Sent from my XT1585 using Tapatalk Neither, Experimental for research and development purposes. Shouldn't be a problem either since I doubt an F model could possibly hold enough fuel to allow those 36 cylinders to come up to full power long enough to get airborne. 1
Hank Posted February 25, 2017 Report Posted February 25, 2017 I think you're trying to make Clarence jealous . . . . All of those cylinders, all of that fine plating . . . . . 2
Guitarmaster Posted February 25, 2017 Author Report Posted February 25, 2017 Nine banks of four cylinders each. Never saw service on an airframe as turbines eclipsed it. Now its just 36 cylinders of pure awesomeness!Sent from my XT1585 using Tapatalk 2

rbridges Posted February 25, 2017 Report Posted February 25, 2017 How long will your 52 gallon tanks run it?

Guitarmaster Posted February 25, 2017 Author Report Posted February 25, 2017 How long will your 52 gallon tanks run it? 64 gallons thank you very much! Sent from my XT1585 using Tapatalk
RLCarter Posted February 25, 2017 Report Posted February 25, 2017 64 gal should get you around the patch once........ 1

DAVIDWH Posted February 25, 2017 Report Posted February 25, 2017 Hate to pour cold water on a hot topic, that being said, you may need a bit of aft ballast to solve those pesky cg issues. With the io550 in the m20R, Mooney partially solved the forward cg issue by adding another battery aft. Suspect in your case you might consider this method of solving your forward cg problems. Additionally, if you need a bit more thrust on takeoff, the Scimitar prop will help immensely. 1
Guest Posted February 25, 2017 Report Posted February 25, 2017 As with all mods, they tend to snowball. As well as a new prop, and battery relocation, you'll need to install a larger nose wheel, an a new larger wheel well, and so on. Clarence
aviatoreb Posted February 26, 2017 Report Posted February 26, 2017 I know... i figure if you extend the tail back about 75 ft and then put a few batteries back there and the Cg problem will be fixed. then make a tail dragged conversion and really long main gear to lift the nose up so you can put a real big prop on the nose. there - problem solved. Now what's for lunch? 1

Sent from my XT1585 using Tapatalk I think that you'll need two of them, the engine appears to have two concentric prop shafts, which is good news as you won't need to install rudder trim. Clarence

The best way to cure your cg problem is install the skymaster mod to your Mooney and put a reversed engine in the back:)Sent from my iPhone using Tapatalk 1
mike28w Posted February 26, 2017 Report Posted February 26, 2017 Changing out one Lycoming for another......shouldn't be a problem . 1
1964-M20E Posted February 27, 2017 Report Posted February 27, 2017 well you can always take off verticaly to 30k feet (64 gallons of fuel) jettison the engine and glide to your destination. 2
