I've had a similar issue where my quad wouldn't respond and it ended up slamming into the side of a concrete building right before narrowly missing a parking lot of cars. Luckily nothing or nobody else was hurt but the quad. The 3 axis…"
Hi All, here is my 250 FPV Racer I designed and 3D printed. It uses a mini APM as the flight controller and also has a GPS and telemetry for missions. The arms are 15mm carbon tubes with SN20A esc's in the arms. The files can be downloaded…
The power requirement to spin the propeller will be the same. As the cell voltage drops the current draw will have to increase in order to meet the same amount of power. P = I x V"
"I use Simplify3D to slice my files. It fills in all the overhangs over a specified angle with support and the supports are easily removed. Here is an example video of removing the supports. https://www.youtube.com/watch?v=lHqRY4mGJIM&t=6m0s "
"I previously had the RFD900 packaged in my 9xr and didn't notice any problems though the air volume is less in a JR module. Regardless, more cooling is better than less. There is a ventilated cover on Thingiverse now. Cheers."
Hi all, I designed a mount for the RFD900+ which goes in a JR module bay so that I can have long range telemetry with a bluetooth bridge for my smartphone / computer. The module uses the transmitter's battery as a power source. Also, you need to…
"Hi Leonard,
I did a cogging test with 12" props and the quadcopter bolted to a weighted down tripod. Turns out there are two hardware issues. The first issue was that one of the motors had a loose stator that would rotate until the wires stopped…"
I'm a little late to the party but I hope I can still get some help on why my quad crashed twice during autotune. I attached the log files but I'm still learning how to use Mission Planner.
"Looks like a shift in the COG maybe caused the crash? If I had to guess he probably didn't secure the battery well after changing it. Also, looks like the battery was cut with the propellers as the motors were still spinning when it was upside down…"
