Awesome work! I've been planning to build a small quad, but kept getting hung up on what props to use and stuff like that. Thanks to you, I have all I need to move forward. I am planning on making a few changes in my design though. I'll have to post something when I get that built.

I do have a question for you. I notice that your quads all have a fairly proportional prop-size/prop-spacing ratio. How important is that? Several of the quads I've built flew a much tighter configuration (one was 10" props with only 1" clearance between the blades.) most of mine are spaced out a little more than that. Is there some ideal there? I guess, asking the question another way, if you were to build the same tiny quad with larger props mounted closer together (so the outer dimensions of the craft stayed the same) how do you think that would affect flight performance?

Oh yeah, one more thing, how much can your tiny quad payload? Thanks!! You're my hero!

I'm going to try these ones in couple of weeks:

MY12ABEC Mystery 12A Brushless Speed Controller * 4
T1811-1800 Turnigy 1811 Brushless Indoor Motor 1800kv  * 4

and 6x3 props.

Only near suitable from HK, some Sainta rush there, messy shipping.

@Theodor, you are right, thanks

@Michael, I have tested this platform with 5x3 props and even 6x3 (with 2S batt)

I don´t know if there is an optimun ratio but my experience is that if you use too much prop spacing (big arms) quads are more slow in response (and a lot less responsive in yaw!!). Short arms make quads more responsive and probably more fun for RC, but if your clearance between props is too low this could decrease performance.

With respect to payload I have flight with 40grams without problems... I tested a 100gram payload and could fly but is not recommended.

One thing that is sort of not clear is how the motors are mounted. Does the bottom-shaft portion of the motor just sit on the hole in the rubber mount in a tight fit? (Picture 12 in the document)

One Question Jose Julio, what´s the central part you used? i ´ve bought on decathlon 3 kits (4,6 and 8mm), and i can´t find what´s the part you used. I´ve one that seems similar (flexible) but´s it´s a lit bigger than the tube.

 

Una preguntita, cuál es la pieza central que has usado? me he comprado los 3 pack en decathlon (4,6 y 8mm) pero no puedo encontrar cual es la pieza exacta que has usado, hay una parecida( es como un tubo flexible) pero el diametro del agujero es un poco más grande que el tubo de 4.

 

Bye & Salu2

Oscar, you don´t need the 8mm kit. The piece you are talking about cames with the 4mm kit ant it is like  a "T". Jose Julio cut the "T" so actually it looks like a small and simple 4mm inner diameter tube .

Comment by Oscar Rosillo on December 13, 2010 at 7:44am

Mmm i´ve already used that 4mm T, just trying, but i haven´t cut the T . I´ve bought the 8mm kit to use with leftover pieces from 6mm kit to make a second a second/bigger frame, but some pieces from 8mm kit are different.

Bye,

Hi Jose Julio,

This is a great design - thank you for sharing. After a month of waiting now all parts have arrived and I will try to assemble it over the holidays.One question though: There have been some software updates like "http://diydrones.com/profiles/blogs/arducopter-ng-taken-over-by" - which software would you recommend to use at this point in time?

Thank you

 

Ralph
