Mine is only that way when climbing out. Once I get up some speed, mine's like Larry's, just take my feet off and it'll straighten itself out. I DO have a "heavy" left wing though, although I suspect that's due to 150 pounds in the left seat, and none in the right. I plan to remedy that with a 5" round aluminum tube fuel tank in the right wing, killing two birds with one stone. I did another hour and a half this morning, playing with static ports and fuel totalizer, and another four landings on short strips. I flew 2.5 hours and did 22 landings at Fayetteville on Thursday, with the goal of perfecting the power off landing from downwind. The static port tweak got the bottom end of the airspeed indicator to be fairly accurate at the expense of the upper end, but the VSI is still crazy. Need more investigation there, but it makes me feel better that nobody else can figure it out either. Today I added a backup electric fuel pump, and tomorrow I'll wire it to the backup UPS battery mounted in the tail. Redundancy will be mine, and CG will move aft a little. I talked to Kim McCutcheon (president of the Aircraft Engine Historical Society and mechanical engineer A&P) today , and he commented that it takes an engine out landing to start thinking like I do now...going everywhere at 12,000'. Next weekend it's a 400 mile trip to Daytona Beach to Corvair College #9. Lots to do before then...mainly wiping all the oil and exhaust residue off the bottom for the first time in 35 hours. 73 hours on N56ML to date! I did manage my first high speed "missed approach" at Hazel Green Thursday, for Jim Hill's benefit. He was setting the timing on his KR at the time. When I landed at Moontown a few minutes later, my phone was ringing. Jim said "You mustav been going at least 200mph! Sweet sounding engine!". Yep, first time...
