This is my first mid/long range build, and it was been far from trouble free, and its not close to over yet....
I killed 2 airbot f4 pro's trying to solder to the terrible tiny pads on some spots, gave up, and got an f4 v5 instead.
I killed one of the 4 in 1 ESCs too, just clumsily knocked a surface mount diode or something right off while handling. Whatever solder they use is terribly brittle on some of these things. Just as well, cant see how theyd have held up in even the first crash, of which there will likely be many.
At some point, ill wanna get a crossfire module for my T16 and a matching nano RX for this thing, but meanwhile, i'll be happy just to get the darn thing in the air.
The plan is to use full-up iNav with this thing, and have position hold, waypoints, the whole shebang. It fits an 1800mah which isnt huge, but hopefully with the bigger props will give me reasonable flight time. The motors are 1700kv, and while ill probably usually fly it on 4s the idea is to be able to upgrade to 6s with no hardware changes. FC runs on regulated 5v off the ESC, and the VTX has its own 12V regulator right off the battery.
Compared to my last build this has been the opposite of cheap! Lets hope it flies nice.
It will carry my Hawkeye firefly 6s, which is the best cam I own, and will do 4k and has a gyro image stabilization. Hoping for nice footage, as I live way out in the country now, and there is tons of lovely greenery to fly over and through and around and probably into.
So as of 6/8/2019 its flyable! Al lot of annoying things went wrong during this build, but after all the frustration it was nice to see it in the air. Manual angle and horizon modes fly fine, and its very steady in the air, but alt hold and pos hold didnt seem to want to engage, despite having plenty of satellites. I'll be checking out the blackbox logs hopefully they will provide some answer? blackbox is new to me, i have more experience with the pixhawk for real navigation stuff, iNav is new to me. When I get my nav modes sorted out and some decent footage to show I'll get that up here too :-)

Where did you buy that "human intestine lining" 3-D printer filament?
lol well the color was meant to be "red". It's a cheap TPU filament I got off Amazon. https://www.amazon.com/gp/product/B07P1TDLC6/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
I bought this kind because it has a comparitively high shore hardness, which lets it feed more reliably in bowden extruder printers like the ones i have. The parts of course come out less squishy than with other TPU filaments, but still quite durable and flexible enough for my purposes.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

after a long break from flying, ive gotten back to it a little. I got this fellow out and the position and altitude hold work alright, with a bit of stuttering when they get close to the ground, im guessing thats propwash from ground effect or some such. RTH however, causes the thing to just go bonkers. Flew over my house and landed in the other yard, ejected the battery 30 feet, but fortunately no damage other that a few nicks on the props. I've added a lost model buzzer to it, and a filter cap, and i hope to get it out again soon.
