Fixing Vibration Issues and Loose Screws on Darwin FPV Baby Ape 2
Vibrating Apart!!!
My drone is having issues with vibrations after one or two days of flying all the screws would be loose and at this point, I have lost 3 or 4 screws, and 2 standoffs. is there any way to fix this problem or is it a skill issue? 😅 I have the Darwin FPV Baby Ape 2.

I've had a BabyApe 2 for a little under two years and have not had that problem. Possibly related to oscillations due to a bad PID tune?
This tune has been super reliable for me in the time I've been using the exact same quad (assuming 6S and analog).

I probably should have mentioned it was 4s😅 do you think it would work the same?

It might, IIRC this was from TorontoFPVs "everything tune" that he normally uses on 4S rigs anyway. Just save a dump of your current settings so you can roll back if it tanks performance

Are the Propellers Bent? easiest way to tell is to look at the drone from the side and rotate the motors. I'd also check to make sure you're motors are properly soldered, and the accelerometer is calibrated in Betaflight. Could also just be a bad motor. I had a similar problem with my Cineape35, Darwin's electronics aren't the most reliable

That also might be it one of the motors is a bit stiff

Ive had m4 nuts vibrate off of matching bolts after being cranked down, simply with small brushed hobby motors. Get some blue loctite and apply it on the threads of your screws, and crank them down. That should hold them in. Or you can go fancy and buy some standoffs with nylock inserts in them, thatd also do it. But yeah darwinfpv is known for being fairly sub par

Ah thank you for your suggestion I will definitely do that when I replace the screws

I'm kinda second guessing my choice of drone now........

Eh, BabyApe 2 is a pretty solid BNF - especially given the price point. Motors are certainly not the best, but I don't think they're the worst out there either. Could be worth maybe looking into upgrades in that regard though . Motor replacement is SUPER easy on that quad as long as you're comfortable w/ extremely basic soldering.

Joshua Bardwell said that his Darwinfpv babyape screws are vibrating out too. I recommend some loctite on the motor screws, frame and stand offs screws too.
