Here’s my latest fascination:
It’s a quadcopter with 225mm arms, 8” propellers, a six-channel control board, 22mm motors, and an 11.1-volt, 1600mAh battery.
This is actually the second incarnation, the first having been built on a laser-cut 3mm plywood frame. Poorly-assembled connections resulted in a couple of spontaneous dives into the ground, resulting in two broken arms. This one has fiberglass-impregnated plastic arms and has survived one crash (though one of the original propellers didn’t survive—thank goodness for spares).
It successfully flew at a park in Houston this morning. I’ll need to do some fine-tuning, as it’s a little twitchy, and I plan to install 10” propellers as soon as I get them balanced. That should result in a longer flight time, because the props will produce more thrust at a given motor speed; at the moment, I hover at a little over 50% throttle. I’m also looking at higher-capacity batteries.
Once it’s tuned up nicely, I plan to find a small camera capable of recording video and flying around the countryside. I’m thinking a flight off of Lover’s Leap in Waco’s Cameron Park would be pretty spectacular, as would a dive off the bridge that spans the Red River on our way to Bill & Jo’s place.
