It is a folding 6 rotor helicopter, inspired in X6 helicopter.i would like to build in polyethylene technical plastic, it is light, shock resistant and easy to work with my cnc mill.propellers are in a circle of 500mm diameter, i think best option in order to use standard RC parts is to use 6 x 12" counter rotating propellers.3 (counter rotating) propeller of 12" have an 8% more surface than 4 propellers of 10" (like typical quadrotors)Probably 14" propellers are better in order to get more performance but i think is not possible to find very low Kv motors with the necessary low power and low weight.Any idea are welcome!jlcortexnmine.com
Nice to know!
Talking about this project, what about blade sizing? Why is lower blade smaller than upper one? Is it because of the air-flow generated by the upper one that i need a smaller one at the bottom?
Do you know about efficiency vs rotor distance (talking about coaxial)? I read that if the distance between the 2 rotors (talking about coaxials) is 17.5% of rotor radius you get near double efficiency, true?
Thanks again, and apologize my english
Thank you very much!
I already found this one: http://aeroquad.info/bin/view (that seems to be the evolution)
but it is a quad rotor project and i'd like to build a tri coaxial rotor copter.
i will look better into it and come back when i bit more skilled
Do you know which model of copter will be better? tri / four / six rotos?
Anyone with some good link about fixed pitch coaxial application? (of course interested in math model)
Thanks
Hello,
I'm interested in building an UAV like this. Can someone point me to some good projects? I' looking for:
-Reading to start from (basic concepts and more)
-Technical details such as parts to use (engines, blades, controllers...)
-MATH MODEL!!!
I'm computer science's student and i'm going to develop this as thesis so i need a lot of help! :)
Thanks
Yeah this does remind me of the X6 but it's better because the camera design seems to be integrated into the airframe vs. hanging from the underside. I read this thread http://diydrones.com/profiles/blogs/bidireccional-rc-transmitter?id... and I think both your idea and the other could greatly compliment each other. What do you think? I wrote this in another thread
I wish guys like you (guys with the technical know how) could work together, design and build a modular UAV. Have the MCU/DSP and all the sensors on the main board. Have the motor controllers separate from the main board so anyone can use different size motors (scalability). One can build a 10inch wide quad or tri- rotor or a 3 or 4 foot wide version.
Another option is a board with everything except the MCU/DSP/CPU board. This should include the sensors, servo controllers, FPGA et.c that can be controlled over USB by a gumstix module or some other powerful module (or even a pico ITX motherboard). Coupled with a controller like your idea. Anyone can make anything out of it. I'm sure the software developers out here can cook up something modular to handle all the stuff.
Using an even number of motors (especially 4 or 8) it is easy to see how to control such a 'copter as they work in pairs and counter rotate. I have a problem with 6motors. Can you tell me how you control pitch, yaw and roll?

Here´s mine, by the way!
