Here is my flight report.
First of all this is with only maybe 20 flights on the plane.
Triming was basically non existent. I added a little thrust offset and tip weight 1.5oz. Also I tweaked the flaps a tine bit. Because it is so stiff the flight was very predictable and it immediately showed when it did not like something, or if something was slightly off. In one flight the flaps screw was loose a little and it tweaked the flaps position in flight. I knew that instantly. We found the problem after that, tighten the screw a little, and we where back in business. Paul saw it and I confirmed the bug at the hotel. Yes I have flats on the rods, what happens if the rods are not perpendicular to the set screw when you tighten it it will stay there for a while and of course during the official flight it will move a couple of degrees enough to give you grief. This was about the extent of issues we had so far.
Per design I moved the stab up and added the dihedral to put it in clean air. This decision came after a discussion I had with Windy Urtnowsky. It was a perfect decision because the model tracks and locks is effortless.
I also moved the stab backwards to get more moment to turn the corner. Moment (aka Torque) is defined as distance from CG multiplied by force. For same force applied by the elevator the further back you apply it, it has more moment (torque) to turn the plane (change the AOA). I have to say, that box also received a check mark, because this bird turns so tight I have not found the edge yet. Yes I tried to find it.
Control system that is custom with a little Expo in both flaps and elevator combine that with the tracking ability make the round maneuvers a breeze. Put a check mark in that box too.
Because the build construction is composite and composite is over 400 times stronger than balsa (over 800 times if you compare ultimate tensile strength of carbon to ultimate tensile strength of balsa) there is no flex in the air frame anywhere so no funny business like: of one flaps flexing more than the other one, or wing torsion or flexing up and down during flight, there is none of that bull crap to deal with. Consequently I am flying very comfortable at 5.4-5.5s lap time. . The line tension is lighter because the model is relatively light but is everywhere, regardless how hard I hammer the corners, and after I realized that I had to change things in my flying and get rid of bad habits formed from the previous models.
This is with a crude setup. We have not even started to tap in the potential of this plane to this day and only God knows where the edge is. Well I want to know it too. My previous bird was an SV-12 model with a PA60 tuned pipe in it, and if I compare to that is like moving from a BMW M5 to a Bugatti Veyron. The difference is staggering. I just cant get enough of this bird.
It may sound bias but so far I did not hide anything. So take it with a grain of salt. My personal impression is that this is next generation model a leap over anything at very least I have done before.
