Pilots: Alvaro Cesar

Alvaro and I met up to give nil wind takeoffs another Go. My takeoff was maximum effort and liftoff was just under maximum running speed. Wasn't sure where I was headed. With trim set to slow and throttled back the old Vittorazi just climbed up to 700 feet. I decided to fly to the beach and Alvaro stayed in the area to practice. Cruising along the beach deck I decided to practice the pitch pendulum.
On the way back, I checked out a paracamp site. Since I was now on the deck again, I flew the abandoned RR tracks back to the mainland, passing over the fish house I worked at in 1981-2 while studying to become a commercial pilot. Got a bit adventurous and flew a shortcut to open country over the marina.
Once arriving at the LZ, I decided to perform a speed check on my APCO Lift 26m. As expected, the TAS was slightly faster than the 28m. I was running data through an E6B flight computer and determined you must perform the test in both directions and into the wind. Well we didn't have any wind to speak..

Results at an approx test weight of 258 lbs and 11.13 lbs per sq meter proj.
Full reflex - 31 mph
Adding ful spd bar 40 mph

After the speed test, I climbed up to 250 feet for dead stick practice targeting my car. Missing by 100 feet I decided to give it another go.

Mishap:
I finally taught myself to turn toward the wing when it drops after landing. It fell to my left this time. I didn't catch that the right riser wasn't on top, (Normal for me) So when I disconnected the right riser and continued to turn to my left I caused a riser twist. On takeoff the twisted area was above the mallions and tightened its grip on my brake line. That's why the wing pulled right after releasing liftoff brakes; the right side didn't release fully being held by the twist. I got it sorted out in the air thus allowing me to shoot another dead stick to an acceptable spot landing. Early on, I envisioned having to land using the right brake line above the twist.
