I received a private message today I'd like to share here and answer publically so the answer may benefit all.

Hi, I have just received my Taranis in the post! And I was looking at adding my own model images, however when I plug it in window vista installs the drivers for a game controller and now I cannot load up my own and your model images? Any help would be appreciated. Thanks
name redacted

There are a few requirements for model icons and also a few for splash screens.

Model icons must be
  • exactly 64 px wide and 32 px tall
  • saved as .bmp files with 4 bit
  • placed in the SDcard/BMP folder
  • have 10 characters or less with no spaces and a .bmp suffix (Note: sounds must be 8 characters or less with no spaces and a .wav suffix)

The problem most people have is getting them saved as 4 bit images. 4 bits gives you 16 shades of gray - theoretically. The quality of the Taranis shades 12-16 are basically transparent. shates 1-4 are basically saturated - leaving realistically 9 different shades.
To edit icons, I work with them in their native resolution and start by converting the image to grey scale to purge any colors. Programs such as Photoshop allow you do use commands such as "Black & White" rather than doing a direct desaturation so you can darken or lighten certain hues so they stand out from one another.
I don't want a grey rectangle background; that looks cheesy - so the first thing I do is to remove all of the background of the icon....Continue Reading

Simple question:
Does the play button work for you in CompanionTX using Windows?

Our Third Annual Wings for Wishes is in the books. It's gratifying to see so many people pitch in in so many ways to help us help Make-A-Wish Foundation make wishes come true for children with life threatening conditions. Rather than name names and miss somebody important, I'll just take my hat off to the man that has brought this together the past three years - Clark Hymas.

This photo is of Clark Presenting Leslie Woodfill (Regional Co-Director at Make-A-Wish Alaska and Washington) with a check for $7170.


I want to shout out to the vendors I worked with to help support this event :

This is my understanding of the "buddy box" functions of the Taranis. There are enough different parameters to play with that I'm not sure of all the possibilities, so I'll explain what works for me, and then in the future add more information as it's learned and tested.

I find the term "Buddy Box" somewhat misleading. In truth what we're doing is establishing connection for a CoPilot connection.


DEFAULT TRAINER SCREEN.
To access the default trainer screen give a long press to the MENU button and then press PAGE twice.

The CoPilot connection can be established with many different parameters, and different transmitters. If a transmitter can output PPM signal it can be used for a CoPilot connection.

In the best possible scenario both transmitters will be Taranis, but that's not necessarily going to be the case. Fortunately the Taranis can be either the primary or secondary transmitter. The primary transmitter is also referred to as the "master" or the "instructor" transmitter. The secondary transmitter is also referred to as the "slave" or the "student" transmitter.
There are three different primary-secondary possibilities.
With the Taranis
  • as the primary transmitter,
  • as the secondary transmitter,
  • both the primary or secondary transmitter.

As an additional parameter, the connection can be either wired or wireless.

Regardless of whether the connection is wired or wireless, the transmitter that...Continue Reading

EDIT: This is the basic sequence you'll do
  • modify S.port cable as per instructions and connect S.port cable to FRUSB cable
  • open Device manager so I can see what port is added when I plug in the FRUSB cable
  • Plug in FRUSB cable to TX and USB as per instructions.
  • Set to port that comes up with USB to UART (FRUSB) (Port 3 in this case)
  • Run frsky_update_Sport.exe as admininstrator
  • Click File - load XJT_131105.frk
  • Turn on Transmitter
  • Press download
  • Wait until finished
  • Press End



Unzip the attachment.
Obtain the cables FRUSB-3 UPGRADED CABLE and FRSKY SMART PORT CONVERTER CABLE.

[I actually bought two of the smartport converter cable, one for the XJT and one for the other smartport devices]

Modify the smartport cable by removing the red wire and moving the black(or brown) wire to the center spot in the plug as shown in illustration. And follow instructions for connecting cable to TX inside the module bay.

You'll run frsky_update_Sport.ext from the zip file and chooose the XJT.frk file to upload to the transmitter.

I'm somewhat intrigued with the age of those who are purchasing the Taranis. A couple people have told me that their age was a factor in choosing whether or not to purchase the radio. I've also been told that RCG is only used by younger modelers - and while that may be somewhat true, I'm not sure if I believe that either. So... I thought I'd conduct a poll.

Not sure how much information I'll be posting here about the Taranis - but I'll start with a graphic that was requested.

