Since I got too much free time I decided to build my self little ground station with diversity. I found interesting blog here on RCGroups, where member used simple HK video switch and arduino board. http://www.rcgroups.com/forums/showthread.php?t=1955631

For housing I used external disk drive unit that died few years ago and modify it. For voltage monitor I used simple LED display with integrated PCB that I found on ebay for 2-3$. Most of other parts were laying around at home (arduino, resistors, cables, connectors and 3 RC305 receivers)....Continue Reading

Since no sound about motor and Naze 32 controller, I decided to do some work on electronics. All FPV gear is soldered together, also added home made LC filter and finished all connections. At the moment model weights 321g with 3S 1000mAh 35C lipo.

Since my old radio Multiplex EVO 12 just died few days ago, I`m thinking of buying new one...
Now here is big question what to buy? Since I was comfortable with 12 channel radio I do not want to go on less than that. So I`m thinking to buy new radio from Multiplex, that come out not long ago. I use Multiplex radios since 1999, so I will stay on them.

At the moment my eyes are on Multipelx Royal SX 16, but big issue for me is to decide what color should be, so I need help.

Action comes in yellow color. It looks different than most of transmitters on market.
Elegance comes in black color (more dark gray). It looks elegant, but boring and not so recognizable as old Royal EVO or PRO were in silver color.

Guys, what do you think?

Someone asked me how I manage to do such nice holes in the ribs. The trick is very simple, of course, with the right tools.

Tool I used is a piece of plywood or other material appropriate thickness. I made ​​several of these devices in various thickness plates.

You need sandpaper between 100 and 150 grid. Best is the one with fabric on back side. You also need some double-sided tape.

Make sure that sandpaper is few mm wider than the length of the three sides viewed from the top of the tool. (see picture)

First glue sandpaper to one side and gently bend and then set it to the other side and push it all to clog together nicely.


Tool is useful for grinding round holes, transitions between straight and curved lines openings ... Depending on the pressure which we perform to the piece, changes a profile of the grinding tip of tool. At the beginning perhaps not so much because the sandpaper is more stiff, but once everything gets soft, it works much better.

I will show you how to transfer pieces from plans to material. It is used for all kind of woods and ply woods.

It is very simple, all you need are pieces of paper printed on a laser printer , some cotton wool and acetone.

The best is to arrange parts to maximize material and that all the pieces are made of the same material are grouped together, so that accidentally you don’t cut the ribs from plywood that should be made of balsa wood.

Printed side of the paper you have to turn to the material and place it. Secure paper with a tape, that later will not move. Then take a cotton ball, and impregnate it with acetone, and soak it. Rub over the paper only to wet paper and paint. If the paper is too soaked, the lines will be blurred, but if too little, you will see bad impression on the material.

If everything is nicely done, on the material will remain a beautiful mirrored footprint.

Hello all!
This is my first blog entry. At first let me tell you few things about me. My name is Kristjan and I come from small town Šentjernej in Slovenia. I`m 34 years old and have been creating models since I was 9 years old. At age 16 I got my first RC set and since then I flew rc gliders and electric planes. Last four years I was more in to multicopters, but my passion for planes never died.

Now let`s color nylon parts.
Process is very simple, all you need is:

Fabric Dye color (any color )
White Vinegar
A Small pot
A small strainer (optional but highly recommended, or it will take you some time to take them out from pot)

Toss your vinegar and fabric dye color in the pot, heat it to a low boil and mix it time to time, so you get mixture without soil on bottom. Then drop your nylon parts in the strainer and dye them till they're not desired color.

If you pull them out too early, they will turn out very pale. Heavier and thicker nylon requires more time.

After 5-10 minutes or so, parts are ready to take out and washed under water till you get clean uncolored water. Then just dry parts using paper towel or hair dryer.

Best way is to do this somewhere outside, since boiling vinegar creates nasty smell and it my bother your girlfriend or wife....
