Please tell us a bit about your UAV interest
Just got a 3DR APM 2.6, trying to get the initial setup to work and having a nightmare with Mavlink.

"My bad, not sure how I ended up with that answer, it should have been 9 / (14.37 x 0.025) = 25.1 A..."
"Here's my stripboard circuit diagram in PowerPoint if it helps for easier understanding of where the leads actually areStripboard.pptx"
"James, one more thing:On the ardupilot website it states: 'Pin 54 to 62: You need to add 54 to the pin number to convert from an analog pin number to a digital pin number. So pin 54 is digital output pin on the A0 connector. Pin 58 is A4 etc.'I…"
"Good evening James,
I've just gone through the steps you indicated and the ardupilot.com link you sent but when I went to 'write params' after changing Ch7_Opt to Camera Trigger, it came up with a message saying: 'CH7_OPT has more than doubled the…"

"ah I see so the current board doesn't actually have a relay on it then? Yeah I think it will work swell, just sorting it out now :) Thank you so much once again!"
"Ah right, ok well I copied and pasted the script that you wrote in your comment above into Notepad, saved it as a .py file and then uploaded it to Mission Planner as you said to. Was I then supposed to click on 'Run Script' ? Do I need to take any…"
"James, would this work? Sounds like a good idea for something that requires more than 5V, although whilst the reed relay switch in the Thermal Knife circuit doesn't require more than 5V, the PP3 battery would then put 9V through the circuit, which…"
"Thanks James, yes apparently it was a synch for my colleagues to calibrate the ESCs with the RC transmitter and receiver yesterday, which is great news for us.
Interesting, thank you for the script that's really helpful. What I don't quite…"

"Ok, I've let the others know, thank you very much for that.
Do you know what the default throttle settings are for the SQ 20A?"

"Thank you James for the really helpful reply.
Ah I didn't notice that about the default throttle settings, maybe someone online like Richard (the commenter who posted the code mod for Mission Planner to enable ESC initialisation) would know what…"

"Thanks for the tip Crashpilot1000! I'm not in the workshop today but I've messaged the others in my group who are, to make sure that they flash the SQ 20A 4-in-1 ESCs with blheli. When you say adjust the pwm range, how will we know what to adjust it…"
"Thank you, Richard, for such a detailed reply! If one of our members hadn't somehow managed to score an RC transmitter this weekend, we would definitely have taken your very helpful advice! We appreciate the effort and the useful links."
"Oliver, Gary, thank you for your replies.
We fully agree and sympathise with the reasons why you have said what you have said and we are certainly aware that catastrophic and even fatal accidents can and do happen (even with a transmitter).
Whilst…"

"Thanks mP1, might do that with James' suggestion."
"Thanks for such a helpful and QUICK reply! Really appreciate it.
Setting the parameters according to the ESC's programmable settings and according to the instructions on copter.ardupilot.com is certainly possible for us because the instructions…"

Hello all, I am very much a newbie to RC and quadricopters but I'm working with a group of fellow students on constructing an autonomous quad for a university project. We are currently performing our initial setup. We do not have an RC transmitter…
