HI Guys,
These picture show a relief slot I opened up on the chin cowl. I tilted the motor to the left to move the header a bit more away from chin cowl. However, the chin cowl wraps tightly around the motor pump area so I started to get a crack where this slot is now. Looking at it, the edge of the pump flange was actually the closest part of the motor to any surface of the chin cowl. I opened up this slot, problem is resolved.
On to the best part. It seems like all the good things I loved about the Osmose are built-in to the PassPort, but to a greater degree. Again, my PassPort has the T-can and Osmsose horizontal stabilizer. Left rudder is Zero elevator mix. Right rudder is 2% down elevator. I mentioned earlier that my wings were 16.76 and 16.01 oz earlier. During calm day loop tracking, I determined that the left wing was heavy, and added aboug 1/8th oz to the right wing tip. Tracking was now nearly perfect inside and outside. When i dissasembled the plane, the "heavy" wing in flight was indeed the 16.76 oz wing, and the lighter wing had received the tip weight.
Rudder: This plane will shift your paradigm on what an effective rudder really is. I'm using the single-piece rudder on pull-pull cables, not the split rudder option. I am flying 1 1/8' throw each direction for all normal flight, including rolling loops and knife-edge loops. I am using a "full-swing" rate for stall turns. There is so little rudder used in flight, that you have to ensure your rudder setup is centering well.
Roll Mix: I am using 10% linear roll mix. Left rudder gets left aileron. Right rudder gets right aileron. However, due to the low rudder movement, the amount of aileron movement is also small. Later on I plan to try a point-mix to bring in the roll mix closer to the center of the stick. That should bring the overall number into the 3-4% range I believe.
Low-throttle has a point-mix so that the final click of power brings in 2% down elevator.
Thats it - no funny stuff. The plane draws great lines, it rock-solid-stable, point rolls with ease, can fly at very low airspeeds and still show almost zero rudder input. The integrated rolling stuff is executable to a high degree - plane carves it power on and power off no problem. The knife-edge loop is easy to get started, and easy to finish. Of course, you need to still shape it, but noteably, in the last 90 degrees, nothing funny is happenning to the plane.
Snap rolls have the same low-rate rudder, 9 deg up, 10 deg down for elevator, and 24 degrees up and down for the ailerons.
Spins are done on high rate elevator and high rate rudder only - no need for aileron.
Rolling circles? I did the best 2-roll opposite circle of my life the other day.
I landed and went home
Thanks,
Jim
