Making an AIO Cam/VTX That is ACTUALLY Less than 2.8 Grams - The AKK S2/BS2: Shave it DRY!
NOTE: AKK S2 is on sale again in the AKK AliEx Store, only $16.19 EACH!
A few weeks ago I Stumbled across the AKK S2 on flash sale; it was half price on AKK's AliEx Store. That is a camera advertised at 2.8 grams for $US12.70!!!
Really amazing, I thought... until one of my friends in the WHOOP community pointed out that weight was without antenna. Somewhat disheartened, I waited for my cameras to arrive; and sure enough, when they got here (pretty quickly, though... AKK ships via ePacket) they weighed in at 4.2 and 4.28 grams each. Hoping to get somewhere close to the advertised weight of 2.8 grams, I started taking parts off and weighing them.
Whuff... as much as I prefer the 4-lobe CPW, that thing is HEAVY.
And that high-quality 26ga silicone wire with JST-SH plug is convenient; but it's a third of a gram.
Please note that if you are going to remove this wire for lighter stuff as I did, you'll have to remove this epoxy potting. This requires considerable care, and you have to apply heat with your soldering iron to remove it safely; there is a capacitor inside there just begging to be broken off if you try to pick the potting off cold.
You may not want to bother, especially if your install allows you to keep your wires under 15-20mm long.
For ultimate convenience, they include an adapter which will allow you to plug the S2 directly to any 1S battery with a MOLEX/Losi/Walkera connector; I highly recommend you use this IMMEDIATELY to test the unit and make sure it's okay before you confirm receipt of product on AliEx.
NOTE: Be wary of the polarity, as there are many manufacturers who use this connector, and they like to switch (+) and (-) on the battery.
Okaaaayyy... now THAT's what I'm talking about! IT ALL ADDS UP!!!
So looking at my other cameras, I spotted this spare Dipole off my BoldClash F-02; man, it sure is a lot lighter than that cloverleaf. But I think I can STILL do better.
Oh, HELL YEAH! Even I was surprised at how much that heat shrink adds.
Here I've installed the skinned dipole and 0.25mm shellac-coated wires; now my 4.25 gram fat piglet of a camera is a svelte 2.83 grams. but that STILL isn't under 2.8 grams, dammit. Time for the final cut...
I know... the switch isn't much. But I really don't need it as the camera is easily accessible, and I can change the channels easily enough with a tweezer. I don't change my channel very often anyways, so it was worth it to see if I could break 2.8 grams.
There you have it guys! An AIO Cam/VTX that is ACTUALLY less than 2.8 grams ready to use!
Now if I could only drop my own weight that easily...
