As I continue with my build woes I have noticed a solder joint come loose twice. These little solder connections don't allow for much solder but too little doesn't offer much strength.
The buzzer goes on the bottom of the board, plus here's a link to the femto "manual". Look for M3 nylon screws on amazon
they have those little plastic box kits, with different sizes and you eill always need them on this hobby.

Betaflight does not see the motor. I desoldered it and soldered it on again. Still nothing. I need to look in blheli to see if it needs flashed maybe. Otherwise I guess I'll need parts.
You are correct. Certainly the big factor in the solder connection is the quality of the joint and not the quantity of the solder, so yes I always tin both items to be connected.Its not the amount of solder Jim it sounds more like the technique not making them stick. Try this...
Tin your pads by setting the solder on the pad then setting the iron on top to melt the solder. Tin your wires as normal. Now clean and tin your solder iron tip, set the wire on the pad and then touch the soldering iron to the wire. When it settles into the solder on the pad remove the iron and DO NOT blow on the joint to cool it. That's a newbie mistake that instantly makes a cold solder joint. If the smoke from the flux is an issue then blow high over the board to keep clean air in front of your face and not down towards the board to cool the joint.
If you do this a few times to get the hang of it and reputability you will never have another bad joint again.
I also ordered a new iron (temp controllable) and an extra fine tip.
The issue of heat mass/transfer did cross my mind. I'm hoping with temp control I can get the balance right. I might practice a bit to get the feel of it. I remeber in the David W. making temp recommendations in his tri build video on his site. I'll probably review that for a starting point. If need be I'll go to another tip or modify one to get the size and shape I'm after.I did the same thing and tried the extra fine tip. I'm not sure if I wasn't doing it right, but I found it difficult to get the tip hot enough to be useful. I eventually moved back to a standard small tip after repeatedly watching TJ make it look easy with a gigantic chisel tip.
I just ordered a tiny buzzer and 2 LED combo board, should make a great tail light. I can't wait for it to get here so I can hook it up and try it out. Only 1.38g
When you posted this I thought I might like one. If you're looking to alleviate yourself of some I might be able to help. Are you going to FFE this year?I accidentally ordered 15 of these. I wanted 3, but did not read they came in packs of 5.
Yes I realize it says 5pcs like 9 times. Yes I still missed it.
