Walkera Goggle 4

Walkera Goggle 4 in-depth review with pros and cons

walkera

 

Welcome the Walkera Goggle 4 this is my first FPV goggles review. On the primary impression, this Walkera Goggle 4 appearance far better so I’m hoping that should perform also far better, especially which isn't the least expensive FPV goggles that you can buy.

Walkera announced their FPV Goggle 4 series in two models, an ultimate one and also a basic one. I believe the most important features of the Walkera Goggle 4 Premium on the Basic model include the HDMI input along with the DVR function. HDMI connection is a must have if you wish to fly via FPV goggles consumer quadcopters such as the DJI Phantom 3 and 4. Regrettably, the standard version is the one I received for review.

Over the time, Walkera shifted from aerial quadcopters to racing quadcopters. They launch new racer models almost every 6 months, from small ones just like the Rodeo 150 to big ones just like the Furious 320. Lately, to be able to offer complete FPV bundles, they started the production of FPV goggles.

As many times Talked about FPV glasses are made to provide the ultimate FPV experience, in my view, they're suitable just for experienced pilots. Honestly, it truly is more difficult to control the quad through FPV goggles compared to the conventional way (at least in my experience).

Walkera Goggle 4 FPV goggles review

walkeraI purchased the walkera goggles 4 from Banggood and the package was sent out quickly and delivered in 14 days. This is the first time that I have no complaints regarding DHL’s shipping services.

The FPV glasses comes in an elegant cardboard box which induces the feeling that we are dealing with a quality product. Inside the box, I found beside the Walkera Goggles 4 and its battery: AC/DC adapter, micro USB cable, two 5.8G antennas and user manual.

In order to disperse the weight, the battery pack is located on the head strap in the neck area instead of being integrated into the goggles. The connection between the headplay and the power source is realised by a short USB cable.

Both design and build quality are excellent. Good work Walkera! The straps are adjustable so it’s easily adapted for any head size. In order to allow good heat dissipation, on both sides, there are vent holes. Anyway, in my opinion, they should add also fan cooling to prevent fogging.

In the front part, there is a black spot that firstly I thought to be a camera. Unfortunately, it’s only part of the design without any real function.

On the top part of the goggles are located two SMA connectors. The centre one is dedicated to the LHCP antenna and the left one for the rubber ducky antenna.

An AV Input RCA plug is provided on the bottom of the FPV goggles to allow you to connect another video source (like camera, TV or media player). Switching between external video and internal 5.8G receiver can be done using the big black button located on the top of the goggles. I’m planning to use this feature by attaching a small camera (like the RunCam OWL Plus) to the Walkera Goggle 4 in order to have a dual point of view (drone and pilot).walkera

In order to allow easy and convenient settings, instead of tonnes of buttons, the goggles feature a stylish joystick. By pulling the little stick backwards can be activated the configuration menu. By pressing the stick as a button can be changed the current reception band (A, B, E, Race and IRC/FS). Toggle between the channels can be done using the CH-Up and CH-Down buttons.

Although the Walkera Goggle 4 basic doesn’t have a built-in DVR, you can add an external one through the AV Output. You can find the plug located near micro USB power socket (right side behind a flap).
Walkera Goggle 4 highlights

Walkera Goggle 4 review – Usage

While these FPV goggles were designed to work alongside Walkera racing quadcopters I think they are compatible with mainly almost every other 5.8G systems. I tested it with my TBS Discovery and it worked flawlessly even withwalkera my custom racer. Wearing this Walkera Goggles 4 is comfier than the other FPV glasses which I own. Really the only problematic spot is around the nose where the frame is a bit obscure.Walkera Although I just read on another review made by a fellow that there is enough room to use it with prescription glasses I haven’t managed to do so. In my opinion, it is very hard to design an FPV goggles that fit in eye glasses.In the introduction of my review, I said that the control stick is a great idea. After few usage, I changed my personal opinion and I would prefer a multi-button solution.Thanks to the dual-antenna design the playback quality signal were very stable. I managed to fly about 300 meters far for me till the video signal started to be jerky (using 600 mW TX). Although the LCD screen is not HD, the image quality is more than acceptable.The advertised operation time offered by the 7.4v 2000mAh is about 2 hours which in my opinion it is enough for FPV flights but in case you want, even more, you can attach any external USB power bank

