Weather today was spectacular -- near 70F, wind was low, and not a cloud in the sky. Went out to Rancho San Antonio late afternoon and flew my little Q-Wing flying wing. I was flying pretty far out, and pretty high. My plane looked small up there, but I've had her out farther before (as I mentioned before, the Plantraco 900MHz RX/TX has much more range than I expected). Had full control and I was surfing on the light wind up there. Then I got momentarily distracted by some loud talk behind me and took my eyes off the plane. Just for a split second. When I looked back at the plane -- I couldn't find her. I put her into a continuous turn, gave some up elevator, tried to get the wings at an angle to reflect some light, but I could see nothing. Just miles and miles of blue sky. I cut throttle and kept her in what I hoped was a slow spiraling descent. Scanning, scanning, scanning the sky --- nothing.

Spent the next hour searching for her, but no luck. Gave a description and phone number to a park ranger passing by and called it a day as the park closed for the night.

Man, I had some nice gear in that plane. I hope someone finds it and turns it in. I'll go back tomorrow and continue my search.

In the meantime: Time to start building the Q-Wing v2.0.

Getting good at recycling the magnets from my dead Plantraco Bahoma cells. I killed my only two 160mAh Bahoma cells by running them down too low, so now the magnets live a second life in a 210mAh cell and a 160mAh cell from MaxAmps (nice cell). You absolutely must have a low temp soldering iron to do this -- or you'll kill the magnets. I took a bunch of pics of the process and I'll post a thread on this in the Micro forum soon. Here's a pic of my new 160mAh cell with the recycled magnets. Works great.

A bit windy over at Rancho San Antonio for my little "Q-Wing", but I got in some flying time this afternoon. Considering that she weighs 21g, has wingspan of about 13 inches, and has just a 7mm pager motor, she did pretty well.

The wind was around 7 or 8mph (I remembered to bring my wind meter thingie today) with gusts. I'd say that's the max wind she can reasonably fly in. If I kept straight into the wind, I could make slow forward progress, but if I got turned even a little bit to the side, she'd go squirting off to the side. Caught some major lift in a few spots and got her pretty high, close to 500ft I'd guess (that's high for this little plane). I'm amazed at the range of this little Plantraco 900MHz TX/RX system. Its not just for indoor!

Maybe tomorrow morning the wind will be less. All 3 of my batteries are now charged up... just waiting.

Here's some pics of my Q-Wing from a few days ago (another windy day).
