We were blessed with a fun & mostly uneventful flight to the ultimate destination of Airventure at OSH.
Take off weight: 2022 lbs. CG 99.9" (800 lbs. of people, fuel and baggage). Ballast was removed from the nose.
OAT: 87F (take off & landing) Take off distance was before midfield so less than (1/2 of 3740'=1890).
Fuel @ take off: 46.4 gallons. Landing: 18.6 = 27.8 used. Distance 460 NM @ 16 NMPG or Flightaware shows 537 miles = 19 statute MPG (includes take off and taxi fuel).
Titan 370 with 9.6:1 pistons, Superior cold air sump, SDS EI/EFI: Fuel Flow 15.6 at take off. Cruise FF ranged from 9.3-11.1 GPH @ RPM 2510-2530 CHT @ 388-417F. We kept the mixture rich enough to keep the CHT (380-418) & Oil temps (210-217F) comfortable. At Moberly, the exhaust pipe residue was grayish and minimal smoke residue on the prop.
Cruise PALT was mostly at 4500' (DALT 7100-7300').Take off DALT 2450', 3035' landing.
Highest KTAS: 181.5 @ 2500', Ground speed 192.3 knots (220 MPH). IAS average about 149 Knots.
AMPS: ~30 Amps for 5 minutes after startup. 13-14 for the rest of the flight with Nav & Strobe lights on (@ 2 Amps).
Weather: Starting wind was 170@20 KTS and near the destination changed to 254@47. Sky mostly clear in the South with some light turbulence in cruise and a lot of turbulence when landing. Wind near KMBY at 3000' was 54 knots, gusting 24 on the ground. We landed on the short runway 23, braked hard enough to avoid a back taxi. Brake heat shield temps after taxi were L=54C & R=67C.
Squawks: AP still seems to need some tweaking, the Hanka roll trim spring needs more plies. Also found the roll trim actuator was slipping a little inside the adel clamp. Bolus tape shredded on the top of the right strake at the wing intersection. Suspect the HPVC foam gap seal wasn't holding the cowl pressure in and blowing out the top of the strake which caused some more right roll than the weak trim spring compensate for and the #2 CHT ran warmer than usual. Probably is why the oil was a little warmer than usual too.
Start to shutdown time: 2h 41m 31s
ADS-B working well with the new SV-ADSB472 module and double bazooka antenna above the canard. The VOR receiver's double bazooka antenna also worked. Occasionally the panel indicated we had dropped out of radar coverage but still had ADSB ground stations in range.
Comments: This is the first long flight with a copilot that needs stick time for canard insurance. The dual HDX1000 panel's ability to quickly and easily reconfigure to display flight instruments and map eliminated the need to scan the entire panel. The Skyview Wifi was connected to several EFBs. The enhanced ADSB information displayed on the tablet provides additional info that isn't seen on the PFD. The features were explored, finding ways to reduce pilot work load. The copilot has a background with military avionics & simulators was pretty happy with all the information and features that were available. The fuel burn seemed high, but with ground speeds at around 220 MPH...."it burns gas & hauls ass". Hope to get some higher altitude cross countries with favorable winds, leaner mixture & explore economy cruise.
