  • Schumacher PRO-SERIES 612-A-PE lead-acid battery charger – to charge the lead-acid batteries to power the Astroflight charger to charge the nicads at home (I don’t know why I swallowed the fly, I’ll probably die). 7-02-03 When charging my dad’s (6 volt) Packard battery it made the awful smoke of electronic doom. We don’t know why… but it did. R.I.P.
  • an Ikarus Bleriot III electric slowflyer that caught a nasty microburst at the Bergen County Silent Flyers field. The day was too windy but we really wanted to fly. It was hovering in the wind against a 10 mph headwind about 10 feet in the air and then it suddenly went down. It didn’t nose-in, it was as if the air around it got tired of holding up the plane and it went down. It hit gear-first, which would be good except that it hit hard and the thing was way to delicate… driving the gear into the struts into the basket into the servos into the motor into the frame into 5,000 pieces. c. 10-01.
