"Actually, a full charge on 4S at 4.1V per cell is 16.4V, total. Based on your log, Voltage looks about right. As for voltage drop on take-off, you will have a definite drop once the motors spin-up under load. (My hex running 3805 motors weighing…"
"Love the Rocket Days! My wife was really into building and flying rockets.
This is my beast that will climb at 30'/s or 1800'/m. Imagine the altitude possibilities with a 35 - 40min flight time. And that's enough time to go up and come down…"
"When the Model Rocketry clubs come to the Dry Lake Beds here in Nevada, they get special permission from the FAA to do record height flights with their high power rockets. That would be a perfect time to hook-up with such a club and go for a…"
"I've been running DJI's E600 propulsion system on my Pixhawk hex with pretty good luck until recently (flight crash due to wrong PIDs using a heavier 6S battery than what I usually run on 4S).
DJI's E600 system uses 20A Opto ESCs, 415kV motors, and…"
"The 6S batteries have a lot more energy content than 4S batteries. Think of it this way, 4S is nominally 15.2V average, and 6S is nominally 22.8V, over a flight run. Let's suppose you use the same mAh rating for two different batteries, chose…"
"Yep, I run the same SD Card in my GoPro Hero 4 Black. Seems to do just fine.
Raw video off of the P3 looks really good in my opinion, even at 4K.
As said just about everywhere else, prop balance and proper dampers seem to be the key. My DYS has…"
"It's possible that when using the front mounted GoPro on the Iris that the balance (CG) was off, contributing to flight instability. I find that both my Hex (using Pixhawk) and my quad (using Naza V2) fly much better when I use the battery to…"
"So I have a couple questions about your Vortex 700 setup:
1) Are you using the Pixhawk F/C in lieu of the 3GX or Gpro F/C that came with the TREX 700?
2) Did you ever fly the Vortex 700 before using the Pixhawk?
3) Was tuning the Pixhawk with the…"
I use Dashware with Flytrex, and I have never tried overlaying my LOG / Bin files from my Pixhawk. I experimented a little with opening the file in Excel and parsing out the data I wanted from the GPS data lines.…"
Thanks a million. I had a decent flight today with settings I experimented with from "bench-top" testing. I think one problem I am noticing is that some movement (like end-point jerky-ness) in my video is due to the super flexible grey…"
