N46007 completed Phase one this morning; CHTs are settling; now all between 340-380 at low cruise (130 KIAS) I would expect that there will be further cooling for a given power setting when we get the wheel pants and leg fairings installed. I would expect another 10 KIAS at least for a given power setting. Have leaned EGTs to the 1350-11400 range and have fuel flow down in the 11-12 gph range. The injectors seem to pretty evenly matched as the EGT range for a given setting is less than 20 degrees. Will have to re-index the prop governor arm as do not get more than 2600 rpm at any time. Already tried adjusting the low pitch stop on the prop. Plan to place some insulation on the lower cowl to prevent deliberation from exhaust heat radiation. Do not have a hot tunnel at all. attribute this to good sealing (with baffling material and rtv) of the cabin heat valves. Full flap landings at forward CG require a good pull on the stick unless there is a lot of up trim already set. Largest direct crosswind encountered was 10 kts. Landing was fine with 1/3 flaps and 65 KIAS on short final at 2300 lbs. Standard wing down into the crosswind and rudder the aircraft straight down the runway. Chelton system is impressive; HITS provides guidance for the complete approach procedure; will update the databases and software next week. Trutrak AP handy but the Cheltons are easy to hand fly precisely. I have the TT 2.2 software and need an upgrade to 2.24 for the VNAV stuff to work properly. I did find that the magnetometer in the DigiFlite II is not useful. After calibration it is still off the Cheltons and the GRT by 10-15 degrees. Floscan transducer is very accurate; I adjusted my calibration value in the GRT EIS6000 down from 200 to 178. I now find that the agreement between amount used and actual is less than .2 gallon and this may be due to how closely I fill the tanks. The GRT Sport backup EFIS is usually set to map (XM weather) for flight but is on the engine page for start. With the dual battery setup all the avionics are perking about 2 minutes before start. They are disconnected from the starting primary bus. One thing I would suggest is that the AP should be on a toggle breaker. mine is pullable. I initially was told by the TT staff that starting with the AP on would not be a problem on that bus; reading there documentation suggest a different story. The truth is somewhere between. The Trutrak AP can be ON when the aircraft is started but the initialization sequence should be complete. Will post more later.Perhaps after a trip to the paint shop and a re-weighing.

Congrats to you on reaching a milestone... Thanks for the pireps on all your items too. I agree the Flowscan transducer is amazingly accurate.....
do not archive

Having an A&P and CFII I am well aware that the job is not done until the paperwork is correct. Thanks.
