So which prop are you referring to? What does that prop do to your cruise speed!51598Rob wrote:Mine is a M5 210 with the long prop. The long prop will make your scenario work....but still, cut the trees!

I have the 82" McCauley. Don't know how it effected cruise speed, as I didn't fly it before the change from 76" prop was made. When I changed from 8.5tires to 31 inch tires cruise speed was significantly altered...10 to 15 mph! But cruise speed was a fine trade off for the advantages of the 31" tires for me. Swinging the big prop gets me off the ground quicker, climb faster, and down at a steeper angle than the shorter prop with same engine. I don't know by how much, put the io360 is lighter than the big engines, and in my opinion, is a good balance for fuel economy and power in my M5.

Rob, Agfisher, Iceman, Delta, thanks for the feedback.
I may be missing it somewhere on the forum but it would be really helpful to us new folks to get a post going where current members could post real-world data...STOL distances, cruise TAS, fuel burn, etc...for their specific set-up....Maule type, engine, prop, tires. If everyone used a similar altitude like 7500 ft and gave data as TAS it would provide a real "apples to apples" comparison. It would probably be pretty neat for those of you who already own a Maule to compare your performance with others as well.

Justinotto, there are too many variables on individual's aircraft to accurately portray the differences.
Empty weight, gross weight, drag factors, pilot capability, rigging, new engine power v older engine power, airframe correctness, wing trim, flap and aileron trim etc.
Basically higher horsepower is faster and quicker off the ground.
Fuel used is directly related to horsepower used with a little difference between carb v injection. Drag is more prominent at faster speeds, thus higher horsepower does not produce straight line speed increase.
The shorter the wing, the less drag thus faster but not as much lift and higher stall speeds than longer wings.
Then theres the prop efficiency, there being many props available, the five different landing gear available each with different drag factors and weight factors. There are four different flap configurations and many flaps on Maules I see are not rigged for best efficiency.
Best way to choose is define the mission and the monies available for both purchase and operation.then choose the model that will fit those requirements.
There are about 44 variations of the Maule since 1963.
Prices from $15000 to $600000
