• Glide ratio on Maules

Posted: **Tue Feb 26, 2019 12:27 pm**

I canâ€™t get my short wing MX-7-180 to glide anywhere near 1.5 nm per 1,000 ft.

I guess that drag from 31â€ bushwheels and bare undercarriage legs does significantly reduce the glide ratio, and perhaps also the â€œbest glideâ€ IAS.

I thought all '7s' used the 32'11" universal wing, no?

(with thanks to Jeremy) the older MX-7s have the short wing:

'89/93 M7(A) 33'8" sqr tip, 126" -7/0/24/40/48 flap, 60"x17" aileron
'93 on all 32'11" sqr tip, 119" -7/0/24/40/(48) flap, 60"x17" aileron
all flap chords are 15"

Incidentally, after about 500 hrs in my short wing 180 hp MX-7, I flew a 235 with 33â€™ 8â€ wing the other day. Climb performance was staggering, but it felt less comfortable/controllable in turbulence and gusty crosswinds. Maybe the â€œbestâ€ is what weâ€™re used to...
