I have no idea really. Not necessarily doing it for weight savings but that will be a bonus

Make sure you follow Lars instructions for the application of the Oratex. Its better then the factory instructions. Little things like putting 2 layers of glue on aren’t mentioned in the factory material, and it makes a difference for sure. Lars didn't have his book out yet when I did mine, and the finish is ok, but things would have been better with some of his methods.

M5 has a span of 30'10" measured at wingtips. These are droop tips which also delta outwards at tips so not all lifting surface but faster cruise as the vortices are less than the squared off tips found on later models of M6 MX7 M7 M8 M9.

That is interesting info on the Maule droop tips! I have them on my Pacer with Plane Booster squared wings. The wing span at the end of the tips is 30'8". I've done a ton of Googling, but haven't found much info/discussion on those tips.

Wonder how performance compares to the more common(for Pacers) Sullivan Hoerner style tips?
