May I suggest The "Maule M-7-260" package over at
http://www.fsnordic.net/file name is "M7260 v1.zip".
While the download weighs in at a modest 61MB, it is worth every second it takes to get it.
I downloaded it back on the 15th of this month and already have 38.6 hours logged on it. Hehehe thats more time than I have spent at work this week. IMHO it is a very nice and detailed plane, looks great, flies great, and I have not noticed a frame rate drop at all.
I was flying online the other day and four of us had this plane going at the same time and noone had a FPS drop. That alone has to say something about this plane.
Anyways, I guess ill stop blabbering now.

EDIT: Oops, I just noticed that this plane was already listed. sorry
