Firewall Knot Rudder

In order to be flown by a sport pilot, the resulting airplane must still meet the current regulations—1,320 pounds maximum gross weight, 120 knots max cruise speed, for example—but how it gets there is up to the builder. The large canopy pivots at the firewall, so it’s up and out of the way as you settle in. A nuance, perhaps.

The max stall speed is 45 knots and the max full-power cruising speed is 120 KCAS. Busted landing gear, shattered props, bent firewalls—and many more that probably didn’t make the reports because owners quickly stuck them back in the hangar and turned off the lights. GPH on 92 knots.

The pilot applied right rudder in an attempt to correct this, resulting in a ground loop. After arriving at the destination airstrip the student entered left downwind for Runway 13, resulting in a right quartering tailwind of about 5 knots. The airplane sustained substantial damage to the left wing.

We routinely taxi at 1200 rpm due to the low spray…[we] can cruise at 10 knots” in displacement mode, something a Goose can’t do. Early on a speed restriction of 130 knots was applied as a flutter issue. This was resolved on the kit version and led to cruising at 50% power and 120 knots, which proved to be the Gweduck’s sweet spot.

With the F2, the rudder and vertical stabilizer are changed, with the rudder becoming a much smaller surface than before. You can sit there with full back stick, full aileron one way and full rudder the other, and its perfectly controllable. You might ask what happens with crosswind landings when you take away rudder authority.
