hello all!

does anyone have experience with the HM bassline or mob8 or any of their latest mobula offerings that come with an ELRS SPI RX baked into the AIO? i have read these come stock with ELRS V2 and require an upgrade to BF4.4.X in order to have the ELRS SPI RX upgraded to V3 simultaneously. 

i am interested in the bassline to utilize my 2S packs lying around. BUT i would also like to know the kind of gauntlet one has to endure getting this thing to work with my boxer with ELRS V3. is this a straightforward flashing process only of the AIO board and binding phrase affair? 

how about the PID settings during this firmware update? are there presets in BF4.4.1 to ease in setup?

i am also using the dji goggles v1 for this quad. would a foxeer wildfire analog adapter do the trick? as buying another set of analog goggles would be too costly. will the dji goggles with analog adapter provide a better image over conventional box goggles?

cheers!

There are presets in 4.4, at least one of them will probably give you a good tune.

Another option- you can use the firmware at the link below to flash a board with a CRAZYBEEF4SX1280 target and a BMI270 or ICM42688P gyro to a version of bf 4.3.1 that supports ELRS v3. You’ll have to double check, but I believe the board that comes in the Bassline has one of those gyros, but things change so often- I could be wrong.
If you flash to that version of 4.3.1, you’d be able to put the stock diff/dump back in with no problems and have the factory pid tune.

I built a Bassline (just bought the frame, chose my own bits)- it flew great while it lasted, but be aware that the frame is pretty fragile. It can take a hit, but if it hits just right it’s toast.

Foxeer wildfire is a great vrx module, I’ve got one. I’m still analog so I can’t say how it looks on dji googles, but I’ve got no complaints using it with my fat sharks.

Edit- in addition to the Foxeer wildfire, you’ll also need the BDI analog adapter to make them work with dji.

much appreciated sir! i hope the whoop presets are also available in BF4.3.1. will check the link. as for the foxeer wildfire, i am eyeing a seller who posted the complete dji analog bundle so its a pnp affair for me.

thanks again!

latest update on this:

1. the HM bassline is on the way. if it has the default ELRS V2 from the factory, i assume it may also come with BF4.2.X by default right? if i save the dump/diff file for this, is it safe to load it to the AIO after updating to BF4.3.1 which is the hex file in HM’s site. just asking coz i’m migrating to a major version change like 4.3.X to 4.4.X which is taboo with the diff files.

2. i also have the foxeer wildfire module. will this goggle set up be suitable for LR use with a decent patch antenna? if so, any recommendations?

3. if i use this for an analog LR quad, what would be the best analog vtx with range to match the performance of ELRS? 

cheers!

1. It looks like the HM Bassline comes with ELRS v2, which means it will be running betaflight 4.3.x. Definitely save a copy of the dump/diff prior to doing anything else.
To get ELRS v3, you’ll have two options:
-flash the hex file that I linked to earlier in the thread, which is a modified version of betaflight 4.3.x that supports ELRS v3.
If you do this, you can safely load your diff, as you’ll still be on the same major version of bf, 4.3.x. This way you will retain the factory pid tune.
-OR you can install bf 4.4. It’s generally advised to NOT load diffs/dumps between major versions of bf (ie: 4.3 to 4.4). I’d recommend setting it up from scratch. If you want to make your life easier, take screenshots of the ports tab, receiver tab, configuration tab, and vtx tab prior to installing bf 4.4, so that you have a quick reference to get your ports and everything set up quickly. Then try out one of the whoop presets for your tune.

2. I don’t do long range so I can’t advise you much here. Your Foxeer wildfire will work just fine for long range with the right antennas.
Regarding antennas, if you want to go very far, look into triple feed patch antennas, as well as helicals. There’s a variety of YouTube tutorials available to show you how to make a helical out of things like a jar lid.
If you want to go even farther, consider looking into an antenna tracker. Patch antennas and helical antennas are directional, an antenna tracker will turn your antennas towards your quad automagically.

