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

You might also want to check into the status of the diesel they've been
trying to get certified. That should be a reasonably priced aircraft
with performance similar to the 235 but using jet-A. I spoke with Ray
Maule about it last year, and he said it was going well, but I don't see
anything about it on their web site anymore.

From AvWeb:

This week at OSH, Maule debuted an M-9 fitted with SMA's SR 305-230 aerodiesel,
which was first certified in Europe a while ago and is now poised to make
inroads in the U.S.

I spoke with SMA (France) last week, at their tent at Oshkosh. They said
currently only Jet-A is certified. Diesel is not approved. Too many BTU's in
diesel, from what I understand. To many variations in diesel fuel. (Their
words)

Diamond Star's diesel burns Jet-A or regular diesel fuel and is certified as
such. Their engine is made by Thielert of Germany

Seems like a very fine toy. Wish we had one... let's see, we've got Jet-A
on our lit grass strip. Imagine a night landing in the back yard with the
whine of that turbine as we select beta thrust. Wheeeee!

.... perhaps add some amphious floats.

Just need to increase our wealth by an order of magnitude... or two.
