Inspired by Jack Hart's efforts to get more bang from his gasoline buck, I decided to attempt a couple streamlining projects. I added home made gear leg fairings, which I told the list about last year, I think. They added 2 mph to my normal cruise speed. I took them off later to adjust my toe-in by bending the gear legs. I finally got around to painting them and putting them back on last week.
This week I devised a mount for some old wheel pants that came off a Rans S-6. These are good pants/spats as they made a 4 mph difference in the Rans. Since the Slingshot is a good bit slower, I expected maybe 3 mph gain. They are worth 2 mph on the Slingshot. I don't intend to fly faster but rather same speed as before with less fuel burn. The most noticeable difference from adding the wheel pants was a change in trim requirement. I had to add a little nose down trim to compensate for the reduced drag below the aerodynamic center. Since I had a little nose up trim at cruise before the wheel pants were installed, this was a good thing.
I will take and post some photos after I paint the wheel pants, next week.
