Sp racing not armimg. Betaflight 3.3. Devo 7E

[Cartman9090]

I am new to this! What is to be checked? Armimg not reacting on stick.

 

[mozquito1]

Do all the motors turn in the motors tab if you slide the master up & lipo in.
Did you flash the esc firmware & match the end points up to match min & max in BF. The video was jerky & I'm on my phone, basic but are the tx/rx bound?
What protocol are the esc's & does it match what is checked on the configuration tab. Top right.
Are you getting input on the receiver tab in BF?. Have you set modes up properly & set the Aux switches for arming & modes on the radio Tx itself.
Do your motors move in motors tab in correct order. If so then it's settings on the fcb, if not it will be the esc's.
I forgot my old littlebee only have 1shot125 but I clicked multishot as normal & I got exactly what is happening to you now. But the few things above can cause this.

Can't you put the arm on a stick.
How many channels rx do you have ?
In modes tab in BF click arm, move the range slider to 1500 & other @2000.
And then check the box next to it as Aux1
Pick a 2 position switch on the Tx. I use swa on mine. Then in the tx menu assign Aux1 to the 2 position switch of choice.
Same with modes,angle & horizon go on Aux2 which is a 3 position switch. Acro mode is the 3rd click. It not listed, it's just a given. If you don't set up angle or horizon then all 3 ranges of the switch will be acro mode.

Now it looks like this. Arming ok( I think ). But the drone is crazy when carefully initiating throttle. Spinning aggressive and flips over....

All motors move when sliding in betaflight. But I am not sure if I am using correct esc model, if that matters. I did study the correct propeller mount, but I am not 100% sure...

Tazmanian Devil Effect. (That's an actual betaflight term now) Board orientation wrong, motor direction wrong or props on wrong

 

[Cartman9090]

Props seem to follow the arrow on the engines

Checked the orientation and the props direction, seems ok. The devil seems to be present... Other tips? Try downgrade fw?

The engines dont spin uncontrolled when props are off....

I checked the engines and props direction. All run correct according to the sliders when testing in BF.
It seems all the channels correspond correctly in the receivers view in bf. I did not specify any max value, is that important? Only set throttle minimum. I did adjust some values inside the walkera radio, pretty much random since I am learning and trying. But seems to correspond within betaflight.

I dont know if I am using correct channels for arming and flying mode. Is that important? It seems to arm.

Is this behaviour connected to some kind of automatic protection caused by some hw fault or improper setting?

The esc electronic I dont know, I chose random type in Bf.

It could just be that you have to be a bit more gentle on the stick.
But in blheli you will notice there is a minimum throttle command on a slider for each esc & a maximum.
For my own reasons I have mine @
Min = 1020
Max = 1980

Then in BF config I have
Min = 1005
Mid = 1500
Max = 1980

And my mid stick is @ 50. Have you altered this on yours. If it's on or around 30 then this would have the effect you are having. Someone else had this same problem on here not so long ago. It may be worth looking @ thread post going back a month or so.

I am very gentle on the throttle!

Downgraded the fw but even worse. Now it did really take off without control!

Is there such a difference on throttle minimum 988 ~ 1010?

 

[mozquito1]

988is low should be as close to 1000 as you can. As the esc's are tied in with this.
I still use multishot which relies on the clocks. If one esc range peaks @ 1989 another @ 1992 & another @ 1995 & last one & 2000 then set the range to just below the lowest so all motors will peak with the same speed. Dshot doesn't use clocks but I think you still have to set the range. I'm in work @ the moment but when I get time I'll look back & see if I can find the thread & see if they resolved it.

Yeah - the difference is 22 (sorry for the dad joke).

You may want to check out Painless360 on YouTube - he has a video - I think in one of his beginner build series' that talks about good practice on setting input min/maxes and why. I think Joshua Bardwell may have one too, don't remember.

 

[Cartman9090]

Haha
Is ok I got some to learn.

Like now, the props cut my arm bloody and broke. Need new props, how do I choose correct ones ( pitch , blades etc ? )

I have this esc (and this engine)

Seems I should use Dshot 150/300?

 

[mozquito1]

Prop's I use @ moment on that size motor
Dal cyclone V2 5040-45 tri blade
King Kong tri-blades
Emax avant dual & tri blade

I think the Dal are the best.
Im going to try some gemfan over the summer.

I'll see if I find that prop!

Now i found why downgrade fw nearly killed me. The latest version 3.3 sp racing has implemented security for problem like a have - uncontrolled at take-off. Thetefore it just flipped when started with that fw. No harm.

When i tried earlier fw the drone cut me and luckily it pulled battery power .

Now I adjusted sticks to what you Said. Throttle 999 at lowest.

But i really can't tell if problem solved . is hard to say for a newbie by holding the drone running without props! Need wait for new ones.

 

[RENOV8R]

That feature you are talking about is called antitaz (protection against the Tazmanian Devil effect) I'll say it again, 99% sure it's improper board orientation. There's a tiny arrow on your flight controller, which way is it pointing?

I calibrated esc's now, wasnt familiar with the prodedure maxing the Main motor slider and then connecting the battery. Seems like that made a difference but need wait for props. But should I do something to any software om esc's, and how do I do that?

What does "board orientation" really mean. I am not familiar with this. I understand directions, but if you mean the fc it has already been mounted and confirmed working at the previous owner.

When holding the drone in my hand and looking at the animated drone in bf, the animation flips right when I turn my drone left. And so on.
At the same time my sticks seem to be correct directed due to the bars in the receivers tab in bf.

Like this:

Right stick right (Roll) moves to 1841 (Middle 1500) Right stick Left move to 1159

Right stick (Pitch) down at 1159. Middle 1500. Right stick up at 1841.

Left stick down (Throttle) 999. Throttle Max 2001 .

Left stick Right (Yaw) move to 1841. Left stick left move to 1159

 

[RENOV8R]

All your endpoints except throttle need to be adjusted so that low is 1000 and high is 2000. Can you please post a pic of your flight controller from above looking straight down.

I have these esc's..does that bind a specific protocol?

I chose multishot.

Need learn about these protocols.

I will adjust all sticks in receivers tab bf to min 1000~max 2000 then. Throttle is min 999, max2001
