In a 180' turn, copter pitch should become the opposite of world pitch & it does. In a pure copter frame program, she would have had to relearn the equilibrium pitch & flown away. -

Finally got VicaCopter spitting out KML files. -

It can plot autopilot runs in 3D, but can't disable those vertical white lines. -

The Goog doesn't do anaglyphs, but U can make them. It makes it much easier to visualize flights. Obviously JPG compression is hopeless. -

The first 3 waypoint mission is plotted in 3D. It definitely needs a lossless format. -

An autonomous hover comes to life in 3D. GPS captured a much tighter position than it was.

Attitude tracking was a bit better in the 3 waypoint mission. Cyclic integral limits were now all the way up to 2. -

Doppler shift is faster than position subtraction for determining horizontal velocity. -
Views: 330
But today's discovery was that position subtraction was faster than doppler shift for climb rate.

Still spotless after test flight operations. She did not land on this particular grass. -

It's time for training gear. That was no engine power & a much fatter shaft than the Corona, but probably inferior steel. -

More tests using locked down training gear. -

Result of lowpassed cyclic feedback. Lost tail rotor authority but cyclic was rock solid. -

The tail assembly seems to build up carpet fibers from test stand operations. -

Destroyed by carpet fibers but not broken. Blade tracking without the carpet stand is very hard.

$55 of blades for flybarless testing -

Spare parts from the Corona R now a blade balancer. -
Views: 295
The blade balancer finds the center of gravity quite nicely. -
Views: 298
But is worthless for balancing. #1 Corona bearings have too much friction #2 the blade grips R not perfectly equidistant from the pivot #3 the blades in this kind of balancer must B perfectly parallel -
Views: 283
The fastweigh is still the most accurate balancer, although the Corona is good enough for centering.

Outcome of full throttle test 1. With broken CCPM, this test had high oscillation and completely lost it. -
Views: 292
Outcome of full throttle test 2. With functional CCPM, she pitched forward violently. May have been aggrivated by the IMU being dislodged in test 1. -

The Jesus bolt failed at some point in flight operations. The head was hanging on by friction. Still many commutes remain before this head starts rotating. -

Have not reduced servo throw yet, for fear of not having enough collective range. -
