I started to search for parts for a quadrocopter which could be used to race and do some |
|
|
|
freestyle moves. |
|
|
|
|
|

Here you can view the.. latest projects i've started. |

Since for me also the assembly is new and I had the feeling that this quad will also be |
|
|
|
likely to be damaged I wanted to build it with seperate components. Also its more fun that way. |
|
|
|
|
|
|
|
Since I did not want to have a huge quad I wanted to hit the 250g Law limit for the assembly. |
|
|
|
In such a case I would not even be forces to add a burn resistent name tag to the quad, which I |
|
|
|
would anyway recomend if it could be lost. |
|
|
|
|
|
|
|
After some search i found the [Diatone quad frame GT M3](https://www.banggood.com/Diatone-2018-GT-M3-130mm-Normal-X-FPV-Racing-Frame-Kit-RC-Drone-3mm-Arm-p-1257062.html) prity aplealing since they have a aluminum cage for the pcb stack and a 3mm carbon plate which is robust enought for a beginner. |

|
|
|
The following motors where selected by taking the recomendations of the frame into account: |
|
|
|
motorsize 1408 |
|
|
|
motorr 4000KV |
|
|
|
|
|
|
|
The motor size of brushless motors for quadrocpters are regulary indicated by a 4-digit number |
|
|
|
The first two digits represent the stator width or diameter while the second ones represent the hight. |
|
|
|
The values types are in mm |
|
|
|
|
|
|
|
In general the motor size have quite a infulence of the flight caracteristics. |
|
|
|
A taller motor most likely result in more power at the upper Throttle/RPM and a wider motor |
|
|
|
would result in a higher torque at low throttle. |
|
|
|
|
|
|
|
Since i wanted to use motors with a actual datasheet or at least a messurement how much amps |
|
|
|
would be drawn by them with a certain propellor i took the [T-Motor F20II F20 II 1408 3750KV](https://www.banggood.com/T-Motor-F20II-F20-II-1406-3750KV-Brushless-Motor-2-4S-For-130-140-150-FPV-Racing-Frame-p-1154351.html) |

At this point the Motors and Frame where clear. The next step was to choose a propellor type. |
|
|
|
For this I selected a tri bladed one with close to the 3040 size. The size for |
