I flew the last 50 minutes this evening to complete the 40 hour phase 1 test period on my RV-6.
It flies great - straight and true - and apart from needing leg fairings, wheel pants and paint I logged and fixed the following problems.
* Leaky fuel drain due to tiny chip of building FOD getting stuck in the "O" ring.
* Soft brakes fixed by bleeding with an ATS pressure tank. This was followed by binding brakes fixed by the installation of return springs on the master cylinders.
* 6kt to 7kt high reading error on the ASI/D100 traced to leaks in cheapo fittings on the back of the instruments and fixed by replacing them with decent Stein supplied fittings.
Empty weight in the current configuration is 1021 lb with a 1650 lb gross.
At 1360 lb and 72.56" cg Vso = 46 kt, Vx = 90 kt and Vy = 100 kt. I'm happy that the Vso and Vy are close - Vx is harder to extract from the data and might be the subject of more test flying
One slightly annoying characteristic that I haven't tracked down the cause for yet is the need for lots of right aileron trim when I slow to pattern speed and deploy the flaps. At cruise it flies feet and hands off with neutral elevator and aileron trim - and no rudder tab.
Now I'm looking forward to going places.
