The world’s smallest drone – 2×2 cm and EHD engines

The “Ioncraft”

The “Ioncraft”, a mini-drone developed in California, weighs only 30 milligrams and measures just 2×2 cm. Unlike other mini-drones, it does not fly with the help of electric motors and rotors, but with the power of ions. Due to the built-in electrohydrodynamic engines, the “Ioncraft” accelerates by the collision of ions with neutral molecules, which are ionized and accelerated by the engines in an electric field. The world’s smallest drone can be controlled similarly to other quadrocopters, but the energy supply and data communication are not yet very mature.

EHD- Engine

The installed EHD engines are to be used in the future not only in drones but also in larger flying objects. They are highly important for research, as they can be used, for example, in space research, but also in agriculture, rescue operations and environmental research.

8 Steps to the FPV Pilot – The Book to Learn to Fly FPV Drones

Controlling an FPV drone is much more difficult than, for example, a DJI Phantom or DJI Mavic Pro. Finally, it is about racing equipment, which should move at the absolute limit. Information and strategies about the FPV fly and how to learn the fastest how to find a drone in the book “In 8 steps to the FPV pilot”. The book is a “how-to” for beginners and advanced.

How do I learn to fly a racecopter?

Practice by! (“No, really now?”). Is probably obvious. But what exactly you should practice, with which flight exercises you should start, you will find in the book. The “basic exercises” will help you even if you want to learn to control a camera drone safely. Later, the exercises and maneuvers that are only possible with an xxxxx ACRO-capable racing drone come later. To initiate the famous Split-S maneuver, for example, you have to turn the drone upside down – this is only possible with racers with modern FC’s. What comes after the head over-part you can read in the book.

Rotor Riot Ummagawd Acrobrat – the 3 “Freestlye frame on remix basis

Rotor Riot has released a new 3 “frame: the   Ummagawd Acrobrat . And the frame inspires!

Rotor Riot Ummagawd Acrobrat

Who is the “Umagawd Acrobrat” designer Tommy Tibajia?

Tommy Tibajia – better known by his pilot name Ummagawd (wonderful phonetic wordplay btw!) Is probably one of the most famous pilots on the FPV scene with Rotor Riot . Especially because he faces up to any challenge and if it is possible somehow masters (remember the Duga Dive ?).
Besides, he was always very tech-savvy and made some of the nicest build videos, flew in the DRL and starred in many Rotor Riot videos.

And lately? He has gone under the frame designers and brought to the market one of the most-discussed and most popular freestyle ramen in the remix.

Rotor Riot operates the 3 “hype with the Ummagawd Acrobrat

I myself am a big fan of the 3 “class: The HGLRC XJB-145 is currently my favorite racer and I think the 3 inch FPV quads are the most versatile quads. It is possible to bring them under the magical 250g but you can also strap on a GoPro session – besides they are usually very sturdy and not as loud as bigger ones and parts and lipo batteries are significantly cheaper than the big 5 inch FPV drones.

With the Ummagawd Acrobrat, Rotor Riot now serves this “up-and-coming” class and I’m really looking forward to seeing more movement.

3 “never looked so good

What is so special about the Ummagawd Acrobrat?

Unlike most of the frames on the market, Rotor Riot (or Tommy Tibajia) has given the Ummagawd Acrobat some special features that I like very well:

First, it is the reinforced frame – with its additional bracing on the front and rear, the Acrobrat should be particularly stable. And I think that you can see the frame too. Unfortunately, this is also due to a fairly high weight of 54g.

On the other hand, it is the long, flat construction adopted from the remix , in which the 20x20mm components are installed one behind the other and not stacked in a stack.
This ensures that the LiPo battery almost moves between the propellers and thus the mass is closer to the center , which provides better flight characteristics. Exactly this point I find really exciting and innovative.

Technical specifications

Diagonal: 163mm
Motor Position : True X
Motor Distance : 115mm

Should I buy the Ummagawd Acrobrat? Price in Germany

I like the Acrobrat sucker. So really good. And I’m thinking of building an FPV racing drone based on the frame.
If not the price. The Acrobrat costs until he is in Germany 60-70 euros, and that’s a pretty bang for a small 3 inch frame.
But I’m up for the build. What do you all mean? Should I get him?

TS100 Soldering Iron – The ultimate soldering iron for FPV (and at all!)

