some issues about RX and ESCs

Message Topic Search Topic Options Post Reply Create New Topic Printable Version

hi, this my first post

i'm interesting building a quadcopter and i'm beginner also,

i compiled a frame (x525), i placed a power distrubution board,

motors connected to ESCs and ESCs connected to dist.board.

all components ready and connected eachother

(4xturnigy 2217 Motors, 4x turnigy 30a esc,1x 5000mah3s lipo)

i completed programming ESCs also,

just control board not connected, i'll connect at last.

after this point i have some troubles

when i connect battery to dist. board, all ESCs playing a short melody and after all, all ESCs starting beeping delayed 1-2second,

my first question is it normal? because there is no signal from reciever or control board. or are there another problem.

second thing,

i'm not sure is rx binded to tx and i tried to bind, i started tx with bind mode (light flashing on tx module)

i connected cr8d reciever to ESC's bec(5V) during hold bind button on rx and power up from dist. board.

nothing happened on rx, there is no light, flash, smoke, smell... nothing (ESCs beeping ofcourse)

i tried connect bec to 1-8 slot

i tried connect bec without bind button

i tried connect bec reversed polarity on rx

nothing happened. There is no light, sound, blink...

maybe i messed up rx with reversed polarity or bec not giving voltage during beeping period.

what's you suggestions, please help me guys.

	These beeps are normal when no signal is present on input connector of the ESC. How did you program the ESC's? If using a programming card, did you have to use a separate battery to power the card? If not, the BEC was working and powering the card, so it should be able to power the receiver also. Fred

	i found problem, the problem is TX module. i gave my rx and tx module to my friend, ha have same environment, we bought together already. rx of him could bind tx module of him, my rx could bind to TX module of him, rx of him couldn't to bind my tx module, my rx couldn't bind to my tx module my tx module seems fine, i mean light is pure red when normal powerup tx. and light is blinking when during powerup in bind mode. i couldn't realize why is not working? i tried many times to change ID of tx module (hold bind button over 3sec of TX module) but it's not resolved. i have hope for TX module should work. do you have any idea or suggestion? Note: TX - Turnigy 9x and on PPM mode.
