Larry Dudeck's 1/12th P-166
Power supplied by two 6v S400 motors, 2.33:1 gear boxes, 8x6 props. The battery is an 8XCP1700 pack.
Larry sent us an update after the Aircraft's first flight:
First flight was Saturday, 3/21. Set the timer for 6 minutes, and gave the P166 a good shove into a 5 MPH breeze. The twin pushers had lots of thrust, giving the P166 a very nice rate of climb. Took it up to a comfortable altitude. A little right aileron trim plus a lot of up elevator had it flying level. Eased the throttle back to a glide. The P166 looses altitude faster than what I would like, not exactly like a brick but a glider she isn't. Put the P166 into a stall, falls off to the left, nothing dramatic.
Cruised around, left circuits, right circuits, a couple of figure 8's. Nothing daring. It looks like it might be a handful in a slow, tight turn, as when trying to line up for a landing. The lack of dihedral might make for some interesting low and slow flying. No aerobatics for a while with this one.
Timer went off at 6 minutes, lined up for a landing into the wind. The wide flat bottom allowed a nice greaser of a landing, coming to rest in about 15 feet. The pack still had some reserve, perhaps a minute or two. The wind started to pick up, decided one flight was enough for the maiden as my knees were shaking.
The CofG seems to back a bit forward, I need to move the pack back a little. Next flight I'll move the pack back about an eigth of an inch.
On the 30th of July 2005 the Piaggio Website received the following, rather sad, email from Larry:
It is with heavy heart that I must report the loss of this plane. It stalled during a low, slow turn while preparing to land. The best winds for the flying site I use are either south or southwest. The day of the crash, the winds were from the east. In retrospect, I should have made the turn at a higher speed. The plane came down, nose first. The fuse was crushed back to the wing root. The only survivors were the wing and the empanage.
I don't know if I will make another fuse or not.
