"Because, if you mean the ESC trouble it had, then it is not really a cube issue, if ESC's are 3.3v TTL level compatible.That was the bad combination of IO buffer voltage of 3v3 and ESC's that worked at 5v levels.for more details:…"
"APM1.0 / ardupilot mega shield is long time unsupported.
Much faster microcontrollers and more RAM/FLASH have enabled much nice features on newer hardware , like EKF.
That said, I bet what you have still flies :)
"It doesn't matter what tool you use to configure the ardupilot.
You could also run both GCS, be sure to check out APMPlanner2 or QGroundcontrol, so you don't need to involve windows in your operations."
"You need to engage a decent electronics engineer, it's trivial to step up the he voltage onboard the ship to a few hundred volts, and then reduce it onboard the UAV to whatever it needs.
Take tethered Solo kit as inspiration."
"For flying Solo as a video-tool, use Solex.
For flying it for photogrammetry, QGroundControl (QGC) is your best choice
- be sure to upgrade to OpenSolo or latest Community Solo firmware unless you installed a Green Cube or modified Solo cube."
"No, you won't damage motors by size only.
If you force motors to produce higher power (W) than designed for, they can be overheated and damaged.
You should look into the various ways ArduCopter can limit max throttle/current, and test properly. "
