Backwards figure 8's


So the most challenging trick in a fixed pitch copter is the backwards figure 8. Don't even bother in an airplane. Concluded we have trouble
seeing roll attitude from 10 oclock. The solution: nose-in/sideways passes, sideways in and out, and backwards figure 8's. They're probably
not possible without a heading hold gyro, and in no circumstances can they be fast.

In other news, the copter hit 50. 50 hours of flying. Would U believe the first few hours were spent just trying to debug the receiver? The
controls randomly froze after a few seconds of hovering. Other times the motor would stop at random points. The controls wouldn't return
until several minutes after it crashed, usually in the form of sudden motor spins after several minutes of prodding. Took several days to
figure out the crystal was loose.

Would U believe the very first flight resulted in a hover with the copter spinning out of control? Didn't even try again that day. Only a
day later realized the solution was to invert the gyro.

Hard to believe it was once that hard.