What Is Drone Racing And Where To Start


TBS Vendetta

TBS Vendetta FPV Racer Review

Our top pick when it comes to ready to fly FPV racing drones is the TBS Vendetta. This (nearly) ready to fly racer has an incredible feature list and combines top specification components within a beautifully crafted and truly unique frame. Pop in a receiver, attach the arms and get flying; the manufacturers say from box to air will take you only 5 minutes. Let’s get into our TBS Vendetta review after this short video!

TBS Vendetta

Vendetta Specs:

  • FPV Camera – TBS ZeroZero 650 TVL, 1ms latency
  • Video Transmitter – 40 channel, 25mW – 800mW adjustable
  • HD/Recording Camera – Angled mounts for GoPro and RunCam/Mobius
  • ESC – TBS Powercube – 4x20A
  • Motors – Cobra CM2204/2300kV
  • Flight time (hover) – 6 minutes
  • Flight time (normal use) – expect around 3-4 minutes on a 1300mAh
  • Fully configurable via OSD
  • Weight (without battery) – 410 g

The Good:

  • Strong but lightweight carbon fibre body
  • Modular design
  • Replace crash-damaged parts quickly and without the need to solder
  • Configure settings using the OSD and your radio transmitter, no need for a PC

The Bad:

  • Expensive
  • Not friendly for beginners – you have no assistance in the form of GPS or level hold
  • Installation of receiver required
  • Not as much flexibility as a custom build

If you are considering splashing your cash on the Vendetta, then it is likely you have some FPV racing drone experience already. Experienced pilots may find this drone somewhat restrictive and for the price you could build one hell of a custom racing drone, but we understand that not everyone has the time, experience or inclination to do this. For your money you are getting a very polished product. TBS are known for their high-specification components and they have crammed the best of them into this incredible shell, what you are left with is the envy of all at the airfield who know what’s under the hood.

Cobra motors are some of the best known in the drone world because of their crazy amounts of power, so finding them on a RTF quad is unusual. They will have you screaming through the air and whizzing by trees, but you don’t have to be too concerned about crashes. The arms and shell are extremely tough and we expect they will take one hell of a beating without complaint. In the unlikely event you do manage to break an arm, these are easy to replace because of the MT30 connections, which include power (so no soldering). The arms are effectively hot-swappable and TBS suggest that you could carry around different pairs, to be prepared for any eventuality.

The installation of a receiver may seem like a daunting task for those with no experience, but in practice this is straightforward and just involves plugging the provided cable into your receiver. Make sure you check your receiver size before ordering, as space inside the drone is tight! Compact options like the popular D4R-II and D4R-SB from FrSky will fit, but you may struggle with anything bigger.

TBS Vendetta Review – The Verdict

The TBS Vendetta is a great package for those not wanting to put together a custom racing quad or who want an easy to configure and modify system. The speed and agility of this drone makes it a great racer or acrobat and it is very nice to see a ready to fly racer sporting parts that are normally reserved for high-specification custom builds. It utilises top of the line components whilst maintaining modular, repair friendly features that mean you will never be grounded for long. The price reflects this, so this drone may be out of the price range for anyone not taking the hobby seriously, but that’s only if you are lucky enough to find one in stock. If you do, act fast.


TBS Discovery

 

TBSMy TBS Discovery

Well, it took about a good month to get my TBS Discovery working, but it’s worth it.
It is my first drone (quadcopter) and perhaps will be the only, Definitely not.

TBS Discovery weight.

The TBS Discovery has an all up weight:1.85Kg but this all depends on the features you add to it.

