After two FCs, three sets of motors, and 4 teardowns, I finally I figured out where the phantom noise was coming from with this frame ! :D :D :D
I needed to isolate the FC from the VTX. This allows the fc snug to be snug, but still tighten down the vtx.
I bent two shafts from a crash last session, so i put the 1408s back on. It needs a tune, but no more flyaways!
Its fun, but maybe the thrust in this situation isnt worth the weight.
if i swap motors, leds will make a return and maybe ill clean the frame :P

When you say "isolate the vtx from the FC" are you talking about physically, or electronically? I read that you were tightening them down, which makes me think you are talking about mounting hardware. You said you found where the noise was coming from, and I assumed you meant electrical noise in your video feed. Is that correct? If so, and you isolated the vTx from the FC, what did you do? I was looking for copper shielding, or an LC filter, but I didn't see anything outside the standard capacitor (btw, I like your heat shrink work on the cap). Did you twist the wires?
mechanical noise. I was getting crazy vibrations because of my stack mounting. a single nut on the top meant the entire stack was compressed. I put a nut between the fc and vtx so the fc can stay floaty, while the vtx can be tightened down. I did not twist the wires on the cap... they go straight across the top of the cap and down the side to give me the room i needed to stuff it between the top and bottom decks.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
