Quad goes crazy on lift off

Secondly, do you have a suggestion to fix it? Top is right, right is bottom, bottom is left and left is top. I don't really know how else to change the orientation. I've been scouring the internet to piece things together since all of the parts are new to me and I'm never sure where the problem could be. (Transmitter, quad, settings)
Thirdly, does AETR1234 mean Mode 1 and TAER1234, Mode 2?

On your flight controller there should be an arrow printed on the board. (Telling us which flight controller you have would be a big help). The arrow should point towards the front of the quad. If it points to the left instead, then all you should need to correct is Yaw, -90 degrees (or +270). Some photographs of what you have and how you have put it all together would really help.

The order that your radio sends the channels has nothing to do with what mode the sticks are.

The ordering stands for Throttle, Aileron, Elevator, Rudder, aux1, aux2, aux3, aux4

If you move your throttle and the configurator shows the roll(Aileron) channel moving and that's the first thing in the list, then it says your channels actually start with the throttle as the first one.

I know it can be daunting at the start, but if you are structured and take things one step at a time, you'll soon be in the air!

I'm already getting more usefull info here than by trying to look around online.

I'm using the nighthawk pro 200 for now. (I have my own build ready to be put together, but thought this would get me in the air faster)
So I don't know how the board is put in. I opened it once to add the receiver, but it's all so packed that I'd rather leave it closed for now.
Specs are: 
- Camera:CCD 600TVL

- Flight controller: SP Racing F3 ACRO
- Motor: RS2205 2300KV CW THREAD
- ESC Lightning_S 25A (BLHeli_S)
- Flight weight (g) 370g (Not including battery)
- Antenna/VTX 25-200mw

Edit: If I leave my roll on 180 and remove the yaw I should be able to check if the flight controller is put in upside down?
I might just have to fix the ordering now. I'll try that when I get home and test flight it without props inside the betaflight program. (Would it freak out in betaflight like it does in real life if something is wrong?) If it still isn't working and I'm out of idea's I'll just record my pc going through things while saying what I'm doing/touching.

I checked the quad for damage and only the ground wire of the battery connector was damaged (From what I see). Maybe that smelled like something burning for a second. (Red wire is still fully surrounded by rubber.)

Here's the top side of the SP Racing F3 flight controller from the manual:

   

As you can see, if it was mounted with the arrow pointing forwards, the USB connector would be at the rear. If your USB is on the right, and is still on the top of the board, then the only correction needed is Yaw -90. If it's on the left, Yaw 90.

Awesome. It is indeed to the left. So I'll check if it is on the top or bottom. If it is on the bottom the roll 180 is also correct?

If it's upside down, pitch 180 is what you need.

The 3D model in the configurator will confirm when you have the settings correct. It should duplicate the movement of the quad in pitch, roll and yaw axes.

Because it seems a couple of folks had to work on this I figured I'd write a very basic tutorial on how to validate these settings.

hopefully it helps... I know it's very basic but if someone trips over this thread and is confused about where the 3d model is it might be useful Smile

It's upside down apparently, but I tried pitch, but roll seemed to fix it in de program. So I went outside because in the end it's the only way to test it. I was so scared after the first fiasco. It flew just fine. I'll have to fiddle with it a little to adjust the sensitivity. It's probably a bit too sensitive, but I'll try to go to a big field with a laptop before I start messing with that stuff.
Thanks for the help. Just knowing about the existence of certain options makes it all a little easier.

With Pitch @180, the front of the board is thought to be in the rear now. With Roll @180 the front is still facing front.
Hope that clarifies a bit.

So changing pitch would have meant Yaw would have to be at 180 in stead of 90. If I understand correctly.

It's probably easier to visualise this if you take a business card, mark an arrow and a USB connector on it and hold it horizontally in your hand with the arrow on the upper surface and pointing away from you.

This is how the flight controller's firmware expects the board to be fitted inside the craft and is considered as zero rotation on any axis.

Yaw is rotation in the horizontal plane around the centre of the card. Pitch is rotation in the plane that the front and rear of the card lies along and roll is rotation around the plane that the left and right sides of the card lie along. Positive rotation happens in a clockwise direction and negative rotation in the counter clockwise direction.

So, if the board is upright, but the arrow is pointing to the left or the right, that's a 90 degree rotation in either direction on the yaw axis. If the board is upside down, so that the arrow is on the bottom, then if you rotate 180 degrees on the pitch axis to correct that, you would also need to rotate 180 degrees on the yaw axis as the arrow would now be pointing backwards.

The important thing to remember is that the transformation is relative to the default orientation of the board.

No, yaw is left alone. Unless it is "pitched" upside down and turned/yawed 180, but then that is the same as if you just roll-180

Make sense?  Huh If not I can make a super quick video for you Wink

Glad you got it going!

If it feels "sensitive" try turning down your RC Rates down a little.

Yeah, I haven't gotten any real flight time with it because I didn't have time tonight, but I'm looking into how to do that. I use DRL simulator, but I can't find the rates as easily in betaflight, so I have some googling to do, to figure out where to adjust and what numbers are usable.

The rates are located under the PID tuning tab in Betaflight. They are to the right of the PID values, listed as "RC Rate" and "SuperRate". You can decrease these values to make the quad less sensitive. The numbers are a personal preference, but I would suggest halving the rotation speed to start with. you can always bump them up if you find them too low, afterwards.

To see where you have them set, the column "Max Vel" is the rotation speed in degrees per second. Use this as your reference, as the rate parameters are not linear (halving RC Rate won't halve rotation speed).

I would take a different approach... 

I would make sure my Max Vel matched my rates in DLR... So if in DRL you're running something like 500 degrees, your Max Vel in betaflight should match your Max Vel. I think for a new pilot having the simulator and quad match as close as possible is critical. 

However, if after that it still feels too "sensitive" I'd say try upping expo a little (note the emphasis... you likely wont need as much expo as you use in DRL since current betaflight versions already have a curve to stick responses).
