Hiya all

You may remember I was looking at a Maule MX-7 180. Alright, I have some questions for you Maulers out there:

Isn´t the difference between a MX-7 and a M-7 that 5th seat? I ask that because this one HAS the fifth little baby-seat in the back while as far as I knew it shouldn´t

Another one. Let´s see. It has the Lyco O-360-C1F, but I can see a red line between the 1900 and the 2200 rpm!! Yes, I know it´s present in some airplanes, I´ve seen it before and I´ve flown some of them but, do all the MX-7 180 with a Lyco O-360-C1F have that line or could it be because of what I´m thiking? BTW, maybe it helps you know what I´m thinking if I say it. Maybe that blue needle between the throttle and the mixture is "fake" and they installed a fixed pitch prop. I didn´t really paid attention to that before, but it had to be one day, and that day was today. Those red lines scattered somewhere around the green arch use to be there to avoid "funny" vibrations in the prop, so that could be an explanation for me if the 1900-2200 red line is not usual in the model, and I don´t think it is.

What else? Anyone for a Broussard? You can have it in your hangar for $100K Good potentials on P&W R-985 engine and prop. Kind of joking... but just kind of

Jose,
A The MX planes have a shorter wing than the M-7. The MX is supposedly faster, but that hardly seems to be the point of a Maule. I used to have a MX-7-235, and in spite of the shorter wing it was a very good STOL plane. Personally, the only thing I didn't like were the small ailerons. My palne did not have a fifth seat.
Cheers
Jeff

From 1993 the MX7 and M7 have the same 32'11" wing. From 1984 to 1993 the MX7 has 30'10" and the M7 33'8".
Some of the early MX7's had an optional jump seat but limited legroom. They had an odd shaped left rear window.
The M7 upper longeron departs the wing root 3" higher than the MX7 allowing 3" more headroom in the rear area.
The M7 floor length is 5 1/2" longer than the MX7 and the rear door is larger thus allowing more rear seat space.
The early MX7 had 180hp and c.s.prop and 235hp.
The late MX7 had 180hp f.p. or c.s.prop, no 235hp.

That was data! Thanks both of you!

This one is an ´88 model, so it shouldn´t have a fixed pitch prop. In fact, it has the pitch needle, but then, is that red line in that rpm zone something usual or should I think they installed a F/P prop sometime in the past ans "forgot" to mention it? Because the "secondary" red line is just in that stupid regimes I tend to fly . I could only use, according to it, 1899 rpm or jump to 2201. Ok, you don´t cruise at 2000 rpm everyday, but no doubt it´s a cute detail being able to keep the engine running there when you pretend to hang it up in a short field landing, isn´t it?

Any thoughts? Anyone surprising me with a "my MX7-180 has that red line also"?

Jose

The "restricted operating range" you describe is a very common (almost universal) feature on virtually all O-360 engines equipped with constant speed props. It also appears on some engines with fixed pitch props.

Oh, yeah, forgot to note--look in the POH for the airplane. Oh, wait, Maule only makes one POH for all their planes .

MTV

Aaks!! On the C/S too!!? Seen it in some others airplanes with the O-360, but they all had been modified from a C/S to a F/P, that´s why my first thougt pointed there.

Not related to this, but a "Helix" just passed by and I had to mention it sounds like a UH-1 in stereo!!

Steroids too, those things will out climb any other helicopter

From 1993 the MX7 and M7 have the same 32'11" wing

Boy my day just keeps getting better!!

WHY!!? Tell me please!! I´ve been awarding for an explanation for two days now and you didn´t came with it!! Tell me! I´m glad your day were getting better, but you just screwed my weekend wondering why "From 1993 the MX7 and M7 have the same 32'11" wing" made you get so happy!

Longer wing, longer torque tube flaps and ailerons, better short field performance.

Todays homework: http://maules.com/Chronology.htm

Just to throw a wrench into the works, I believe there is more than one 32' 11" wing out there. I believe I've heard of the newer wing with the bigger ailerons refered to as the universal wing.

What he said!!
and sorry for making your weekend suck...

I think the only longer wing is the "A" Model wing this(32-11") is the Universal wing. ...(I said I think) so no wrench to throw..

Nah, what I was wondering was why YOU were getting happier while the only Maule´s ignorant here is ME

Whatever, today is my birthday and I don´t believe you, so let´s make a collect to buy a ´85 MX-7 180, a 2006 MX-7 180C and a meassuring tape for me. I don´t need a ribbon on it. Thanks.

I am just learning more every day! and happy to know more info about the MX-7 180. 1995 vs 1993...

The other 32'11" wing is the early M6 droop tip from 1981 to 1986, measured from the delta tip to delta tip, so not as much lift surface as the 1993 onward 'universal' wing. It had small ailerons and small rudder so not enough control. An upgrade kit was made available in 1986 and many of the M6 have been converted.

Is my present on his way?... anyways.

If a guy wich nickname reads "maule.com" says something about them, I´m pretty inclined to believe him

BTW Hottshot, with those wheels you sell you shouldn´t care about the wingspan, just feel ´em up with helium and go flying.

PM me with your adress and I'll see what I can do!


As far as the Helium it don't work to well try landing when your plane wants to go wheels up all the time....

There is when the fork you have on the plane as part of the MEL comes to play. Depending on where and how you use it, the plane will finally touch down or will increase its speed up to Mach 1 (that´s the reason of the delta wingtips on the M-6)
