Title: Consultation for quadcopter
Post by: STAVAN on January 20, 2014, 03:33:28 PM
hello
this is stavan desai from gujarat. I needed your help as my final year project in engineering is based on quadcopter. We have finalised a list of products that would assemble up to form a quad but we are not sure if this is going to work rather will fly. Can you suggest us few things if we are incorrect anywhere? Here is a list of products we are enfolding. This is an incomplete list.We are going to add up the transmitter-receiver combo but if any other thing is to be added kindly guide us.
Hoping for a quick reponse from you.
Thanking you.

Im not an expert here but I would recommend to choose a high discharge rated battery .....20c discharge is not good enough.

i think you should go for any battery above 35 c discharge...


good luck with your project......and show us some pics too.... :thumbsup:

Some points to keep in mind while buying parts for a quad:
:The total thrust of the motors should be atleast double of the final targeted weight of the quad.
:The total discharge rate of the battery (C rating * mAh/1000) should be more than the max amp draw of the motors put together.
:Buy atleast one spare motor and esc pair.

You might also look at the multistar multirotor escs and the afro escs.

:iagree:

firstly decide on a frame as it is a major weight contributor.  ;)

just a few points. 5000mah battery is heavy and will add to power consumption rate.
instead you can go for two smaller batteries.
if you are targeting for a quad over 2kg then i think a 4s will do a better job or you will need to increase the size of the propeller to either 11 or go for 12 inches. a quad of that weight will start hovering at 40-50% throttle with 10*4.7 props.  :-\
also i'm saying this because i don't know what you're going to use it for... but the JST to 3x2mm bullet connector is designed to work with a 10Amp multistar ESC.
