MX-7 235

Post by TxAgfisher »

Hello all. First, I already ran a search and did not see anything directly answering what I am looking for.

On the early 7 series airplanes (pre universal wing, spring gear, not long wing 7) there seems to be very little information out there that I can find. I pulled the comparison sheet on MauleFlight and see its the same wing as the M5 with shorter ailerons and longer flaps. Flaps also go to 48 degrees. Also, still has oleo gear obviously.

Does anyone have any real world experience with them? How do they perform? How much do you give up with the shorter wing? Anyone know the actual years they were produced?

Thanks
TJ Van Matre

There are a few stories in the archives about them. Give this a shot:

The results have M7s and some other MXs mixed in with them, so you may have to sort those out. But there's some pretty good info in there.

Pretty sure none of the M-7s had the short M-5 wing. I thought that from the M-6 on, they were all some version of a longer wing. Perhaps that's incorrect...

So in the progression of models, they had the M-4 with a short wing, then the M-5 with a short wing, then the M-6 with a long wing, then the M-7 back to a short wing again, and then later M-7 with another long wing??

I know there have been several slightly differing long wings, but I didn't realize that M-7s had gone back to the 4/5 short wing at first. Hard to see how that makes sense.

Thought the 7 had variations of the long wing with the MX7 having the short wing.

That's been my understanding as well.

Ok all, I think i have posted the wing lengths on here a couple of times.
M7-235 1984 to 1993 has 33'8" wing with long flap and short aileron.
About late '80s early '90s a longer aileron was available and shorter flap and this became the M7-235A
1993 onward the M7 got the universal wing 32'11" span
The M7 never had the shorter wings.
The MX7-235 and 180 had 30'10" square tip wing from 1985 to 1993 when the MX7-235 was discontinued and MX7-180 (A) (C) (AC) got 32'11" wings.

I own one they perform great the shorter wing supposedly helps in cruise performance. On a typical flight I will cruise around 120kts at 50-65% power. With performance cruise 75% I have occasionally seen 140kts or more depending on the winds.

I frequently land and take off from an ~800ft strip and have done so at max gross with no issues.

During a typical landing with light to medium braking I use maybe 400ft before I'm at taxi speeds.

Ah. I missed that we were talking about MX7 vs. M7. I saw the "7" in the original post, but didn't read the thread title. Sorry for adding to the confusion.

Is it basically a M5 wing with the taller/longer 7 fuse? I would imagine it has to have the bigger cabin to be considered a 7.

The MX7 fuselage is the same as the M5 and M6 and M8 fuselage, except the M5 does not have the mount points that accommodate the flap torquetube of the later models.
The M7 and MT7 and M9 fuselages are longer in the cabin and higher in the back but external length is same as X7 and 6 and 8 and 9

If I understand this correctly, a MX7 is essentially a M5 with different flaps.

I wonder why they backed off from having the 33'5 wing on the first M7-235s and went to the 32'11 wing after a certain date.... Did the wing cord length change????