Here is the build:

  • TBS Style Reptile 500 3K Carbon Fiber Quadcopter Multicopter Frame Kit FPV
  • 4 x 4X AGM MT2216 810KV Outrunner Motor. 2 x CW, 2 x CCW
  • 4 x 30A Brushless ESC SimonK
  • APM 2.8 Flight Controller
  • NEO-M8N GPS
  • Power Module XT-60 type
  • 3DR radio 433Mhz Data Transmission Module
  • MinimOSD
  • SJ4000 Camera
  • 5.8ghz Transmitter
  • FrSky V8FR-II 8-channel Receiver

TBS Discovery feedback about the design:

Its a great design and a well thought out layout. It flies extremely stable and forgiven I feel it needs a better undercarriage, as the ones on the legs are not great and do not given enough clearance, on take off and landing.
Also, would have liked to seen better options for a gimbal but this design floor has been overcome with my gimbal extension.

What would I have done differently?

I would have moved the 2 back arms further back and perhaps used the same angle that is used up front. This would have had two major positive impacts.
1- it would enable the possibility to use 11inch props further increasing efficiency and max output power.
2- it would have shifted the center of gravity to the center of the front and back props, because at the moment it is shifted towards the back, loading the back motors more, and causing when falling some oscillations, and when rising lower than maximum output power.
Option two, to this floor, would be to put the extended arms onto the TBS discovery allowing larger props.

Besides that, I really like the overall concept.

Now what I have done in my quad. First of all, I used 5.8GHz video transmitter, to avoid all interferences of neighbors WLANs and other 2.4GHz radio systems if flying with others… True range is better with 2.4GHz, but with tracking, 5.8GHz is well within the operating range of the quad.

However, I shifted the antenna rather high for 2 reasons:
1- 5.8GHz @ 600mW can cause a lot of interference on the long wires going around.
2- to avoid reflections and reduce the impact of the Quad on signal quality.
You loose in transportability, but gain a lot in video performance. I also use an antenna tracker for longer range missions, but with just goggles, I reach about 300-500m flying very low. With a 13dB flat panel RHCP, I still have reached the limits… I expect some 3-5km.

Components

Lens: I changed to a 2.8mm lens to have a little more FOV than a 3.6mm.
GOPRO: I don’t have a GOPRO as they are expensive and can get damage on Drones so went for the cheaper option of an SJ4000 the TBS Discovery doesn’t cater for a gimbal but I have designed and 3d printed a gimbal mount for it.

Battery: turnigy 5000mAh 15C, it fits like a glove and give 4000mAh effective capacity and weighs only 475g. At so point, I may fit a helicopter undercarriage that will give me clearance to carry a second battery for longer flight times.

Motors: I used AGM MT2216 810KV Outrunner Motor since at the time I ordering these were cheap and had good reviews I haven’t had a problem with them and not looking to upgrade them until they show signs of failing.

Top speed: 45mph

I used MiniOSD… yeah yeah I know what you all think, but I find it works reliably and has good support. It was a little tricky to get is working on this board, but not too complicated.

Total Battery time: I achieved 13-14min in this configuration.

Props: 10×4.5 if I extend the arms a may go with a larger prop.

Summery

All in all, I am very happy with it and the AMP controller which works very well in combination. I especially like the GPS mode if you are a beginner and for certain video captures.
I would highly recommend it to anyone who wants to make nice vids without props in view. it could have been a little bit more external OSD friendly, and center of gravity shifted more to center. I’m still working on the vibs, but once they are under control then the video can be captured at 1080p. However when at high speed, then you need to reduce the gain to reduce oscillations and get rid of jello effect.
But its compact and versatile, with great potential for making awesome vids.

A quadcopter, also called a quadrotor helicopter or quadrotor, Is a multirotor helicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft because their lift is generated by a set of rotors (vertically oriented propellers).

Quadcopters generally use two pairs of identical fixed pitched propellers; two clockwise (CW) and two counter-clockwise (CCW). These use independent variation of the speed of each rotor to achieve control. By changing the speed of each rotor it is possible to specifically generate a desired total thrust; to locate for the centre of thrust both laterally and longitudinally; and to create a desired total torque, or turning force.
