Ok so i built a kit with no issues flew a lot crashed more fixed repaired replaced and now trying to build my own here are specs
CLRACING F4S "S" AIO FLIGHT CONTROLLER - V1.5 - CLF4S
SPEDIX 30A 4 IN 1 ESC 2-4S
BROTHERHOBBY DEADPOOL 2306 2450KV MOTOR - RETURNER R5
all went together just fine no issues flashed firmware with newest betaflight for my fc and went for maiden flight. armed it no issue props spin but increased throttle and wobble wobble wobble ok shut down check all noob mistakes there are none motors on right spinning correct direction props good too. go out try again get it in air maybe 3 feet wobble horribly and needed more throttle to take off then last one as well. i can not seem to get rid of this wobble i have tried all the google fixes with messing with PIDS and reflashing recalibrating esc and so on. no smoke no burning smell no issues at all except wobbling and i dont think its flyable as it wobbles that bad. i need help bad please!!
 
there are several different causes for oscillations, and there's no single solution that works for everybody. The main causes are electrical noise, mechanical noise (vibration) and bad tune. So first, are you 100% positive you flashed your flight controller with the correct firmware? Go into your CLI, type VERSION then hit enter to see the firmware version you have. Also, do you have a capacitor soldered onto the battery leads? Those Deadpools are power hungry. Is your flight controller soft-mounted?

it. could be tune but not sure where to start im a noob used default with no luck. im about to add capacitor right now and test

version is good soft mounted as in the rubber rings in holes yes. added capacitor still shaking
 
Yeh, that's not typical and with default BF settings it should be flying quite well. The only thing I can suggest ATM is to reflash your firmware (with full chip erase), calibrate your ESCs then set protocol to DShot 600 and check everywhere for iffy looking solder joints.
 
I'm thinking vibes. Any loose wires touching the FC? I tend to stuff thin foam padding that comes with all the parts packaging I order in between the boards in my stacks.
I saw similar behavior with a build I was having fun with and trying PWM. Thought the FC was bad but I think now it was just all the extra wires rattling around cause the boards works now for a different build.

im an idiot...... soooo somehow my board orientation was offset by 45 and i zeroed it and boom oy so dumb.... yep flies smoother then hot knife in butter now. thanks guys
