SIGH....................   Just when I think I have got a sorted working HDZero system.......................

Flying the Mob 6 today

Firstly it twice does the "seconds into flight full rainbow pixel screen" followed a few seconds later by the "black screen OSD only" trick again.

Then after a couple of tries at rebooting (changing battery for no good reason) and the seconds of flight to rainbow repeat again, it stabilised, and I had a decent flight around the house.

Changed battery, flew again, flying well on a second circuit I just lightly clipped a wall on a turn and it dived a foot or so onto carpet, and went black screen with OSD.

Reboot, and the image is good, but inverted..................  

Tried all external actions, check connections, change battery, same.  Turn off, leave for a couple of minutes, power up.........lovely image..........inverted............. 

Leave five mins, reconnect............ image inverted...............  

Checked with goggles and screen, also another quad, so its the Mob6 and presumably camera since OSD is OK.

NOW what?

Did you try with a different mipi cable? Also did you check the ports on vtx and camera to make sure no pins are damaged or bent?

Don't have a different mipi cable to try, mipi cable has never been off nor disturbed. Looks fully home as its always done. Quad hit on one duct and fell to carpet right way up. No chance of direct hit to mipi nor connectorsin the touch it had, so any issue stems from assembly.

I was expecting to find a command to invert the image, seems not.

I have just been flying it around LOS with screen on while observing and the screen image is good, NO visual issues, other than its inverted! Gave it a few bumps into walls and not a flicker from video, its perfect......... inverted.

Whatever caused it to invert seems hard on.

Did you look in the goggles menu or in the camera settings for an option to flip the image? It's in the camera settings so if you didn't try that you need to go into those settings using stick commands which you can find in Oscar's article at the link below. You should find an "HV Flip" option somewhere in there. Why it suddenly changed of its own accord though is a mystery.

https://oscarliang.com/setup-hdzero/#Stick-Commands

The line in the Camera menu for HV Flip has no entry to change between the left and right arrowheads, just a blank. I can effect change on other options, but that one does nothing.

Info states the camera is a Micro v2. It was standard fit on a BNF Mobula 6 ELRS HDZero.

Maybe there's a CLI command to force it, but it does not look as though its a user menu changeable option.

Well, here is a thought.. I all else fails i there space to physically rotate the camera?

Yes, there is, I had checked, I'd take about 15 minutes......luckily the Mipi is OK for length and the camera mounts central on its sides...........  but you know that the day after you do it, it'll revert itself and put you back to square one!

Another likely way would be to re-flash (and so in theory reset) the firmware. Same applies though, it could flip again.  I have asked HDZ for info, viz:

Does this camera normally allow inversion on menu?

Is there a passthrough CLI command to force inversion?

etc..........

When time zones align, no doubt they'll reply

Giotta love them Crazybees . . . 

Oh . . . wait . . . no you don't . . .

Guaranteed it'll happen to someone else, and yea . . . I keep going back to them . . . ow, I hit my head . . .

Not tonight, Horatio     

The VTX (and of course Camera) is a completely separate product, separate board. HDZero Whoop Lite (with the optional covers removed).

Its unlikely (?)  the Crazybee FC board since the OSD is still the right way up!

Every time I look in my Dead Crazybee Box, I really think anything that comes within a couple feet of a Crazybee could be in trouble . . . 

I thought it ran through the onboard vTx like the M6 & the other Crazybee with the 400mW on board . . . I haven't played with that spensive stuff with my Whoops, and probably be a while before I do.

It took a while, but I pretty much take replacing parts & pieces on these things as the price to play the game. If I go for a tumble & trash my analog vTx & camera, saving the antenna, my most expensive setup is about $45. If one of those digi setups catches a cold, it costs more than that to cure . . . that's a bit too much for me.

All what you're into, and I do like seeing other peoples HD vids. I've had the HD setup from my M6, HD DVR & cam/canopy in a jar for over two years and haven't put it in anything else yet.

I cracked up this morning and inverted the camera.    

Several successful flights later............. 

Its set to only 25mW, but the current drawn is RIGHT on the limit for the batteries once they lose their first newness. An example, several 380 cells that have done maybe a max of 10 flights will allow the VTX/FC to trip if there's a current surge in flight like clipping a wall or gate (angle mode) and turn off the video. Only power cycling gets that back, so its the walk of shame every time.    

Once beyond say half flight duration sub 3.5v under load they can sag to trip the video just with suddenly opened throttle.  

Some newer only 1-2 flight 300 cells work without that tripping occurring, though the lower capacity obviously limits flight time........ but they DON'T allow the video to trip out for what would be an expected but shorter (too short for my liking) duration.

The combination of the crazybee FC and the HDZero Whoop Lite really does push 65 fittable batteries to their limit and beyond at the slightest provocation. A bridge too far it seems, shame as the quad flies REALLY well when its not shutting itself down.

As a test I have put the same batteries once tripping the HDZero video on the Mob6 Analogues and flown them for at least a couple of minutes more beyond that.

SO.............I am going to transfer the 65 hardware over to a 75 frame where I can run a larger more current capable 450 or 650 battery!