TS100 Soldering Iron – The ultimate soldering iron for FPV (and ever!)

The TS100 – the soldering iron for all cases

In the FPV scene, you can argue super: Everyone has their subjective views, why one propeller is better than the other … and the frame flies better than this. But the TS100 is different: Here, everyone seems united: the TS100 is the best FPV soldering iron! A consensus rarely experienced otherwise.

TS100 digital soldering iron

The advantages of the TS100

I’ll just do that in bullet points:

  • Set-up time
    The speed until the TS100 has reached its working temperature is simple  ?! I do not know anyone else who heats so fast. It’s always a blast to look at the small display and watch the numbers go by.
  • Portable
    TS100 is really tiny, light and has a huge advantage: it has a standard power connector, to which a with an adapter cable 4S or 6S batterycan be connected, so you can perform from the power grid and out in the field repairs and soldering work.
  • Weight and workmanship
    The TS 100 is hardly bigger and heavier than a pen. This, of course, makes him the ideal companion for the road. But still it is not a second-class device: The workmanship is impeccable and the soldering tips meet the highest demands.
  • Display and open firmware
    On the tiny but still very readable display, you get the temperature or the status (Standby, Hot …) displayed. Yes, the TS100 has a standby mode, because an acceleration sensor reveals the firmware whether the soldering iron is being used and turns it off when not in use in standby and later or drives him from the standby lightning fast again by simply put it in the Hand takes. That’s fascinating!
    The firmware is also Flashbar, there are already mods for the TS 100 and you can also program something yourself.

Various soldering tips for the TS100


All in all, the TS100 is simply an incredibly awesome product. I do not know anybody who was not fascinated after holding it in their hands and not one who did not have a big grin on their face after counting the 350 degrees in 15 seconds.

The disadvantages of the TS100

Yes, they are also available with this soldering iron. But it is already said: The disadvantages are negligible compared to the advantages:

  • Equipment

    • Power Supply
      There is no PSU included with the TS100. Therefore, when buying make sure that you also buy a power adapter.
    • Adapter cable
      The great strength of the piston is just that it can be operated on a Lipo battery. I would have been very happy to see an XT60 adapter in the pack. With the help of the XT60 cable, you can then solder independently of the socket.
    • Station
      The soldering iron has a thin Stifform and no feet to support, so a bracket is needed, so you do not touch if you want to put down the TS100.
  • Soldering tip remove only with Imbus
    Here one could again something points if the soldering tip would be changeable without tools. Because even in the beautiful black cardboard packaging you get the piston only if you remove the soldering tip with an Imbus. But that’s really whining at the highest level now.

My experiences with the TS100

I’m a big fan of the TS 100 Digital Programmable Soldering Iron. I have not touched anybody since I own this one.
In addition, I do not even use the power supply – because, with our power supply, the connection cable is quite heavy – with the XT60 adapter cable and a 4S battery leads the soldering iron not only easier – I am also location independent. So far, I’ve done all the work on my 3 “racer with the TS

And to be able to solder something in the field is simply awesome. It is seldom needed, but if: Then the TS100 is the one who makes the difference between “Goes nothing, has to go home” and a nice flying day!

FPV Freerider and FPV Freerider Recharged

FPV Freerider is a simulator for FPV quads . With this simulator you can practice flying very well with your spark on the computer without constantly crashing your drone. You can even use your own spark.

FPV Freerider is very simple and not necessarily the most realistic simulator in the field of aerospace physics – but it is not very demanding in terms of hardware (it even works on a mobile phone!) And unbeatably cheap ($ 5).

When successor  FPV Freerider Recharged was neatly turned on the graphics screw – but then also requires a correspondingly powerful system.

New Maps for FPV Freerider Recharged

Now a new map pack for freerider recharged has come out, and the maps look really nice. Also, the price for $ 3 is fine, even if I would have preferred the maps as a free update after I have already paid $ 22 (with donation) for FPV Freerider Recharged.

The Custom Level Pack includes:

– Big Hollow Bando
– Fifty-Fifty
– Treehouse
– 2018 MultiGP Regional Series Qualifier Track

MultiGP Universal Time Trial Tracks:
– UTT 1
– UTT 2 Tsunami
– UTT 3 Bessel Run
– UTT 4 High Voltage
– UTT 5 Nautilus
– UTT 6 Fury

If you already own FPV Freerider Recharged then you should get the pack in any case, whoever does not have FPV Freerider Recharged can get it for only $ 10 .

