currently within the group of multirrotores are many different pricing options and different manufacturers, but today the launch of two phantom + vision is almost the best option that exists within the plug and play models, models phantom have been very famous for their reliability and easy operation in flight , a person without any type of learner experience may RC flying in minutes. The latest release of the two drone phantom + vision includes a very important feature for a professional video we want , this feature is a gimbal camera and 3-axis stabilized , this is a great feature to make truly stunning videos and photos. Similarly retains the feature of its predecessor, as the ability to fly up to 25 minutes of video transmission wifi. In my opinion the phantom model lacks little to attain perfection , which would be added together to the capacity for autonomous waypoint navigation . I think this would be a feature soon we will see in the line multirrotores DJI PHANTOM.


My experience in search of the ideal drone airframe

miércoles, 2 de abril de 2014

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





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.

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.

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.
