Tree Maiden

22 Jul 2015

Another night flight, this one was a little more intentional.

I’ve been getting better at line-of-sight, so I took it through the trees a little. Predictable crashes to be had there. Dust was fun to get the reflectance in the LED panel but not worth the follow-up cleaning (wet wipes and pressurized aircan).

Crashes:

• 2 trees grazes, causing minor prop chipping and folding one prop arm (1 trunk, 1 branch overhead while FPV)
• 2 inversions, and somehow made a flat spin? that was a bit of a surprise - and again: predictably crashed.

I’ve since learned that one needs to teach their co-pilots (spectators / spotters) how to indicate directional obstacles. And, while my line-of-sight flying on this copter’s improving, I’m still very much a FPV rookie.

A good obstacle alery has three traits:

1. Obstacle type
   • tree / stump / fence / person (person implies critical stop)
2. Directions
   • High / Low (up/down)
   • Front / Back (ahead/behind)
   • Left / Right
3. Criticality
   • Near
   • Now
4. “DROP!”
   • fall-out-of-the-sky mode, critical problem imminent

Next Purchases:

• replacement d4r-ii antennae (buy a pair, or three)
• gemfan props replacements (5030 and 5045)
• AA batteries or LiPo for Turnigy 9x

Next configuration:

• f/s on d4r-ii
• dominator DVR
• PID tweaks? investigate non-AnthonyRC protune with acceptable angle mode
• Turnigy 9x LiPo mod
