More Turnigy 9x ideas

I am currently going thru all options for ArduPlane that I intend to use in my Skywalker.

I want to keep my current setup on the Skywalker – a 4 servo wing requiring 4 channels. This way I do not have to reverse any servo internally or change setup if I want to go back to the Spektrum radio again(failsafe)
Arduplane can fly on its own(UAV) and I didn’t know that flaps could be used in the software but I was not going to add this anyway. I do not intend to use any camera stabilization either (also optional).

What I do want is to have more options available from Arduplane – there are several modes:

APM Mode GCS Display
Manual "Manual"
Stabilize "Stabilize"
RTL "RTL"
Auto "Loiter"
Loiter "Loiter"
FBW-A "FBW-A"
FBW-B "FBW-B"
Circle (retains previous mode display
Takeoff (retains previous mode display
Land (retains previous mode display

I want to use some of them on a single stick – so the option is to use a knob.
Here the problem can be seen – the knobs on the TGY 9X has no index and it is very difficult telling how far you turned the knob without looking at it or the display.

I want to add indexing. I have to think about this to see what I can come up with. Possible a small spring that feel small grooves(holes) in the knob itself (or replace the knob with something indexed)

GPS

Today I got a parcel from DiyDrones. I ordered a GPS for the ArduPilotMega and Oilpan shiled I have. The GPS makes it possible to use more features of the board including adding waypoints(UAW) and return to home if signal is lost.

It will be incorporated into the Skywalker as soon as I get time to tinker with it.
A few options will be controlled by a switch on my TGY 9X radio.

The software will be ArduPlane

Here you can enjoy the GPS

Swift II LED pictures

I was asked to explain how I did the LED modifications. Here are more images to show how the LED-strips are inserted into the foam.

The winglet LED’s (red and green) are mounted with the supplied sticky-tape this way the red and green does not make the foam glow but they are more directional. This improves visibility in air as it clearly tells me where I’m going. The white LED’s are there to make the whole wing glow.

Swift II night

I took the Swift II for a short flight to demonstrate how effective the LED’s are in air.

Swift II LED

I mounted a LED strip to my Swift II. This will make it possible to fly in total darkness.
2 40cm long cuts where I inserted the LED-strips standing in the foam. The cuts are about 15mm deep so I can squeeze in the 10mm wide strip and glue the foam together again.

Here is an image, this is the Swift II lying on my tiled floor, belly-side up towards camera, It is even brighter from the other side.

Forum update

WordPress released a new version so I downloaded the new version. It seems OK. I will have to update the Lightview script manually as this usually does not work. There is a backup function that I used once but tend to always forget…anyway now it is done. I want to thank Nick Stakenburg for LightView

Turnigy 9X more mods

Did you think I was finished? There is a problem with the antenna connector. It fits the supplied FRSKY DIY antenna inside the original hole but the FRSKY patch antenna is bigger in diameter where you grip it to thread it onto the connector. The bigger diameter prevents it from slipping into the stock hole. I simply used a small saw to cut off the plastic tubing and flanges and I will use a fine file to make it flush with the rest of the transmitter. A piece of 3mm plexiglass was drilled and shaped to fit on the inside. This allows the FRSKY DIY antenna connector to be fastened in a secure way and it allows me to change antenna whenever I need to. Long range patch antenna for FPV and short range (stock FRSKY) for closer proximity flying.

I also changed a bit in the programming to suit my needs as the settings was donated. The whole radio system, the new receiver and the PPM features got my brain ticking…I think I will sell my Spektrum DX7 and all my receivers(AR700+satellite and a few AR6100′s and a AR6100E)

This will force me to rebuild the Skywalker and I already have plans for that anyway…adding the FRSKY D8R-II to the setup instead of the AR7000.

Severe lumbago

I think I got Severe Lumbago again. Massive pain in my lower back…I dislocated a disc a little. I cannot work at the moment and almost all work at home halted as well. If I’m lucky I can do some soldering at least but I have no no strength for the workshop.

Turnigy 9X/frsky PPM

I have been working to get the PPM signal working on my Turnigy 9X with FRSKY diy module. I found out that the receiver (D8R-II) needs to be flashed/reprogrammed to enable PPM out. I purchased a FRSKY UPGRADE LITE and a D4FR receiver from GiantCod in UK.Fast chipping, great service and in stock!

Great – now I have a Upgrade Lite so I can reflash the DIY module and my D8R-II but the best part is that D4FR has PPM out by default. I only bridge ch3 & 4 with supplied jumper and hey presto!

I initially purchased this little 4ch RX to be used indoors on my foamie – but in PPM it has 8 channels so I can use this on my MultiWii Quadcopter.

A while ago I contacted a Swedish forum member discussing the Turingy 9X and he was kind enough to send me his ER9X file – the programming in the radio. I simply binded the 4ch RX with the radio and connected it to a Paris board with a single servo wire – way cool – all channels work and I have even more options now than with my Spektrum DX7 and AR6100′s I used earlier.

Now I can control AUX1 and AUX2 and I can control angles of camera gimbal If needed.

Super cool – now I have to reflash my Paris-board on my Quad.

Thank you Fredric for the ER9X config

Quadcopter rebuild

After the crash I stripped the Quadcopter down for maintenance. I have made a few improvements and re-soldering of wires. Removed the Remote switch and added AUX2 to MultiWii instead. This disables the option for a buzzer but as I have an external LIPO alarm I do not need the buzzer connected to MultiWii.
Now I can control acro/stable mode on 1 switch and Barometer on 1 switch. So I will start testing with the BMP085 connected and so far it seems OK.

When the remote switch is gone I route the LED’s to Paris LED solder instead. this lets MultiWii control LED’s so when motors are active the LED’s lit up full strength (they are dim when motors are off)
The LED’s now flash when configuring MultiWii – I also connected the status LED that flashes in the same patterns.

All my boards are equipped with the latest offering of MultiWii 1.9 as there were a few glitches in early release (might have caused my crash) Another great tool is the Serial LCD – use it for configurations or controlling i2C error status or what you need to monitor.
