sorry for the delay. but havent had much time.
anyway forget it. i fixed it already. i dont know exactly what i did right or wrong but now is working.
hehe. so thank you very much people!!!
bad thing is that from soldering and desoldering from the new 4 in 1 esc i dettached one of the copper pads for the motors… and i dont think i will be able to to use it anymore. luckly i had the old one, that worked perfectly.
