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 ?


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.

One big difference is the cruise speed 164 for the lycoming, and 190
for the Allison. But as you say the price difference is huge.

Thanks
