Yup, gave it to my son.  He's been flying his emax tinyhawk II freestyle and I've let him have a taste of digital and he leaves his tinyhawk at home now.

I ended up giving it to him (kind of an early Christmas present)

So...  I ended up building an entirely new Tadpole for myself.
   

I used Xing 1303 5000kv motors, 3" props and the kicker here is I decided to try the Mamba F740 mk4 AIO 

It has the ICM42688P gyro.  I know a lot of people avoid that one like the plague but Diatone had this AIO on sale a couple weeks ago and I got it pretty cheap so I'm giving it a whirl.
They advertise it as a FC for a 3" or 4" FC but it's a 40A board and is 6s capable.
Boy, I couldn't imaging this quad on 6s.  The motors are only 4s capable according to iFlight website though.  Might be fun to try out the Mamba Toka 1404 4000kv motor on 6s eventually.

Easy enough to setup but one thing that really has me disappointed is the location of the USB...
It's difficult to see from this photo but it sits right behind the Caddx Vista.
   

Got it finished up last night and got a very short hover in to test it all out.  That's when I found out how annoying the usb location is.  I went to make some PID adjustments and setup my OSD and had to take it all apart again. 

But any rate -got it set up and man does it fly smooth!  Gave it a quick run this morning and then the rain came.  So here I sit looking out the window waiting for the sun to come back out...

Looks great!

I’ll be curious to see your experience with that gyro.

It would require some disassembly and setting changes, but, you could rotate that FC 90 degrees clockwise. Think you’d have a clear shot to the usb port then.

Then I'd be screwed with motor wire length. Unless I solder...  ugh

Yeah, you’d have resolder your motors to the new pads that would be facing them, then change your board orientation in betaflight, and then reorder your motors.

Kind of a pain, not really worth it if you’ve already got everything soldered up and set up, but, something to keep in mind for the next build.

I don’t know what rc link you use, but apparently with ELRS v3 you can change settings in betaflight via WiFi. I haven’t tried it out yet, I’m still on ELRS v2 because I have a couple spi ELRS fc’s.

I'm brandy new to ELRS and I'm using 3.0.1

What is this now???

edit: Found it! This is cool.

Stumbled across this:  https://www.expresslrs.org/3.0/hardware/spi-receivers/

Apply to you?

In case that link below doesn’t jump to the relevant section, the info you want starts around 4:06 (connecting to betaflight configurator over WiFi through an ELRS rx running v3). I think there might be some limitations like a certain chip on your rx, but like I said, I haven’t been able to try it out yet. If you give it a shot, let me know if it’s as awesome as it sounds.



In my case, I have some aio boards with spi receivers, so I’m stuck with ELRS v2.x until betaflight 4.4 comes out.
Edit- maybe there’s a way for me to flash spi rx’s with ELRS v3 without some of the nifty new cool stuff? I dunno, I’m getting confused.

This is also a good solution maybe:

So… are you now connecting to betaflight configurator through WiFi?

I’m gonna be a bit jealous if you are.

Edit- on a fresh new build, I think you still hafta connect to betaflight via usb at least once to set your ports and rx protocol before it’ll work via WiFi, but I’m not 100% sure I’m that.

Be very jealous!!!  This is awesome!  

I was really excited that the usb cable actually powered the rx with this flight controller but that's useless in this situation now.  But the wifi ability trumps that by far!


I doubt you would have to initially setup via usb either.  As long as the rx can enter wifi mode that's all you need.  I ran a little 3s battery down to 9.6 volts getting it working though haha!

So in your case, what is that I was reading about binding SPI receivers to elrsv3???

That sounds so damn cool. On one of my older builds I had a standoff completely blocking the usb port- another intoFPV forum member kindly designed and printed me a hollow square shaped standoff so that I could plug in, but being able to just do it over WiFi? Yeah, I want that.

In my case, I dunno, maybe I’ll jump into the ELRS Discord tonight and ask. If there is a way to make ELRS v3 connect to an ELRS spi rx, I’m all about it even if I lose some features- because then I could still upgrade all of my non spi rx’s and be able to use the new features on those.

As a side note, make sure you’ve got a fan blowing over your boards for airflow anytime you’re powered up on the bench for any decent length of time.

You won't be able to connect via wifi on these SPI units but all the rest you will.

Dude! Thank you!

Now I just gotta decide if I’m brave enough to flash a bf4.4 nightly build onto my spi boards, and if so, then maybe I’ll go on a flashing/updating spree tonight.
…this might take a few drinks.

Brave enough for a nightly build? LOL for some dumb reason that appeals to me. That's part of the fun, figuring shit out like that! I do notice in a lot of your posts, a little liquid encouragement is all you need. cheers to that!

Yeah, I started getting a little more hesitant when bf release candidates started bricking gyros.

But with a few drinks I get a bit more brave.
