Going F3 to F4 - 20 x 20 stacks

[Futuramille]

I gave up on the old pico blx in my newly rebuilt cerberus micro. im eyeing the new Furious pico f4 for both my 2" and 3" Cerberus.
20 x 20 stacks on both, the two inch has a fresh cicada 25a 4in1, new brother motors but try as i can test, this older pico blx f3 fc on the 2" is suspect. motor one doesn't show in blheli (same as before the rebuild), tests fine in BF with multishot but not dshot (dshot capable) and now RX isn't showing in betaflight. ive tried everything i can think of... hours of videos. bad fc?

Also, ive still got the 3" to rebuild. I need a new 4in1 and FC in that to (full rebuild) . i was considering an AIO board (space) but...
if y'all wanted to get the best 2s to 4s capable 20 x 20 stack with F4 capabilities... what would you get? ill try to use the same stack for both with just a motor difference if bossible. these motors..
im thinking this..
FuriousFPV PIKO F4 16MB Black Box Flight Controller, FURIOUS FPV
and the cicada 25a 4in1 for both... Cicada 25A 4in1 BLHeli-S DSHOT 2-4S ESC (20×20) – Flynoceros

thoughts?

I like this ESC below. Really beefy build quality with lots of big caps. They also have a 32 bit version.

The flight controllers there are also very good. They have a bunch of f4 options, like this one that connect to the FC with just one ez-cable. I used an FC and ESC from them on my UL4.

i like beafy, good price there too. do you think it's better than a cicada 4in1? .. and for the sake of conversation, in what way?

I'm wanting to compare best to best but with my little experience with different options (just now wearing out first quads) im taking a hesitant stance. im checking options. thanks for your input as ever Green!

I have a cicada 10A in my 1104 Predator X, never had an issue. The Ori just looks and feels like premium quality to me. I am a sucker, the thick PCB and big caps get me every time bwahahaha

 

[Futuramille]

my thought/goal is to have a 2 - 4s system on both and just run 2-3s on the micro and 3-4s on the mini.
do y'all think this is possible?
eg: max the stack on the 3"... copy to the 2" and have exactly the same hardware, betaflight, blhelli, OSD( frsky mx+ rx) etc.

im thinking, same same would streamline maintaining these smaller quads... or i end up just flying the 5" cerb v2 and missing out on the smaller airspace.

Yes the ESC will be slightly overkill for the smaller motors but it won't hurt anything other than your pocket book.

the cicada 25a 4in1 is actually what's already on the 2" cerb. im just hoping the same esc works on the 3".
getting the flight controller the same and .. going from F3 to F4 in both is the challenge.

 

[theGreenOrange]

That should be fine, I use 1407-3600k on 4 inch props with that 20A (Ori) micro stack. Cicada seems like a pretty good line so it should be no problem.

My best advice is to find components that work for you and stick with them or you spend lots of time fiddling with stuff

i kinda have all furious fpv boards.
on the other hand, this raceflight revolt setup is still working flawlessly.. i just don't know raceflight and simply need to figure it out to reduce D a bit before installing new motors. i wore out the motors.. over 1300 packs and counting.
and if i could figure out how to get the micro setup/ rewired.. maybe?

"this older pico blx f3 fc on the 2" is suspect. motor one doesn't show in blheli (same as before the rebuild), tests fine in BF with multishot but not dshot (dshot capable)"

has anyone seen this before.. BLheli shows only 3 of four motors (missing #1) and Betaflight controls all four motors when using single/ multi but motor one doesn't work with Dshot though 2, 3, 4 work perfectly.

 

[theGreenOrange]

I had that before but it was on an FC that didn't officially support Dshot. The fix was to move the bad motor signal wire over to the LED pin. Even though the cause may be different, the solution could work for you.

Using CLI resource command, you could re-map the motor pad resource to an available DMA capable pad (like LED pad if not in use). Then you can either move the troublesome ESC signal wire to the LED pad, or solder a jumper wire from the current motor signal pad to the LED pad.

... something i haven't tried!! resigning the uart.. in fact (though i can't find the photo yet) the pico board was originally grounded differently and signal was on uart 2? i need the picture sigh. the board may have had an issue when built bnf from flynocerous. in my ignorance i rebuilt it without tracking how it was initially setup because i want getting battery voltage in OSD and it looked funky. i desoldered it and.. sigh. so that's why I'm thinking start over on the 2" build.
the 3" jyst needs new motors, and learning raceflight to fly well again. i have new printed parts and its flew beastly yesterday but two motors are "stuttering" randomly... the magnets are layered in a cooked sheen of playing the part of weed eater.
the cheap path is replace the motors (add paracord) and stick with what works. the only gain is standardization. maybe i should wait.. we have raceflight gurus on the forum. i was also looking at some of raceflights stack options for the 2" do they run betaflight withough issue?
