 Posted December 26, 2008 Share Posted December 26, 2008 I would avoid the 720 and go with a 540. There is not going to be a parts availability issue on the 540 in our lifetimes. Kevin Quote Link to comment Share on other sites More sharing options...
Edge 513 Posted December 26, 2008 Share Posted December 26, 2008 I still dont understand this train of questions. If you need a 720's characteristics you need a 720. How can a 540 be an option? "...540 just as good a buy"??? what does that mean? Quote Self confessed Wingnut. Now think about it...wouldn't you rather LIVE your life, rather than watch someone else's, on Reality T.V.?
