Beginners Guide Part 4 - Electric Motors

Image
Choosing the motor We have come to one of the most important parts of every RC model, which is a main engine drive.
About this topic it can be written very much , because, indeed, there is a lot of details about the main drive, I will try to keep as much on the most basics that can satisfy the absolute beginner without being overwhelmed with the amount of data and options choosing a motor.

We divide the engine drives into two categories: internal combustion engines and electric engines.

Nowadays, electric motors with their efficiency and price are mostly the first choice for beginners, so I'll base this topic onto them.

Electric motors
Electric motors are divided into several categories: The basic division is based on brushed and brushless motors. Brushed motors are of the older generation they wear and have the need to replace the brushes from time to time. Also they have less efficiency than brushless motors. By choosing the type of motor also depends choice of ESC (the brushed…

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

Image
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

Image
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

Image
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…

AKK CA20 camera and TS5828 VTX

Image
Let's try something new.

I just got AKK CA20 camera and TS5823 VTX at a unbelievable price (camera is 20$ and VTX 10$).



My expectations for such low cost camera was not big, but this little thing surprised me with OSD and bunch of features (some of them I still do not understand well). 
With the camera you also receive a bunch of connecting cables and one with small controller for setting the camera features (a lot of them)-

Manual is really basic, and that is the only minus for this product. I would love to see better manual with explanation of all features that camera provides.

Lightweight camera (12.4 grams only) can operate from 5V up to 22V (so you can take power even from your receiver) and has an excellent picture and nice colors .
It is 600 TVL NTSC standard and manufacturer claims that there is 1/3" SONY SUPER HAD II CCD,Nextchip 2040 DSP in it.
According to quality of picture, it sure is.

How to cover foam airplane with standard covering film

Image
I have heard that people are using standard balsa covering film to cover foamies and I had to try it.
And it really is very good solution. Gives the model some stiffness and if you use different colours, you don't have to paint it.
I don't have modellers covering iron, but use standard iron that every house has. Just be sure to set it to synthetic, which is approximate temperature good for covering depron and balsa parts.
But I suggest you to test first on some scrap piece of foam. Temperature too high will melt depron and foam and shrink covering film too much.
Usually I cover only control surfaces with covering film, and sometimes whole airplane.



How to setup dual ailerons and flaperons with Spektrum DX6 DX7 DX8 DX9 DX18 radio

Image
Easy setting up ailerons in three different ways with Spektrum radio explained. Each way depends on your airplane setup and each way has its own pluses and minuses.
If you get stuck, just ask in comments and I will respond as soon as I can.


Spektrum DX6 DX7 DX8 DX9 DX18 elevon setup / delta wing setup

Image
Setting up a delta or elevon mixing on Spektrum radios are very easy. It can be confused where to use ELEVON or ELEVON-B mixing, and this video describes the case on how to setup Spektrum DX6 DX7 DX8 DX9 DX18 elevon mixing.
If you can't get proper control surface movement by ether of 2 elevon mixings, just switch servo connections on receiver and try this procedure again.
