" I would like to know what it is and how it is used in tricopters.
Pls some picures
Hi every one thank for the answers, ive made greate advances about the proyect.
Now I am wondering what electronic sistem shoud i add to the tricopter im thinking in drive it whit arduino using bluetooth or Wi-fi, making use of android.
It is posible to use the Laptop to pilot trougth wi-fi
How can i make that if fly alone ovoiding obstacles?????
Im uploading some photos and art states, incluiding:
*3d model first state
*second model with some upgrades and textures
*Distribution of engines and direction
I wish that you show me some propellers that give me better performance on the proyect.
Some Info about the arduino sistem that i sould use
The only EDF I am familiar with is 'E'lectric 'D'ucted 'F'an
Can you enlighten us on the other use of the EDF acronym?
Where did you see it and how was it used?
ah thats what i mean sorry, i was leavin the house an i wrote without information
Yeah thats what exactly i mean i was working on that proyect, but with a new design i will upload a photo from the 3d model i need some help with the engines, im not sure what is better for me.
Thanks, a lot to every one i get scared when i saw "EDF may be used to lower efficiency" am now a bit confused. But thanks for the answers.
I apreciate if some one help me with some choices for the proyect.
The proyect is about arduino and android, im working on the arduino one and im trying to decide if i can use a bluetooth or wi-fi. I upload the video of the 3d model
Again thanks for the help.....
Juan, nice looking 3D model. Your project sounds very interesting! I am new to UAV craft, and am looking to build something that can be flown both indoors and outdoors. I have not discovered technical information, and supported by careful experiments ( not this kind !!! ), that compares real configurations/designs of tricopters, quadcopters, hexacopters and other multirotor craft. Enough to know if a specific design can lift a ___ gram payload for ___ time duration. More payload than can be lifted with smaller, safer, less expensive craft (Ladybird, V929, hybrid) as mentioned on this. The kind of consolidated information that I seek may exist, but I have not found it. However, this may help you (although it does not appear to include propellers in an EDF design). This may provide enough information for a tricopter design, even if not using EDFs. Good luck on your project! Maybe someone else on DIY Drones can offer more information.
@Juan, you may want to tune in to this thread.
That's not true. An EDF has a higher efficiency then a prop of the SAME SIZE.
EDF's are not in generally good for multicopters (tri, quad, hexa and so on). Why? Put it simple way: their efficiency is based on small propellers that accelerates air on "windtunnel" as much as they can. Eg creating a lot of thrust.
Multicopter ideology is based on really fast and accurate control of airflow. Due the design EDF systems they are not suitable to fly multicopters. Yes you can make a multicopter to fly with them but flying will always be a bit "springy". This is purely because of amount of they move air. You just cannot make EDF to speed up/slow down fast enough to make them accurate on multicopter use.
If you build complex vains/valve system to control direction of thrust and speed of it, yes you can do it accurately but cost will be a lot higher/heavier than with normal lowish RPM brushless motors and big propellers.
I must be doing something wrong, I have built several and find that they fly very well. They are more stable and actually very smooth.
Whoa that quad sounds like crying animals, why??
A problem with the design, im already scared if my proyect sounds worst
But what do you think about use the external cilinder to protect the propellers i mean, not use the EDF´s, replace them with propellers and make an adaptation to use how i say before an external cilinder to pertect em.
Is that a more suitable idea?