3. Consider one of the newer analog vtx’s that have absolutely ridiculous output levels, like the RushFPV Max Solo (2.5W):

I only just reviewed the Bassline recently and the latest batch actually came with built-in ExpressLRS receiver connected via UART, it's not SPI anymore. So you don't need to flash Betaflight to get it bound to your radio. It's a little buggy though and setup wasn't as smooth as one would hope, as I documented my experience here in more detail: https://oscarliang.com/happymodel-bassli...rst-Flight

the analog setup was otherwise pretty straightforward where i had to update BF4.3.1 to a hex file from happymodel’s website. i bought the analog version for use with the dji goggles v1 with analog adapter. otherwise if it came with a caddx vista variant then i may have considered it.

I believe the analog versions still come with the SPI (X12 AIO), it is only the HD Bassline that gets the upgraded CrazyF411 that comes with Serial ELRS probably because of the beefier voltage regulator (the AIO is also 2-4S capable and comes with 20A ESCs). If they eventually release an HD Mob8 it will probably get the upgraded board as well.

hello again to all analog users!

i have finally gotten the analog bassline up and flying and i would like to get the very best performance from this analog system. some say the image quality on the dji goggles v1 thru the analog adapter is limited by the quality of the fpv camera which in this case is the Caddx Ant 1200TVL. is there a suitable drop-in upgrade i may consider down the road which could help improve image quality?

i would not expect this to meet digital standards but i would like to hope analog can still habe more to offer.

The Foxeer Toothless 2 is my favorite analog cam, and it’s available in a nano size.

It may not be a straight “drop in”, you may need to swap the cam plug.

To give you an idea of the image quality of a Foxeer Toothless 2 Nano, I’m using one in the flight video below. The breakup and snow/speckles that you see half the time is because of where I sit when I fly- under my carport, in front of a cinder block shop, with my house with steel siding to the left of me.

It was was recorded on the crappy built in dvr in my Fatsharks, the actual video through the goggles looks better.

i have heard about the so-so fatshark dvr performance. otherwise the colors and clarity look decent despite the less than ideal position from which you shot this video.

Three weeks ago I ordered a Mobula8 ELRS SPI analog (not the bassline). It came with BF 4.4 baked in, which includes ELRS 3. I did not need to flash it. It bound to my ELRS 3 transmitter right away. It is a great drone. With RDQ 525 mAh 2S I can get 10 minutes of flight time in easy flight outdoors.

On November 16 Happy Model announced a new version of the Mobula8 with a serial uart receiver. Now we're talking.

You need to change the plug, and remember it's not red to red, black to black and yellow to yellow, Foxeer and Caddx have the cables in a different order.
Though the first thing I would check is if the Toothless fits.

I have changed cams in a couple of quads that came with the eos2 nano cam and used Foxeer Toothless nano or Razor nano IF IT FITS, which it does not always do because it's a few mm longer than the eos2 or Caddx Ant on both the front and aft side of the cam mounting screws the angle of the cam may be restricted by the cam touching something. If that's the case the Ant is soooo much better then the eos2!

I have the Happymodel Bassline Walksnail edition - It's the most fun Quad in my fleet, 2S 2 inch micros are magic.

The Walksnail version came with the older F411 AIO, as I needed ELRS 3 so I immediately flashed the latest 4.4 version, and I can say that the latest BF4.4 is compatible with the F411 AIO that is in my Bassline. Before I started I did grad Betafight Dumps and cli backups, but I didn't use them. I did grab screen shots, of the different tabs, config, PID turning, and kept those for reference, and compare my own tuning efforts as with Betaflight defaults, as a starting point.

I have also created a video as with the physical tuning of Bassline, as I considered the BNF build quality from Happymodel as poor, and hopefully they pick up on the QA in the future, as Happymodel make great Micros and whoops.
