Hi Dale, if you re-read the post you'll see I was refering to the 150/180. My 150/150 is good for about 5 hrs to dry tanks at 130 mph, so I'm familiar with the animal. On the other hand the fuel burn goes up to that of an 0-360 (around 10 gph) at 140 mph...not really worth it at today's fuel prices and the endurance is about 1 hour less. My only complaint with the airplane is that it is an early conversion (done in 1969) and it does not have the gross weight increase. Like most 150/150 drivers I simply load it with whatever I need and fly it. Ideally a guy needs a CS prop with the larger engines but then you're talking about ANOTHER 30 pounds or so of payload gone. Years ago ACT configured their company 150 with 180 hp and a 3-blade CS prop. They said the performance was outstanding to say the least, but it was impractical so they never STC'd the combination. I'd love to have flown THAT airplane! Me...I'd like to hang a 220 hp Franklin on the nose and see how it works <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />
