Now let's see ... if a 701 is the "Sky Jeep" and the 750 SD is the "Super Duty" (aka Ford F250!) then what does that make the "regular" 750 STOL ... a F150 pickup??? If it is a pickup, what does it need worse than anything? A third seat? Nah ... it needs a mud flap! ;>)
As a member of that elite fraternity that paints the belly of their plane white, it really bugs me when water or mud gets thrown up on that belly! After all, white belly airplane owners work very hard to develop the correct "patina" of evenly distributed dust, dirt, and exhaust stains ... and if carefully done and evenly distributed, you can "almost" convince someone that it is not dirty, but rather it is "off-white!"
HOWEVER, when that darned naked nose wheel treks across wet grass - it sprays the belly with droplets that absolutely ruins the "patina" with big ugly streaks and splotches! And we won't even mention what happens if you hit mud, or worse yet, a cow pile!
So, I recently noted on John Heather's first engine start video that he had a mud flap on his nose wheel and shamelessly copied it, with modifications:
Since I had down-sized my tires to 600x6x15's, I had plenty of room between the tire and the fork to mount the L's on the inside of the forks. I used .040 fabricated L's with doubler L's under the front 4" of the L. The flap is .063. On John Heather's flap, the L's are mounted "upside down" relative to mine, but give him a break ... he is in Australia (aka Down Under)! ;>) OK, the truth is he had to mount his on the outside of his Cruzer's forks for clearance purposes and therefore the L's have to be "upside down" to have a flange facing the exterior of the fork.
The entire assembly was brushed and clear-coated with ProtectaClear metal coating. I like this coating for small jobs as you can brush it with a foam brush but it is self-leveling so you get a nice finish and, it seems more durable than rattle-can clear coat. I used it on the fork and landing gear legs and it has held up well as you can see on that fork after 5+ years and 500+ hours!
The flap is slightly angled downward so that it will be parallel to the slip stream in normal flight attitude. I doubt it will cause much drag as it rides in the area shielded by the tire. We've had near-daily rains lately, but of course, as soon as I finished this it quit raining! So, a follow-up will be in order when wet weather returns. I've no doubt it will work well as many planes have similar flaps.
