Do you have fpv setup? I ask because can be helpful to use the on screen display feature or OSD to show warnings about why it is not arming. You may just need to configure your arm switch in the modes tab or it could be that it thinks throttle is above 0 when you try to arm or the quad thinks...

Usually if hear the first startup tones those just indicate the ESC/motor connection is good, the last couple tones indicate that it's getting some sort of "valid" signal from the FC. Honestly it kinda sounds like a dud you might want to just look to support for return/replacement. For binding...

I actually just wanted the 40A version of this but out of stock so have the slightly pricier higher amp one in the cart now. Have a couple receivers sitting around and DJI air unit for fpv for it probably like a month away from ordering though since working on getting a house and transitioning...

Check out the receiver and modes tabs in betaflight need to have receiver tab showing bars moving based on stick movement. If no movement in receiver tab work on that first, can change the protocol for receiver in the configurator tab in betaflight and can change which UART or input on FC is...

Oh noes haven't watched the vid quite yet but I had my first esc fire recently too it must just be that time of year :D. For me it happened on landing because I didn't put any tape on the CF arms and the esc shorted through the CF on the arm when it bounced off the frame on "landing". I...

Yah if you scroll down on the details page it's there too on tmotors site.

Sorry what is it your looking for exactly? The details page has the pin breakouts i think any betaflight setup vid would be enough plus the wiring diagram, to get most of it hooked up. Which part are you stuck on or particular component do you struggle with connecting?

Yah typically fine to just change protocol in betaflight or emu or cleanflight configurator and the esc will start using new protocol as soon as you power cycle. If it doesn't interpret the signal if will just not move. Doesn't hurt to upgrade esc firmware but generally protocol is detected on...

https://store-en.tmotor.com/h5/#/product?id=916 Click details can also usually find manual on manufacturer support page.

You can use the motors tab in betaflight to take the receiver out of the equation. Regarding measurements know an oscilloscope would see high speed ac like pulses that the esc puts into the motors but not sure how a voltmeter would react but I also haven't really tried testing an esc without a...

Just connecting won't harm anything either the problem could be mismatches in the config the firmware expects and the config the configurator writes to it but just connecting doesn't save any data from the configurator to the FC unless you explicitly hit a save/write config button.

When you use the configurator to connect to a quad there is a serial log (at least on betaflight) that show up on the top of the GUI can expand that a bit as soon as you connect you'll see print out of what the quad is reporting it's current version as, typically the configurator will also warn...

Yah it could work for a short time (especially if there are voltage regulators stepping down the input voltage they may have a pretty wide range of input). But running motors at higher than rated voltage will spin them faster for a short time or just cook the windings (too much voltage applied...

Gotcha I think there is a follow up step on newer versions of betaflight when flashing to apply some board specific config (think it prompted me on first reboot of the board after flashing). If can't find any info about that extra board specific configuration maybe try getting the firmware...

Yah actually I think the video out on FC should still pass through the vid signal even if it isn't overlaying anything would just triple check the video out pin on the FC (make sure right one not something just above or below or whatever typically I've seen vid in right next to vid out but might...

Good testing! So next thing I would verify is that the vtx out from FC to the vtx is working or can work (resolder or continuity test between vtx out from FC and video in on vtx). Even with no camera hooked up should see betaflight splash screen and osd settings. Make sure to enable osd in...

Yup that could work I like any blheli 32 ESCs. Since just doing a bicopter it would really be cheaper to just get some standalone 35A ESCs since you really only need two https://www.amazon.com/dp/B077ZT7NGV/ Would still want pdb but your FC might have enough voltage regulators or might be...

Cool yah just wanted to give the fair warning but not trying to scare you off :D. Regarding flight controllers the ones that support betaflight are all going to be pretty similar since they all depend on an ARM architecture (similar too mobile phone processor/MCU) at the heart of them. Intel...

Any FC can work just need the outputs to be able to be configured for driving servos that said if never done this before or new to building flying things I wouldn't suggest starting with bicopter since it is challenging and uncommon. I'd get an F4 based board most likely like omnibus F4 or if...

All you really hear is the buzz of the props and wind noise while flying but can be helpful to diagnose problems or just hear throttle response to help you stay more connected to the craft. The runcam has a mic and records audio onto SD card but I didn't try piping it through the vtx link.