Alternatives to free-riders

Freeriders / Freeriders Recharged are two extremely popular FPV simulators. But they are by far not the only ones. Interested people should also take a look at this:

Freerider vs. Liftoff vs. Velocidrone Vs. Rotor rush


Unfortunately, Liftoff is only included on the Steam platform , but probably the “cutest” product on the FPV simulator market. In addition to good flight physics, there is a heterogeneous selection of maps and various modes, including a freestyle mode in which your FPV freestyle moves are scored points. Liftoff is my most used simulator at the moment.


The Velocidrone , created in collaboration with TBS, is described by many pilots as the simulator with the most realistic flight behavior.

Rotor rush

Especially racers swear by Rotor Rush . Unfortunately, Rotor Rush is really designed for FPV racing and not as flexible as the requirements of freestyle pilots.

(KingKong resp.) LDARC Tiny 7X – Monster fun in the Tiny Whoop class

KingKong Tiny X7

(KingKong respectively) LDARC Tiny 7X – Monster fun in the Tiny Whoop class

KingKong is now called LDARC – LDARC Tiny 7X

The company KingKong was renamed to LDARC (I assume for trademark reasons). When the shop was called KingKong, they had two great successes with the small quads in the “Tiny Whoop” size: the KingKong Tiny 6 and the KingKong Tiny 7.

In addition, KingKong has now under the name LDARC not only 2, but 3 successors brought: LDARC Tiny 6X, LDARC Tiny 7X and who would have guessed: LDARC Tiny 8X!

KingKong Tiny 6 Micro FPV Drone TinyWhoop Drone
KingKong Tiny 6 – The old model of success

What is “Tiny Whoop”?

The LDARC Tiny 8X is no longer a “Tiny Whoop”, but it is almost too big for that. The term Tiny Whoop was coined by the company However, the term Tiny Whoop of the FPV scene is now abused for all mini-drones with 1 “propellers that you can fly FPV. The Tiny series is a copy of the TinyWhoops.

LDARC Tiny 7X – More Power => More Fun

I let out a Tiny 7X. The LDARC Tiny 7X is slightly larger than the Tiny 6 or Tiny 6X and has bigger engines, a bigger battery, and more power!
But it is still a little whoop with prop-guards, so you can easily fly inside and bump into things or people, crash, etc … that puts away the little easy.

But the special thing about it: unlike the KingKong Tiny 6X, the Tiny 7X simply has more mass, which is why it simply pushes away the very small branches that cause a 6X to crash on flights outside, for example. Here is a video of the first flight, due to lack of skill you can maybe see what I mean?

The part just makes a hell of a lot of fun, especially because you can quickly take it into the cigarette break and make a small round.

I bought with the RTF ( Ready To Fly ) package ( BG , Amz , GB ), which contains everything so that you can fly: The quad, a battery, charger, battery level indicator, a really nice suitcase, and a small spark,

KingKong LDARC Tiny 7X RTF Kit Mini Drone Drone Remote Spark
LDARC Tiny 7X RTF Kit with remote control

This can be started directly, but what you should consider or should have is, of course, a FPV goggles .

The special in the RTF kit: the remote control

What is so special about the kit: It is probably the LDARC X8 RC radio remote control, this is equipped with a CC2500 transmitter, which also dominates Frsky !

This could, as they are not particularly cool, but just so useful, my “travel spark”. It should be noted, however, that you have to flash the FrSky protocol on it and if you do that, you need to replace the receiver on the Tiny X if you want to continue flying this way.


FPV AIO Cams – All-In-One Cameras for FPV Drones (and Spies)

FPV AIO Cams – all-in-one cameras for FPV drones (and spies)

What is an FPV, AIO Cam?

An FPV AIO Cam is a small component that combines a camera, a video transmitter (VTx) and an antenna. This component only needs a power source and you can already receive the signal with FPV goggles .

Such a tiny camera can then be glued to all sorts of things and see the world from their perspective. If you can now control the whole thing (like race models or threats) you have a real “first-person perspective” experience.

Eachine E010 with AIO Cam

How do I connect an FPV AIO Cam to a drone?

