Shinto Servotray for MKS 6100 (Glider by Vladimir’s Model)

This servo tray is for MKS 6100 servos and particularly designed for an electric version of Vladimir’s Model Shinto F3F/B/T/J glider. It could likely be used for other F3x gliders as well.

This mount enables to easily and securely fit and fix both V-tail servos, one behind the other, deep into the fuselage to keep the front space available for motor, controller and the battery (3S in my case). The location of both servos is behind the wing servo cable entry point into the fuselage to prevent the moving servo arms to accidentally damage the cables.

The tray is fixed with two 8mm M3 screws. One using the existing cut-out for the F3B launch hook and an additional one approximately 14cm further behind where an additional hole needs to be drilled into the fuselage. It hurts, but it helps. The counterpart is a 6mm M5 grub screw with a M3 inner thread.

I recommend using Loctite (or similar) to secure the screws.

What you’ll need:
1x printed servo tray
2x 8mm M3 screws
2x 6mm M5 grub screw with an M3 inner thread

If you would like to make modifications starting with this design, just send me a message. I am happy to share the original Fusion 360 file. To download the STL file and for infos regarding the printing, please visit Thingiverse.

DIY FrSky Horus X10(s) Car Charger

For those familiar with electronics, this is the short version: Connect a 12V cigarette lighter adapter to one and a barrel plug to the other side of a step-up converter and your car charger is done. For more details, read on…

The X10(s) comes with a wall charger and a 2S 7.2V 2600mAh Li-ion Battery. If the battery is not fully charged, and sometimes even if it is, the transmitter (TX) might not get through an entire day of slope flying. So here is a way to charge it through a 12V cigarette lighter adapter or your 12V DC power supply unit.

This solution does not call for any “invasive” mods like soldering inside the TX, drilling the TX housing, changing battery chemistry and so on.

Side note: The standard FrSky “Wall Charger” coming with your radio is not a charger with all the charging intelligence and algorithms inside it but only an AC-DC converter providing a constant 15V 1A output. The charging intelligence is on a printed circuit board (PCB) attached to the Li-ion battery inside the radio and it decides how much charging power is coming through and when to stop. In other words, all we need to is to put together a device which provides constant 1A at 15V.

The main component is a so-called step-up volt converter which is sold on eBay for little money. There are many models, some with a LED volt display. The one I bought is simple, cheap and small:

The step-up converter I chose increases voltage from 3-24V input to 5-28V output and can provide up to 2A. It is important to note, that it can only increase the voltage and not reduce it. So if we need a 15V output to charge the X10(s), this specific converter needs an input between 3V and 15V. In my case, I will use the car battery as a power supply.

Components used:

  • 1 Step up volt converter
  • 1 Car lighter adapter for banana plugs
  • 1 Set of banana plugs
  • 1 Barrel plug: 1.7mm inside, 4mm outside, plugs into the X10(s)
  • Cable, shrink tubing and a couple of plugs

Optional: Instead of using a new barrel plug, you can cut off the one at the standard wall charger and connect it back using a plug (e.g. XT30, but almost anything will do). That plug would then also be used to connect the step up volt converter.

Edelweissweg & Wisshornweg (Trift)

Zermatt (1620m) – Alterhaupt Edelweiss (1961m) –  Trift (2337m) – Schweifinen (2503m) – Zermatt
900m ascent / 900m descent
13 km / 6 hrs

After going through beautiful houses with balcony full of cheerful flowers in the east side of Zermatt, we found a path, leading steep uphill to the restaurant Alterhaupt Edelweiss. It perches on the rock above Zermatt, its white building visible from anywhere.

After a refreshing home-made ice tea, the path follows the narrow gorge and its serene stream. Here, there is no gondola nor mountain trains, nothing but quiet nature. That is not so easy to find in an area as developed as Zermatt.

The higher we go, the valley opens up and we see several impressive peaks and glaciers.

After some serious uphill, we arrived at the pink Trift Mountain Hut. I realised that I had been here more than 10 years ago.

We hang out in the wide basin near the hut for a long time, basking ourselves in the warm sun, having our delicious self-made sandwiches (away from the crowded mountain hut restaurant), taking many photos, listening to the hut owner playing the alphorn.

We changed our original plan which was to head back down the same way we came up and continued up a bit to walk a loop.

Above at Schweifinen (2503m), we have a phenomenal view of the entire east valley: Matterhorn, Klein Matterhorn, Riffelberg, all the way down to Winkelmatten where we stay. I was very happy that Philippe suggested this little scenic detour.

From there the path was steeeep downhill!  With Zermatt visible 900m below, we started that long zig-zagging down the mountain. While descending the narrow path I slipped on a tree root and got a mountain gift in form of a blue ankle for weeks…

We were relieved to be back in town to put our feet up…

Hörnlihütte (3260m)

Convinced that Matterhorn is the most beautiful mountain in the world, Yasuko’s birthday wish was to spend a few days in Zermatt. Our friend Patrick was so kind to let us stay at his studio with a fantastic view of that magnificent mountain. We could have sat in the studio just watching that magnificent mountain from the window, but not with Yasuko, of course.

For non-climbers, the closest you can get to the Matterhorn, is the Hörnlihütte, the base camp for the Matterhorn peak ascent. That’s not something one needs to tell my darling twice. So the  birthday wish became a hike, as the weather forecast promised a sunny day. We packed the sandwiches and off we went…

The Hörnlihütte has been renovated a few years ago, is very modern and serves nice and simple Swiss food (Rösti and similar stuff, that is). Every hiker takes that same picture on the terrace with the Matterhorn in the background. Except us, we took many 😁.

We were a bit worried about the descent, as there are some really steep and scary parts, with a ladder, ropes and almost vertical drops of a few hundred meters right next to the secured path. But it all turned out to be quite manageable. We just avoided looking down for too long.

On the way down, Yasuko expressed a wish for her next birthday. The guess is yours…

Findeln Glacier hike & Chez Vrony

Blauherd – Stellisee – Fluhalp – Findeln – Winkelmatt

It started in the complete fog, when we got out of the gondola at Blauherd this morning….

but soon it cleared out and picturesque lake Stellisee reflected the Matterhorn in its water!

Our plan was to do the 5-lake hike but we saw the tempting glacier beyond the lake so we walked up to the moraine which is simply…

… spectacular. Rocks, stones, gravel and sand pushed by icy snow creates moraines of massive dimensions. Nature at work.

A nice stop at the beautiful and well-known restaurant Chez Vrony.

Eataly 🇮🇹

This trip unexpectedly turned into a fantastic food adventure. The best I can remember (outside Japan, that is). Ohhh… these black smoked gnocchi with truffel and asparagus were to die for and the gnocco fritto a surprising start into a  great meal.
