Thanks, Snow!

I didn’t learn on a sim either. I learned by crashing a lot and breaking a whole bunch of stuff. Starting on a sim probably would have saved me quite a bit of money.

Ok that interesting thanks.
I worked out how to set my mode switch to go angle...horizon...acrotrainer then an override switch goes to full acro. Sounds like that won't actually give me acrotrainer on my new babyape unless I specifically reflash the 4.4 firmware. Because of the onboard elrs Rx issue which I can only bind using non bind phrase mode (power cycle quad 3 times) to my Zorro running elrs 3.3 but with a bind phrase I am a bit underconfident to reflash whilst it's all basically working. Still not sure what the FC firmware target would be as diff all says betaflight 4.4 but board maker matek411

Phot of extra babyape bits. What are they for?

Also it's not clear how far the push on props go on the shafts. I'm a bit worried about pushing too hard on the motord

Looks like they gave you some spare nuts in case you lose some, some spare rubber bands for holding your battery in place, a velcro battery strap in case you don’t want to use a rubber band, and some zip ties in case you need to do some wire routing.

Props should sit flush with the top of the motor.

Just make sure you’re pressing straight down. If you put your index finger on the bottom side of the arm directly below your motor and your thumb on top and just squeeze, you should be okay.

Fair warning, I have stabbed myself in the thumb repeatedly by doing this when the shaft protrudes higher than a prop.

I usually just slightly drill out the main shaft hole and then use bolts to hold the props on, but it looks like those motors do not have standard T-mount hole placement, so you don’t want to do that.

Edit- if things are working, don’t reflash. Just get some flights in. Down the road if you decide you want to reflash, we’ll need to determine what board is in the ELRS version, if it has a built ELRS rx or an external rx, and if an external rx, what rx it is.

Once you finish getting everything setup as you want it, make sure you go into the cli tab and run the “dump” command as well as “diff all”, and save the output to a text file so that you have a backup if anything goes wrong.

Many thanks. We are maiden flying now. Much harder than the sum,,

Awesome! Keep at it, you’ll get the hang of it. Happy flying!

Slight problem...

After many successful flights we decided to add acro mode.
In betaflight changed the ranges on aux2 to allow a switch to go from angle to horizon to acro. Before even test flying this we had just a slightly heavy landing no damage. But then we couldn't rearm and had to remind the Rx! Then we setupbeeper mode which twitches the motors but only 2 twitch and beep. But now we can't arm and start motors either in test mode in bf or live in the field.
What's changed? Aux1 and aux 2 etc all looks the same. In bf setting aux1 to arm comes up with disabled red as usb connected, but no motors start outside of bf. They do respond to beeper.
Any ideas?

Got it going. Changed esc to dshit300

Ok so the Babyape now flies really well in Acro mode. What a superb little drone for the price and for a beginner learnin freestyle!
My question is ... in the event of a slightly hard landing how is it possible to lose the bind between its built in elrs Rx and the Zorro elrs tx? We've had to remind twice. And to do that I can only power cycle the Rx 3 times to get bind mode. I'd like to reflash the FC firmware to BF 4.4.2 now I'm more confident.
In BF Configurator the board is detected as Matek. Can I go ahead so long as I do a cli dump first?

Will that allow me to set the bind phrase that's in the tx?

As long as you do a dump, you can always go back,

I could be wrong, but I’m pretty sure that betaflight v4.4 is the one that started to allow you to enter a bind phrase directly in the receiver tab, using a standard word format, ie: mybindphrase

Another option would be to stay on whatever bf version you are currently on, and use the elrs uid byte generator at the link below:
https://www.expresslrs.org/hardware/spi-...-generator

Put in your bind phrase, and it will spit out some numbers.
Then, use the code below to set your bind phrase in the cli:

set expresslrs_uid = (whatever string of numbers your bind phrase spit out, but remove the parentheses I added to this blurb)
save

Edit- unless your rx is not spi. If’n you’ve got a proper serial (uart) receiver, then you should be able to just connect to it via WiFi and change your bind phrase via the web configurator.

Hmm thanks for that and I'm trying.
Got the string of numbers
In cli I type "set expresslrs_uid = " then my numbers
And it responds set = invalid name

Is this because it's spi not uart Rx?

So I've worked out it is definitely a uart ELRS Rx. I can get it into WiFi mode. And I put the bind phrase in from my phone. Do I just disconnect now?