It is enough to connect the cam sufficiently safe with the drone. “Sure enough” means here: It should not be able to slip or change its angle. Sometimes it is sufficient to attach the cam with a rubber band, sometimes help mounts specifically for the cam were built. The AIO cams are quite light, usually between 2 and 6 grams.

Where does the Cam get electricity from?

It is also not necessary to somehow connect an FPV AIO Cam to the drone. You can equip the camera with its own power supply, eg an S1 Lipo battery . That’s what we did with our DJI Mavic Air FPV .

But if you want to upgrade a tiny drone like the Eachine E010 to such an “all-in-one” camera as a real FPV drone, you need to tap the drone power supply, because the drone will not have enough power for another battery.

Solder AIO Cam to power supply

Probably the best-known AIO system is the Eachine TX03 ( Banggood)


Eachine TX03 AIO FPV Cam Camera

The next generation: FPV AIO with DVR

A very exciting development: There are now FPV AIO Cams with integrated HD video recorder (DVR – Digital Video Recorder). Then you put a small MicroSD in the AIO Cam and can take the picture with much better quality than it receives on the glasses.

Eachine DVR03

For big threats, you usually use either a GoPro Session,   Foxeer Box or a RunCam Split   (for the latter, the same lens/camera is used for both FPV feed and HD recording => ladder than with extra). Camera).

Foxeer box
Foxeer box

Now it’s also available in AIO format, and the  Eachine DVR03  weighs just under 7 grams. This makes it almost possible to build the whole thing on a Tiny-Whoop and record the flight adventure in a beer garden, kitchen, and office in HD quality! ?

Eachine DVR03 AIO FPV cam

Unfortunately, the output of the FPV feed suffers somewhat from the recording. If the DVR is activated, you will not have as many FPS (frames per second) as normal.

And yet I’ll get the thing well – I have the guts to record a flight with a mini-drone in something better quality!

DJI Mavic Air FPV

DJI Mavic Air FPV

We have made our newly arrived DJI Mavic Air FPV suitable

The Mavic Air is probably the hottest camera drone currently, but we are actually not DJI aviators but FPV Racer pilots. And what do you want as an FPV pilot? Exactly: The thing from the first-person perspective fly, but do not stop ‘staring at the phone’.

So we built a DJI Mavic Air FPV. ?

DJI Mavic Air FPV FPVRacingDrone
DJI Mavic Air FPV

Can you fly the Mavic Air FPV?

Joah, you can go. But it takes a lot of getting used to. With the goggles you have a wide-angle image for FPV, which does not necessarily match the flight characteristics of the DJI. But you can definitely steer well from the first person perspective and above all have no time delays as on the phone. So with a bit of practice, that should allow you to fly a bit of proximity with the Mavic AIR.

What we used to build the DJI Mavic Air FPV

Felix has just designed a 3D part, which keeps the AIO FPV Cam. Originally, it had side panels when we got it from the 3D printer, but unfortunately, they did not quite fit under the propellers. So sawed off and done quite provisionally with tape to the Mavic. Because that was surprisingly good, but just with the back of the tape n 1S battery on it and our “Jenny Air FPV” was ready =)

The fastest drone in the world (267 km/h) – Quadmovr Movr5r2 F80


Quadmovr (yes, it is written in this way and not Quadmover) from Germany is probably the best-known LOS pilot in the racing drones area. One of my favorite videos comes from him (especially because of the sound), you’ll find it on the homepage. His current Movr series arguably the fastest drone in the world, as he is also one of the busiest designers, pushing his builds to the limit.

Speed Freak

Lately, he’s been focusing on one thing: Speed!
With his Movr frames, he sets one record after another. To measure, he uses a telemetry unit mounted on the race quad which sends the data to his Taranis remote.

Quadmovr FrSky Taranis X9D Radio Spark FPV Racing Drone Drone FPVRacingDrone World Record World record Speed ​​Fastest drone in the world
267 km / h !!

The fastest drone in the world

In the Miniquad area, it should thus hold the world record in terms of speed (as of March 2018): The Movr5r2 f80 flies an incredible 267 km / h with a 6S battery (which is 166 Mp / h in retard units).

Here is his record flight:

UPDATE: The DRL R3 Racers has even come to 288.6 km/h (179.3 Mp/h) with an outlandish 10S Lipo 80A ESC equipment. Wow. But Quadmovr still holds the 6S record.
