Took my dinner up to the La Sierra trailhead the other day, somebody was flying a big F3J glider. I'm pretty sure it was an Orca. I watched him for about 45 minutes before he went home.
I really wish I brought my real camera, my phone's a little grainy.
Got me inspired to make another sailplane. This one will be a lot sportier than the Petrel, I'm doing a pod and boom fuselage and a V-tail. I'm running it off a 1300 mah 3s that weighs 1/3 as much as the big 4s I run the Petrel on. The Petrel is great for steady winds, 8 oz/sq ft wing loading isn't bad for a sloper but I want to go just a bit lighter to be able to soar in smaller slopes and lighter winds, and maybe be able to thermal too. I'm calling it the Aeronaut. Partial length wood spar, carbon fiber boom, 2ch (for now), 2m wingspan. Should be a fun project, I'm just waiting for the spar to dry.
