Today was the first time I have managed to get away and fly my helis in weeks. I took my little brother to his first ever fun-fly, and despite the periodic rain-storms, I'm pretty sure he had a good time. He hovered his T-Rex 450 on his first try, so I'm pretty impressed - all that sim time seems to have paid off. I did it the hard way, and it took me a very long time to get the hang of it!
My V-Bar troubles seem to be over, thanks to the generous help of MrMel. My Logo 600 flies like a dream, it's just so locked in and goes exactly where you put it. The Logo 500 also flies great, it's set up much more aggressively than the 600 and just zips around the sky. Only downside is that it gets through it's 3700mAh 6S packs in only about four and a half minutes, vs the 600's nine minutes. I believe that three minutes into my second flight with the 500 I had a thermal shutdown on the Jazz ESC however, and it was a very cold day. Something I need to investigate.
That's all for how. Here's a hastily-shot video of my Logo 600 in flight.
