Maule Turbine

Does anyone have any experience with the Maule with the Allison turbine
engine ? The Maule with the Lycombing IO-540 is $170.M , where the
MT7-420 is going for $470.M new. I would have to add about $75.M in
options for either bird. What do you think about the Allison turbine in
a Maule ?

Thanks

You are joking, right?
Look, the Maule is a fine airplane and does it's thing well, which is short
field and grass operations... It is not a turbine bird, and installing one
is a waste of money... Unless you are going into the bush of africa or asia
where 100LL is not available, stick to the Lycoming...

I was not talking about a conversion, you can buy a new Maule from the
factory with the Allison engine. I was looking at the difference of
cruise speed 164 with the Lycoming as opposed to 190 with the Allsion.
The 2800 fpm climb is also tempting.

The slower Maule will go a lot further between fill ups.

This is true. 15gph as opposed to 25 for the turbine.

15 vs. 25gph for different speeds, right? What are the fuel consumptions
for the same speed at cruise altitudes (10-20K)?

To be fair you should also add in the extra 5 gallons the turbine can
carry (in situations where you're at gross).

You might want to have the factory take you for a ride to see what 190mph is
like inside of a fabric covered fuselage with angular otlines....

Yes , without a doubt i would want a demo ride. A cruise speed of 164 is
not bad for a
STOL bird, 190 is smoking.

I recently flew a local pilots, new 260 Maule... I didn't see anything
approaching 164...

The turbine carries 35 pounds more and takes the same distance to clear a
50' obstacle. The major difference is the 2800 fpm climb rate versus the
1500 fpm for the piston engine. The turbine goes for $450,000. There are
several models of 235 hp planes, one of which costs $139,600.

So. That climb rate will set you back over $300,000 and burn twice as much
fuel. It wouldn't be worth it to me.
