Public Annoucement – SJ4000 from Banggood is screw up


If you got this SKU120425. DO NOT UPDATE the firmware. If you did, download from this guy from this reply and remember to post a thank you.

You’ll get a black screen when turned on and the camera can’t be used. A whole discussion on how screw up the version of these cameras are, are here. I read V1 is newer than V2 somewhere. Where in this Universe is V2 newer than a V1 in anything? Only SJCam.

That’s like WTF! We don’t expect GoPro standard but not firmware screws up. How hard can that be?! Only they know and they seem to know that it’s real hard to be able to screw this up.

It’s either screw ups at SJCam sending old stock to retailers or retailer having keep the stock for so long, now running promotion and getting these cameras out and flooding the market with old cameras. SJCam should and MUST do a recall and stop these cameras from being circulated. Please. That’s the common sense thing to do.

F330 with bigger frame

Was looking at loading more things on the DJI F330 when we were rebuilding the F330 for the 3rd time recently and came across this thread by Theone420. We contacted our local, Singapore workshop and yes, they can do it.

and so, here’s “The Flying Flea”.

We chose to make it in 0.5mm thick ply wood and for fun, an acrylic one.


Weighing it, 74.2grams


As stated in that thread, the DXF comes with 0.9mm screw holes and comes as a guide. You can choose what size you need. We went with the original 2.5mm but the original screws of M2.5 x 6 won’t be long enough. We went with M2.5 x 8.


Draft assembly with the F330 arms.


Weighing it again. 172.8grams with arms.


Size compare with the DJI F330.


The acrylic one.


With lotsa space to mount the ESC within the frame.


Used the DJI Naza M V2 with GPS on this.


Size compare with the DJI F330.


It flew great.
