Wing tip extensions?

[29singlespeed]

Is there a wingtip extension/mod for M5's and M4's to increase the wing length?

No. If you want a long wing you need to look for a 1984/1993 M7 33'8" wing span 10'6" flaps. Universal wing is 32' 11". that you can buy and put on a M5, You would be into for more than you could buy the long wing m7 for. Funny thing is they are so good there are none for sale. If one comes up it is gone real fast. Look for a M-6-235 or a late 80's early 90's MX7-235 The last good deal I saw on a mx7-235 was down in ID for around 50K about two months ago.

That's what I deduced. Thanks.

Clarification, I understood the early M6, late M6, and the M6 with Mod Kit for the 60" ailerons were all 32' 11" wings, just like the current "Universal Wing". The differences being aileron and flap length combinations and wing tips.

Understood the mid 80's thru early 90's MX7 were all "Short Wings", like the M5, unless they were changed after production to M6 or M7 wings or post 93 Universal wings.

The exception may have been a few wings that were modified with a spar repair/extension, when the kit/process was still allowed. I heard it was used by some to create M7 Long wings from M6 wings.

Perhaps some other folks know if the spar repair/extension kit/process was used to extend the shorter M5 and early MX7 wings to 32' 11" or 33' 8" length, before it was discontinued.

I would like the -7 flap option... that said .. so few maules come up I cant be super pickey in my price range 50-70k

Every Maule since the M5 has the -7 deg flap. However Trigears have 40 deg max flap down whilst Taildraggers are 48 deg.

Thanks, Jeremy!

I know there were some "approved" spar repairs and extensions. What are the details, rumors, half truths, or stories about longer wings. Please share historical, anecdotal or otherwise.

The early M4 round tip was convertible to the droop tip which added 12" overall to span. 29'10" to 30'10".
The early M6 droop tip wing was convertable to the later square tip wing. The kit included a rear spar extension but overall span remained at 32'11".
An M6 wing was re-engineered in Anchorage which added a few feet to the span. Flew slow but cruised slow. I saw it and talked with engineer but have forgotten the details.
Sumner Putman of AK extended M5 wings a few feet and added full length leading edge slats and fitted them to a PA14.
Maule used to have an approved spar repair splice kit.
Bob Sample STCd an upgross kit for the 33'8" longwing but it was prohibitively expensive.
A turbine 33'8" wing was engineered to a much higher gross weight on a one time STC for us.
Anybody else have info?

We would love to have leading edge slats and Fowler Flaps....

[chris.johnson]

I always wanted to turn my M5 droop tips over and call them winglets!

[BatMaule]

(Semi) Fowler flaps are not an unheard of possibility. Rumor has it that a certain "Bushwacker" pilot really likes all 10' per side of his. Probably never make it to the certified world though which is too bad.

I know the looonnnggg wing M6 that Jeremy refers to. Cool plane. A lot of wing outboard of the strut attach point! Other than the wing, it is kitted out pretty much the same as mine and it does cruise 10mph slower at the same power settings. I've never been PIC and tried to work that plane but it probably will land slower. Not sure I'd be willing to give up the cruise speed though as that is one of the things I really like about our planes.

i have seen an old black and yellow M5 running around AK that has been converted to an M6 by modifying and lengthening the stock M5 wings. never saw any of its paperwork, but its obvious by looking at it. dont know how they got away with that?
