The Cobble made a second flight today, with a nice, no-stress landing this time. The revisions to the take-off dolly worked great, and she lifted off from the dolly without any problems at all. Only "oops," if I could call it that, is that I didn't set a timer on the Tx, like I do for my other planes. After flying around for a while, and thinking I should be hearing that count-down ticking already, I brought her in. Reviewing the video from the keychain camera, there was about 8 minutes between take-off and touch-down, but she was still flying fine.
