Hi i recently bought a sky surfer v3.got it 4m rcbazaar. My esc(30amp) and motor does not respond to throttle input, whereas all other servos respond.!! I tried caliberating esc.but wen i connect battery thers no beep/sound from esc.!! Wt should i do? How do i know wheter the esc or motor is faulty? Its my first rc plane.!!!

Check the throttle is inversed and put a servo on throttle channel to see if the output is coming or not

It is possible that the ESC connections to the motor have come off... Check the wires from ESC to motor by gently tugging it... possibly the bullet connectors are loose

Thnx a ton hangingtough, i reversed the throttle but same result.m contemplating checking the channel wit servo.but i dun hav bec.how do i power the rx if i add a servo to channel 3 ie throttle?

It was such a help rooster .i pulled d esc wires nd one wire seemd to be loose. I removed the esc nd will check wit a multimeter.but how do i reconnect esc to motor?
         A, B,  C wire of esc to which colour  (red, black, yellow) of motor.

Connect all the three wires and check the motor rotation ... In case you need to reverse the motor rotation.. Then interchange any two wires.

U mean we can connect regardless of any polarity.

There is no polarity for the 3 wires from esc to motor
