@SimonDale @jpmreece @GVG_Air - Following on from comments in
Next Project - A Mini Drone Build - Mini Quads - Drone Hub
The Martin 3 takes shape pic 1… And BEFORE anyone says, the props are on the wrong place or this is wrong, I likely know about it. I’m honest enough to say if someone spots something that is wrong, like the props are likely in the wrong places. They were just put on to test they fit, both the shaft and the size of the prop. As you can see they do!
Also the electronics are not installed, well not all anyway, those that are installed are not connected - pic 2

There will be further updates as time and work on this one permits…
As always constructive criticism and feedback is welcome, but be gentle…

Looking forward to it.
The updates - not the criticism.
I love seeing builds taking shape.

Off to a good start I think

Yep, good progress, but I have a question about the wires for the motors…
they’re too long, but do cut them shorter or wrap/cable tie them?
I can see pros and cons, like leaving the longer to allow for future maintenance, but cutting them makes for a tidier build…
I’d like to hear some of your thoughts…

Apparently the impact on aerodynamics is negligible at drone speeds so all I can think of is snagging risk if you end up in the thickets.

Thanks GVG_Air, yes, I didn’t think of that so I think I’ll look at shortening them, not completely but enough to reduce the snaggability (if that’s a word)!
So now I have an issue, carefully connected the motors to the ESC/stack and took this pic…
Connected BetaFlight and checked everything looked ok, it did.
So I disconnected BF and connected a PSU, set to 6S/22.2volts max 10Amps. Reconnected to BF and tested the first motor and got SMOKE from the motor being tested!!!
I wasn’t aware these came with smoke trails? on checking, they don’t!
What would cause this problem?
I’ve checked for shorts and other issues, but only the motor being tested smokes, I’ve only tested two motors for very short period.
HELP!
UPDATE - Sorted! The motor mounting screws are too long and were pinching the wire. Having spotted and removed offending screws, smoke got away! Now to find some shorter screws…
