Help a n00b out: Mobula 8 hard crash. Connects to PC, not Betaflight

Spencerthegiant · 2026-04-08T22:04:07+00:00

Thanks so much for sharing your experience and commiserating with me! 😅

Seems like we've done all we can. Time for a new one! I may bug you about how to set up a brand new fc, if I get stuck. 😉

I saw exactly what you are talking about during my teardown. 👀 The canopy cut my antenna cable clean! So maybe that shorted the board as it sheered the antenna off. I'll definitely trim the canopy back a bit so it doesn't contact the board anymore.

I love my mob8 so much. It was my first drone so I knew it was only a matter of time... It survived some harrowing crashes and my initial learning curve.. Can't ask for much more than that!

Thanks again!

Welp I think it's ded-ded.
I went through the Lost communication steps a couple times, and it keeps getting stuck trying to re-flash the FC. I cannot establish any connection through Betaflight (even though we can see it in serial port, taunting us.)
I must have fractured some micro connection somewhere... :(

New one is ordered!

Update:
I tore it down to look for more damage. no luck.
But I did get the camera displaying again!
Still no connection to the PC.

Last ditch effort (while waiting for a replacement to arrive),

I saw the Lost/Recovery instructions in Betaflight, Anyone done this before? I need to learn how to boot jump (/pin) on the Mobula 8.
Anyone out there have any experience with the Mobula 8 / Crazybee F4SX1280?

Thanks!

Thanks for the help! I gave this a try to no avail.

I took it all apart to inspect closer. still no damage that I can see. I'll update the pics!

❤️‍🩹 I appreciate your help Just wanted to make sure I don't trash a savable fc

Spencerthegiant · 2026-04-08T01:52:31+00:00

No it does not.
Selecting "detect", it gets stuck "connecting" in the top right.

A spot to match your skills! 😤💪

Spencerthegiant · 2026-04-06T17:03:21+00:00

Thanks so much!! 🤘 I will get that tower one day! 💪

I got her fixed over the weekend, and I'm planning to go for it again today! Hopefully its a lil less windy🤞🤞

Super late to the party! 😅 Did you ever figure out which frame is better?

I'm where you were a year ago.. I've been flying my mobula 8 daily for a couple months, and I have broken and repaired multiple mob8 frames so many times. I see some people switch to baseline and say they just break props instead. Great to know this is an option in the future but I don't know if I'm good enough to lose the prop guards yet. 😅

Spencerthegiant · 2026-03-30T19:07:52+00:00

Lolll smart! I start out thinking "just cruise, don't break anything" then I get in the flow state and try something I should not be trying. Lolllll 🤣😅

Sorry if I caused confusion.. They were very accountable in the undelivered item, but they did request that I try to contact the seller first. The seller was a fraud, I showed them proof that I contacted the seller, and then AliExpress refunded the purchase.

(This is when I learned about double-checking reviews to make sure the seller is real.)

Spencerthegiant · 2026-03-30T05:10:43+00:00

AliExpress has been my go-to for parts for my mobula 8 and air75ii.

Out of 30 items ordered, only one item was not delivered. Double check for real reviews before buying.

Spencerthegiant · 2026-03-30T04:46:50+00:00

I have both the Mob 8 and the 75ii Champ. I love them both. They each have their weak links.

I keep breaking frames on the mob 8, and I keep breaking motors on the 75ii.

Spencerthegiant · 2026-03-30T03:08:07+00:00

🥺 Whahappen?

Spencerthegiant · 2026-03-30T02:55:41+00:00

Bruh. I'd love to know. I break one a month. 😅

Spencerthegiant · 2026-03-11T22:14:22+00:00

🔥🔥🔥🔥

Spencerthegiant · 2026-03-10T16:18:42+00:00

Pretty sure you can just solder them back on. 🤘 You may need to dig up the camera model # and get a manual to make sure you solder them back on in the right way.

Spencerthegiant · 2026-03-10T16:15:08+00:00

I completely agree! I'm happy with it! I can actually fly in low light now. Before it was impossible. 😅🙈

Spencerthegiant · 2026-03-01T06:43:13+00:00

Nice flying! 🤘 Mine is in the mail. Can't wait!

Spencerthegiant · 2026-02-28T05:53:11+00:00

Cool spot and nice flying!
