Put To The Test
A customer of mine sent me this video of his recent test with power combo, on his Blackout Mini H with extended arms. Very impressive, to say the least.
I had a chance to meet up with some local Blackout fliers, a couple weeks back, and we had a blast flying course laps around a vacant school park (I will post the video when its ready). I have been battling a strange yaw issue, which made tip-toe around certain situations, but all-in-all it was a blast to fly in a new venue and share the fun.

http://www.eyeintheskyrc.com First run at the thrust testing went very well, apologies for the horrid lighting and glare on the watt meter. Improvements will be made for the next test.

I couldn''t catch a break today. I hit 4 different limbs, 4 different trees. A testament to the strength of the frame, as the 4th branch was about 30 feet up, and mini h tumbled all the way down. Not even a prop bent! A quick snippet of a series of dumb crashes.

A streak of both good and bad luck. Bad luck being my spotter lodged his V-tail in a tree just before this (which we recovered very quickly). I was determined to make him feel better, and I think I made it worse.
The good luck: I called the ground management group, and they zipped over and assessed the situation. Keeping in mind, this is not really something they consider not their responsibility, and that''s fair. But it just so happens they were going to be doing some trimming in the same area, and they just happened to have a 75-foot boom lift around the corner they were going to use in a couple of days. The supervisor gave him authorization to recover the quad, should it not fall out sooner. Early monday morning I got a call from them saying they were able to pluck it out of the tree, no problem. I lucked out in a big way. Thank you grounds management group, you saved my bacon!
After three days in a tree, powered on, the battery had a voltage of 1.37 volts upon recovery. lol. Don''t think I''ll be using that one again.
Total damage: 3 props and a battery.