Yeah, unfortunately I think a digital VTX on a 65mm whoop is pushing things just a little too far unless you want to be spending more time swapping over batteries than actually flying the thing. Before purchasing the HDZero goggles I was considering getting one of these or the Moblite7 and then all this talk started blowing up. Now it is completely off the table and I think I will just stick to analogue for tiny whoops. I would even say that 75mm is on the edge of some limitations for flying a digital VTX. I saw it mentioned somewhere that 85mm is probably the smallest you should really go with for digital quads so maybe I will put my Whoop Lite VTX in something of that size. Obviously those are a little too large for flying around inside a house, but I personally don't fly indoors anyway.

I have two of them and have not had any issue besides I can't run any BF higher than 4.2.11, which isn't a big thing in the grand scheme.  But then the same for the BetaFPV boards that everyone hates.  No problems at all with any of them, aside from a defective Meteor65 I bought (I knew it was defective before I bought it and it was basically a full Meteor65 for £30) that someone had flashed RC6 to and bricked the gyro (new £35 5A BetaFPV AIO FC and it was airborne once again).

Saying that I am young in this hobby, less than a year.  I was schooled by all you guys when I started, have watched 1000s of YT vids on FPV related stuff, hacked on BF a bit and built two quads. I kind of know enough to not get into trouble very much.

On the power thing, could you do a 2S 75mm (I think 2S on a 65 is going to be too OP) whoop, but set the throttle limit to 50-60% to get something that flies more like a 1S, but has the extra juice to power the HDZ system and increase flight times?

Having DJI, I only went HDZero FOR the tiny stuff and a better image.

The Mob6 HDZero is plenty powerful and agile enough, its really good to fly around the house, BUT:-

1. You are back as the first Inductrix was with short flight times. 
2. It punishes the cells, which are running close to the edge of load sag and shutting down the video.  SO, clip something in Angle, get the typical four motor current surge from that, and you can be (will be when 1/2 way or more through a flight) suddenly sans an image. Its particularly unacceptable as it does not self recover, requiring a power cycle.  Obviously acro reduces that tendency!


The MobLITE7 is if anything too lively, its SO throttle sensitive its uncomfortable and always trying to get away from you. Great for flat out flying with the required space, not so nice for fast cruising in tight spaces. Give it an open race type course and its fun, but despite trying all ways I know to tune it down, its combination of ultra lightweight and grunty motors gives a hard time.  Its similar to a 450 Heli, another design that is too small for outdoors, yet too large for even decent sized sports halls unless you just hang on the rotor head, and no fun AT ALL anywhere smaller.

Even weighting the Moblite7 with 650mAh cells to tame it, throttle limits, expo, etc, its right on the ragged edge of being too responsive in throttle.

I already have an analogue 75 that I built with basically a 65 set of gear (Trashcan frame, Mob6 gear) and that is fast, agile, but MUCH more comfortable to fly, its not trying to bite you all the time. I was going to put HDZero on it, but it'll now stay analogue.

However, I'm now def going to transfer the Mob6 hardware inc HDZero onto a Meteor 75 frame as I have a few new unused to use.  I'll report outcome!

SO, my working indoor round house and garden hangar will be:-

My two analogue Mob6 (one of each 19000 and 25000kv) as they can be thrashed around with impunity and are much more fun despite the poorer image.

The analogue 75 hybrid, and soon the HDZero hybrid 65/75.

I can fly the Foxeer CineWhoop 25 fast round the house, had a few sessions now, but I live in fear of the pusher props snagging the upholstery, and its ruddy noisy!!


Shame though, as the better HD image IS wonderful and a great assist to accurate very tight to terrain flying.


Maybe the next gen efforts will make it practical.

Probably ½ of the box was when those 1-2S Crazybees first came out & QC was terrible, the rest in the next three flavors make up the other ½ of the box, with 5 outta 5 of the BetaFPV boards in there too They're really not contagious, but with so many, I worried about a curse . . . I will give HM credit though, they replaced every one of my defective boards, and in general have been decent in the last few years, still a couple flakes, but that's a huge improvement.

My 1-2S Mobula, in my house with my layout, on 1S it has more than enough power to get in trouble, and have no need, and never have run it on 2S inside. As for flight times, I get the same flight times on 1 & 2S, just the more power on 2S. My bigger Whoops all get the same flight times on 2 & 3S, so I don't think the cell count adds anything to flight times, but I could be wrong . . .

½ throttle would tame it back down to a point, and the 2S would have the extra torque & power to hopefully make up for the weight of the HD stuff, and would be great if you can squeeze some extra air time from it. The original Mobula HD had 1102/10,00s & was switched to 9,000s, and said 2S for inside & 3S for outside, and that was for the weight of their HD stuff. 

I made a 1-2S Mobula 6 a while before HM . . . 8^} . . . and on 2S, was a little pocket rocket, and really fast, but heavy feeling & flying too. It was like throwing a hardball really fast vs throwing a tennis ball really fast. I could really feel the weight, especially going into turns. Those little 31mm props do not like weight . . . the HD stuff on the 65, plus the double batts would be a tiny cement block flying around.
