I have a happymodel cross f4, it got unplugged by my dog while esc 4 was updating to blujay and I thought it was bricked for almost 2 years then I saw a video where you plug it in, go to JESC configurator and reflash all ESC's, then back to blujay and flash all 4 ESC's and now I have a 75mm whoop again. I just need 1s batteries since all 1s I have just got tossed. They were old, gnb27 connector 450 gnbs. So stoked to have my cross f4 working
I generally start with checking the wire connection at the motor and at the flight controller. In most cases, the wire is breaking off inside of the insulation.
Good call! This one was a little different having two motors going out at once, so I skipped that. But more recently I've been using tweezers to lightly pull at the wires near the motor bell and have found some broken.
@@FPV_Cam I completely agree. Two motors at the same time generally means that is related to the ESCs. I guess what I meant to say was that after the reflash, and seeing that one of them still didn't work, that's when I would have checked the wires. Kudos for finding the solder blob, I probably wouldn't have noticed it. But now I'm going to be paranoid about solder blobs whenever I solder on the board 😆
@@TyranttFPV ahh yeah good point! I think there's a lack of people diagnosing their problem and explaining why they check what they do, for me that's incredibly helpful to see how people think and what their mindset is. I definitely got lucky, and maybe because I had extra lighting on for the video I happened to notice it, but I'm with you, might start just IPA and toothbrush scrubbing a board down once it's built to help with it!
@@FPV_Cam oh man, sorry about my last message. I used speech to text and it horribly failed me. I just fixed it. But I agree. Learning how to troubleshoot will make this hobby a lot easier. I definitely remember struggling with the idea of troubleshooting various parts when I first started flying. Life definitely became easier once I started to figure it out
I don't know of any really small escs that wouldn't add a ton of weight to a whoop, that's the only problem with AIOs it's easy to have something break and make the board more or less useless
it worked because it wasnt leveled before once you arm the drone it tries to level itself, one motor turns fast one may not turn at all you should have just moved the drone a little bit and you would see that all the motor were working
I modeled it myself, but its heavily inspired by the BikeGuy mount and similar flat print style canopies, though its still a work in progress in fine tuning it.
Same here, but the solder blob was on the board and my vtx would shut off after maybe 2 seconds. I took it off the frame, got a toothbrush cleaned the board with alcohol and put it together and it's been going for months with no issue
