Just browsing their website and noticing that useful load ranges from 800-895 lbs on a modern, 4-5 seat plane with 230-260 hp engines and 85 gallon fuel tanks.

Their MT-7-260 model has 300 lbs (at most) payload with full fuel. That is crazy.
Their M-9 model is a lot better, with 300 lbs more useful load.
 
OH. I thought someone had completely disassembled a Maule in your hanger as a joke.
Carry on.

Just proof that taildraggers are better than tricycle gear :)
 
The big engine Maule’s have that problem. My MX7-180a had almost 1,000lbs. Tough to keep it in CG range with baggage for 4 but it could carry the weight.

200+ HP makes them a heavy lifting hot rod without the legal ability to use it.

By my estimation, the turbine Maules have about enough useful load for a pilot to carry enough fuel for a VFR pattern. ;)
 
Having the option to carry 85 gallons of fuel doesn't mean that you have to top it off every time you visit the pumps.

Yes, you almost want to treat a full load as a long distance ferry setup, or at least a long ETA setup. I happily fly an IO-540 with 60 gallons. I’m guessing some of those gallons are in some outer wing tanks with electric transfer pumps (?)

The Maules are not the most elegant, well thought out designs. Writers used to make fun of their habit of coming out with a ‘new model’ every year just to get magazine coverage; “hey, let’s take the rear seats out and call it a MX321”!

They are simple, old school aircraft. We were waved into the antique area at Oshkosh, 2 years running, despite having the proper signage displayed.

After some years of loving ownership, I can call them crude aircraft, with much affection. Reflex flaps that do nothing for speed as promised but make descents more pleasant. An extra notch of landing flaps that does absolutely nothing except provide a satisfying last notch for Walter Mitty fantasies. I can setup a steeper approach and a greased landing in a crossed up C172 easier than I can in a Maule which requires a blast of power to get the nose up from its not as steep power-off approach (actually the Cessnas like a bit of power too but it’s much easier to do).

But the satisfaction of 3-pointing a max crosswind landing using reflexed flaps and requiring a 270deg turn to exit the runway. Then having the tower point out the recently ground looped PIper Mirage off to the side with a collapsed gear.... ouch-priceless.

At 75% power and 2500 ft, you're burning 14 gph, and four hours plus a VFR reserve is about 63 gallons. However, if you are flying at 2000 rpm and 60% power (economy cruise), an IO-540 will burn around 10 gph and do about 110 kts IAS. Do you really need 70-85 gallons for a 4 hour / 440 nm flight when 45 gallons will do?
 
The M9 has a beefier landing gear and ironically the M7 (now built with it too) just needs the feds to sign the paperwork for the up gross.
 
I’ve always been a little surprised about the low gross weight / useful load of Maules - in every other way they seem like they should be a 182 or 180 in design. I have no time in them, maybe someone who actually has flown them can explain.

Look at the welds on one... not sure I’d want to carry a lot in a Maule lol
