My experience in search of the ideal drone airframe



My experience with the drone is almost from the birth of diydrones, I began to experience the different versions of APM during experimentation I embarked on the search for an ideal to be used as platform for UAV airframe photogrammetry, in attempting this Search passes through many platforms for more than 3 years, but each platform had its pros and cons. within platforms are experienced with APM, diamon 2500, fpv raptor, skywalker 1700 and 1900, X8, X5, RVJET, CONDOR. more and more models. Here I present some of my videos and experiences:
skywalker 1700 and 1900





X8



X5


CONDOR


RVJET


all models described above are manufactured in EPO (foam) and I found the common denominator is that the foam deteriorates very rapidly when continuous operations are performed in harsh environments (in my case I operate in tropical Colombia). most previous models do not exceed 1 hour flight on board carrying payload of 300 grams. in the case of the X8 can carry more than 300 grams and fly more than one hour but its launch hand becomes complicated.
due to previous experience decided my own drone airframe manufactures, I have a degree in aeronautical engineering. and possess knowledge in aircraft design, so I started to do different tests to achieve the ideal airframe for photogrammetry.
 requirements propuese me I was the following:
- Must be constructed in composite materials: Kevlar, Carbon fiber, 
-Must be able to fly 1.5 hours carrying a payload of 300 grams 
-Should have the facility to be launched by hand. without danger of cutting the propeller in the hands 
-Must be completely disassembled for easy transport 
- Must withstand landings in difficult and hostile areas 
-Not exceed the maximum take-off weight of 3000 g

-have the ability to not enter stall at low speeds (spin)
Here I present a photographic sequence of the evolution of the different models to reach the most optimal.




















and finally this is the final prototype that meets the viewing requirements

the biggest drawback is its cost of production, which is why tube to abandon the project for more than 3 months, will I drained the budget for the completion of the first prototype. Today three months after it finished and I'm doing flight tests. later I'll upload the videos of the tests.

CAMERA 10 X ZOOM DRONE


After a year of having purchased the camera FH 10 with 10x zoom, the first experiences were poor due to the lack of a system of stabilization.
then decided dusting the camera again and stabilize with AMP 2.5. using the PAN and TIL my RVJET, to install it sideways. in my skywalker 1900. the camera has stabilization in the ROLL axis, the flight height is 300 meters and the loiter radius is 200 meters.

Project news

I perform the checks in 2.72 firmware for APM 2.5, and resutados are excellent. This firmware ensures greater accuracy in navigation with windy conditions. its sitonizacion and tuning is also easier. this serivira for the x5 has a comportameinto in flight smoother and precise planned missions.

Here are some examples of navigation


yellow line represents the theoretical route of the mission, and the blue line represents the actual path that the drone x5 realize, as you can see the comparison of the theoretical with the real is very close.

DRONE UAV X5 (in English)


hello everyone.
today I want to say that the first UAV DRONE, we will build is the X5 flying wing, during the next 30 days I'll upload contruccion instructions and system configuration.





x5 with all equipment on board, ready to flight test.

-APM 2.5
-BAT 2 x 2500 mha
-photographic camera
-telemetry 900mhz

1250 grams total weight




in this video we see the results we can achieve with the instructions that will be implemented within 30 days step by step





the parts needed to build the X5 DRONE / UAV




1- Airframe X5 with servos




2- Autopilot APM 2.5 with  GPS


3-Telemetry Kit 

option 1


3DR


option 2

XTend 900


4- motor 1000-1400 kv and 350 watts-450 watts


recommended  Hacker A30-12M V2






5- speed controller 40 - 50 Amp.


6- Radio with more than 6 channels.
radio options there are many options on the market, I specifically use Futaba 12FG



7-Propeller apc 9x6







configuration instructions


1- download the last file Mission Planner




2- install mission planner

This presentation should be installed and executed after




3- connect APM 2.5  to PC.



4- install the latest firmware on the APM 2.5


The following image shows the specific values ​​of the PID for the wing X5 for firmware 2.71




download the file




5- set your radio to the option to fly wing.

a- elevator exponential  -30
b- aileron exponential    -20





6- adjusting the movement of the servo as shown below. 13 mm up and down




flight test











below show the x5 and another project I'm working on that later I'll post more information about it.
