Custom Voice Events Setup on Spektrum radios

Spektrum radios, as many today's radios, have voice alerts which you can customise by your needs.

Switch based events

First type of voice events or alerts are switch based. It means that by changing position on any switch or even control sticks, you can have voice alert or event. That, for example, can be your Gear switch telling you about status of the gears or some other switch telling you in what flight mode you are, etc. It is very simple setup process that can be done in couple of minutes.

Time based events

Time based events are limited to telemetry data, so you need to have telemetry receiver and some sensors to create time based voice events. That can be very helpful, you can assign certain telemetry data to switch, and some other telemetry data to time based reports. Time based reports can be set up from 5 seconds up to 60 seconds. What that means ? It means that if you set your altitude data to 20 seconds, radio will alert you every 20 seconds with that data.

You can combi…

FT Simple Scout Snoopy Edition

When I saw this plane on FliteTest page I have said to myself that I have to make one.

Awesome looking plane, just like some WWI fighters. And of course, I had to add something....

I am not an FPV guy, I prefer watching the plane while it flays.

Whole plane is made from white depron boards and it was finished quite fast, within 4 afternoons of easy work. Since I use white depron, I have multiple choices of painting this nice bird. This time I have used standard red covering film (non transparent) to cover the wings and almost whole fuselage.

Procedure on how to cover depron with standard covering film is explained in one of my previous articles.

As I have mentioned , I am not an FPV fan, and that space is great for adding a pilot. Which one should I choose ?

Friend of mine has borrowed me his 3D printer and decision was made. Snoopy. And of course, Snoopy needs a machine gun too. Vickers machine gun from WW1 suits him just fine.

Nose of the airplane was a bit ugly for me, so i had to…

HJ Digital Servo Tester/ESC Consistency Tester

Well, everyone in RC hobby needs one.
This one has 4 outputs and if you use Digital servos, 2 digital modes of operation (and one analogue of course).
So no matter if you are testing servos or ESCs, this handy device will help you determine issues with your equipment .

Link to product :


This company publishes new products almost every 2 weeks, and I have received their new VTX which is loaded with new features.
Let's talk first about specifications. Mine came with RPSMA female antenna connector (there is a MMCX version too), standard 40 channels , 25mW/200mW/500mW/800mW power switchable and 7-24V input that provide 5V output for your camera. Weights only 7 grams without antenna and cable, and small enough to put it on any type of vehicle New feature is Smart Audio port which allows you to change channel band and frequency and even power output via your BetaFlight OSD controller (and radio of course). If you do not have that type of controller, you can change manually all parameters with button on the VTX. 7 segment LED display shows which band is in use , number of channel and power output mode. Another feature is PitStop mode. What is that ? Well, for FPV racers it is good thing, when you want to change channel frequency, you put it in pitStop mode. That mode tr…

H-King Junkers Ju-87B-2 Stuka 1400mm (55") ARF

This is ARF kit and demands some knowlege and a lot of patience.
So let's start.

First is the wing, I would suggest you that you read manual very carefuly, count those hinges, they are different for flaps and ailerons. Also, be careful with static flaps, flaps and ailerons since there is left and right side ones.
Test fit everything before gluing.

Hinges are glued with CA glue. Each slot is cut for particular hinge type, but as said before, test fit hinges before gluing them.

Control surface hinges are all the same and you can't miss there.
When glue dries, mount control surfaces to hinges using M2 macnine screws provided. Use loctite on your bolts and don't tight too much those bolts, control surfaces need to move easily.

I would suggest that at this time you insert servo extension leads in both wings and fix them with some masking tape.

Mounting landing gears is easy, I used 5 min epoxy for wooden blocks that come into landing gear cowling (manual says use CA, it's up…

AKK K33 40CH FPV Audio Video Transmitter

As with all AKK equipment received in past couple of months, this one comes well protected in the box.
What can you find in the box is the transmitter, standard stick antenna, connecting cables and short manual.

Transmitter itself has 2 buttons and 2 LED 7 segment displays which are really bright.
Weighting only 8.1 grams without antenna and cables it is suitable for any application like mini quad, RC airplane, flying wing etc.
Antenna connector is placed on the top of transmitter (there is a version with side antenna mount called K22) and it has standard 40 channels transmission divided into well known bands A,B,E,F and R.
Frequency chart is provided in the manual.
Changing band and frequency is really easy with provided 2 buttons on the side of the transmitter itself. One button changes band which is displayed on the first LED while second button changes frequency on that band and is displayed on the second LED display as a number from 1 to 8.
And that is it, select your preferred c…

AKK A5 FPV AIO split system

There are a lot of similar products you can find in various Chinese shops, I had one that is not split system couple of months ago and was not happy with it.

This little thing really surprised me. Why ?

Well, let's start.

Most of AIO systems are in one piece. This is split system meaning that VTX is separated from the camera.
Though non split systems are good for micro quads, if you are planing to use FPV on micro airplanes like UMX series from Parkzone, that could be the problem.
Those micro airplanes are very light and adding AIO FPV on them will change the CoG of that airplane, so flying will be almost impossible.
That is where this split system comes. You can put a camera on the nose and move VTX little further away to have correct CG on the plane.

Or maybe you want your camera to be inside canopy and VTX outside.

Another problem with system that are all in one piece might be that you would like to add OSD.
OSD comes in between of camera video signal and transmitter, and since…
