It overcompensated massively.
P must be lowered quite much.
I plan to test on my EZ Hawk but haven't done it yet.

That most likely explains what mine did...servos was twitching a lot

UndCon

Cool - I have not had the time to tinker with my Swift II so much as I would like.

I did some tests and it seemed to act as supposed to, but I think it was very sensitive to inputs making servos work a lot (over reacting)

Some flights with my Quadcopter

UndCon

I think it can be used 2 ways

1st is a failsafe to avoid *Copter runaways
2nd is a auto landing feature - engage by radio or simply turn your radio off...
Baro helps of course...

either way I understand jevermeister's problem...

motor - desired value = cool descent

UndCon

about gliding...

Cool idea! - I might give this a try on a future *Copter I also like my floor hockey balls as the rounded shape has built in give in the design. I was thinking of adding a spring steel wire bent in a big loop that should give about 5cm of cushion. The problem I see is that it is very rarely I put do...

HI!
I did not have time to test this yet'

//UndCon

UndCon

I think it would as you run motors at almost constant speed...

UndCon

4 motors and 4 servos = Quad vario pitch

Imagine all 3dflights...

UndCon

Now I think my wing is ready for a test

Small adjustments have been made and now I must get the code running properly, my test-rig only allows 5 channels

UndCon

I also bought that radio - and FRsky DIY module and added a ton of hacks

That is a really good idea. A G-logger

UndCon

Cool - I downloaded Hamburgers dev

Ill update Output.pde and try again

1st I must try Hamburgers code - then Ill continue to next part.
//UndCon

UndCon

This is really good - I wanted to go for this setup a while ago but I decided not to as it requires a camera operator and 2 FPV systems.

UndCon

I think I have turtoise svn - at least I used to...

HI Hamburger!

I used a fresh copy of 1.8 - Ill see if I can find your modified code.
If I only knew how to get the files...do I really have to download them 1 by 1?

In my test on the desk it seems like YAW and PITCH are swapped in code (unmodified 1.8) ELEVATOR When I pull up YAW value goes down When I pull stick forward YAW goes back up RUDDER left turn = PITCH value goes UP as well as LEFT & RIGHT servo bars right turn = PITCH value goes down as well as L...

UndCon

I tried to connect the board and servos went crazy A few things comes to my mind... There is no motor support in flying wing code. Does all channels still have to go into the Arduino? Rudder is needed to start. ailerons/elevators is needed to steer the wing. I also want Auto level ON/OFF on my gear ...

UndCon

My wing is maidened and ready to fly

This wing will be equipped with FPV gear when I get my camera but until then I can play with some MultiWii on board.

UndCon

My goals is 4 wingservos

2 ailerons and 2 flaps

UndCon

The original problem of course - why I could not turn off motors with the usual stick input. I felt like your way to solve it was - "buy a new motor if you crash" but I want to save the gear (mainly 'coz it takes ages fr HK to restock motors) I intend to go FPV with my quad. If I crash in ...

UndCon

No apologies needed - no offence taken. I was just surprised about your approach to the problem. I will try my Quad once more now that I repaired/replaced the broken motor - but I will have to try with a different prop, 10*4.7 instead of 10*4.5 I know since before that you can have different props w...

relay? another point of failure? and to throw a switch that triggered a relay that effectively cut the battery off, that was powering a receiver, that was triggering a relay, which was powered from the same battery? so who's going to power it then? I think all of that it's a bit of over-thinking......

UndCon

Hello! The idea of using fuses was also on my mind but as a secondary solution. 1 fuse / ESC is enough and should be relatively easy to implement into existing designs. I have center plates from Flyduino and would like to see a redesign of the boards allowing fuses to be used - or bypassed depending...

UndCon

I am using minthrottle at lowest possible turning rate What good is motor stop if main loop crashed? My way to solve this is outside the arduino code - so you can always turn off your motors no matter what. A remote switch, a relay and you are done - no big deal. Obviously my motors got more speed t...