I've seen lots of trays. Over the past few years I've taken pictures of every tray I saw and compiled a collection of what I likes, and didn't like so much. My wife bought me a wonderful tray that requires a harness to wear properly. It was expensive and effective, but the harness left alot to be desired and the tray had some features that bothered me a bit. One thing is I want my hands to rest in one place so that they are anchored to datum (as in surveying). Secondly I wanted to be able to reach all of the switches easily. I wanted the transmitter to hang level from the strap - and I wanted a strap - not a harness. It needed to be somewhat compact but also protect the transmitter. I don't know if I succeeded at making the perfect (for me) tray or not yet, but for now it seems to be working pretty good.
Its laser cut from OPTIX 18" z 24" .220 in. Acrylic Sheet. The spring on the bottom was made from LEXAN Polycarbonate Sheet that is .093 inches thick. Plastic materials were purchased from Home Depot. The T-nuts and hex cap screws are 3mm. Lexan bends very easily when heated with a heat gun - but easy not to get it too hot too fast or it will bubble and ruin your surface. Acrylic is even easier to bend because it is not so likely to bubble, but will if heated too fast.

I've included several photos of the final product and an zip file with two illustrator files for cutting.

Lightening holes in foam is nothing new. The problem is that rigidity and construction integrity is compromised in the process. My goal is to try to eliminate much of the foam in the wings of a "flying W" without sacrificing strength or rigidity.

The Flying W is basically a design similitude of the Robbe Gemini - which was reverse engineered and plans posted on Watt flyer and RCG about 2007 or 2008 as the "Capricorn". The plane is actually an amazing plane and an absolute hoot to fly. The lower the wing loading the better they fly.

So as I'm learning to use a laser cutter I needed a more challenging project and so the Swiss W was born. In addition to the honeycomb pattern cut into the depron, used a 12mm CF tube back bone which extends from the motor mount to the root of the stab. This back bone will be the hard anchor point for the battery and ESC. The firewall is constructed from poly-carbonate that has been heat shaped so it has a 4 degree up thrust. I predict that as the thrust increases, the firewall will flex forward to reduce the amount of up thrust -- possibly helping to remedy one common problem with the W/Capricorn/Gemini -- and that is altitude gain on high throttle. Yes, you can mix in elevator -- but that increases parasitic drag -- a changing thrustline could be more efficient.
Below are the building photos so far.

I used Ultrakote, MonoKote, and New Stuff for different areas covering. New Stuff is much lighter -- shrinks less so is less of a problem deforming the panels. Next preference was ultrakote. MonoKote was really heavy, needed much more heat to start with, leaving less of a range for adjustment of warps and such.

To do it again I'd just use 100% new stuff from alofthobbies.com

In the upper left corner of the RCG menu there is a link to "My RCGroups".
See the attached image for the link below that which will cure chronic pains in the butt.

I'm going to use this blog to keep track of mixes used for the 9x radio.

This first post is a simply gyro setup. A curve is established so the pot that controls gain can use the full range of motion to yield numbers from 0 to 100 -- thus all numbers are positive numbers. Normally the pot range runs from -100 to 100.

I have two gyro gain channels -- channel 5 and channel 6. The gain for each is controlled by the corresponding pot. This allows for adjustable gain. If I want a specific value for gain with no adjustment -- or modify a curve to establish a narrow band of adjustment.

I fell into love with the Flysky 9x transmitter quite by accident. I was a loyal Futaba jihadist but purchased two Turnigy 9x radios for the ridiculous price of about $50 each. I thought that IF they even worked perhaps our club would like to purchase them for use with the club trainer as a buddy box system.
Unfortunately, when they arrived the buddy box connection would not work. I went to RCG for help and leaned I needed to remove the TX module from the student Tx for the connection to be functional. This worked, but the trainer switch was impossible to use because the instructor had to hold the trainer switch while being in control -- stupid setup anyway. I went to RCG for help again and learned about the greatest thing since .. well.. since the Wright Brothers. er9x firmware. I replaced the stock firmware with er9x (grossly oversimplified) and within weeks the 9x radio was well on it's way to replacing my love for my Futaba 7c (which is now for sale).

The next 6 months I learned quite a bit about programming with the 9x, the hardware, and making simple mods that improved functionality but also -- appearance. Cause... ya gotta have the best looking TX at the field...right?

So my project is to remake a Flysky 9x radio -- add a programming board, bright colored LED backlight, large colored ends for the gimbals, and a case colored like none other. Probably also a stand, and who knows what else before I'm done.

Well, here is step #1 -- the case. I sprayed the case with Ace Appliance epoxy spray paint. I'm not sure if the rattle can is really epoxy -- but that's what the label says.

I started by removing all of the electronics, switches, gimbals, labels, etc and then cleaning the case with denatured alcohol and finally spraying the case with the rattle can. Below is the result of step 1.