UndCon

Yesterday I went out for some fun flying with my Quadcopter and managed to destroy a motor and I bent an arm slightly. The Quadcopter landed upside down on grass and I was not able to turn off motors from radio. The crash was my own fault trying to flip a few times - but my RC-rate was to low(loop w...

Another V4 board owner...I added BMP085 to LC (just like your picture) and AXL345 instead of NK

Seems OK in GUI

UndCon

Hello!

What are the current status (running1.8)
Alt hold is implemented and perfected?

I added my BMP085 to a Paris board
(bought long time ago but never got to use it)

I also added AXL345 instead of NK and will see how the outcome is...
(Backup NK is ready for a transplant if necessary)

//UndCon

UndCon

On V4 you have power in marked BEC

UndCon

I would not recommend this at all!

Possible yes - but at the cost of main loop in program being even slower - are you willing to take the risk?
There has been hours upon hours put in the code to get it running as fast as possible and you want to do the opposite...

//UndCon

UndCon

Cool - a MSComposit Swift II is heading my way.

I will try the new code as well...

UndCon

Cool - good work/coding.

If AUX2 will be available for promini it also means all my shields will be outdated as they does not have headers for AUX2.

No big deal but the extra feature could be nice to have. (and I will on my MEGA1280 instead)

//UndCon

UndCon

When I get back home from my vacation I will get a Swift for FPV use and I will try this with the Flying Wing mode.
I will also try the airplane mode in my Skywalker and see what happens

//UndCon

UndCon

Cool 1.8!

I have been waiting for this release.

GJ all involved
//UndCon

UndCon

Good work and inestigation!

I have not yet connected the BMP085 I have @home - but if this issue gets sorted I might give it a go.

//UndCon

UndCon

Yes - changing + and - should invert signals.
Just like its done on other flightmodes and you can read in comment
//UndCon

UndCon

Good job P!

UndCon

I agree on that one Alex. I had lots of trouble trying to get servo running on motor pins.
Using A0 and A1 was easier.

//UndCon

UndCon

Yes it is.
My code is almost done and the only problem I have is to reduce the communication to servos.
(I'm using motor pins for this)

Everything else is done...
//UndCon

UndCon

Cool - how did u solve the update to servo?

I didnt manage that...

I did not want to use A0/A1 as I intend to keep camera stabilization..

UndCon

value should be 1500

1500 is center in PWM world of 1000-2000

UndCon

HI! I am aware of ardupilot - but my ideas is to use the current MultiWii and sensors (cheap platform) for this.

To learn more about this I am currently programming a "servo multi mode feature"
It is clear that my problem is the communication on motor outputs that I have to lower...

UndCon

Sounds interesting for FPV/Video use as the default autolevel is very fast to gain control again

UndCon

Hello!

Thanks for your help.

I'm not sure what you are doing here (or me

)

I added pins like yours in multiwii.pde

Pinmode PortB high, low etc for all corresponding features.

I'm not sure about the rest of your post...

UndCon

Darn!

It looks good in GUi but does not work when I connect servos.

How do I convert motor outputs to servo outputs?

If I connect a servo to the motor pins it gets very nervous

Compare that to the servos connected to stabilize camera
(I want more controls smooth like camera)

UndCon

I think I got it sorted! I would like to hook this up to my indoor foamie but I'm not sure it can handle the extra 24grams of my test-rig. 1st test is Easystar mode (elevator/rudder) 2nd test is Skywalker mode(elevator/rudder/aileron) I have 1 servo on the foamie but the code for Skywalker has 2 ail...

Hi!

Sorry for being off for some time. Now I have some time where I can play with this gear again.
(my vacation starts in august)

Hopefully I can sort a few things out during the day.
//UndCon

I dont think it works with my Spektrum gear...but not tested yet

UndCon

Seems to work as 32bit application - II only tried to start 64bit...

Now I got 32/64 of Win/Lin/Mac

Still some issues in code...and I will mount the board to my Indoor Foamie (Crazy Sukhoi 29 Depron) so I clearly can see rudder moving right ways...
