RE: Need help setting up receiver in EasyStar
Lets have a go at this - its hard when I don't know the colors of wires YOU have. From photos I've seen the Cirrus Rx has the channels labelled on its upper face (1, 2, 3, 4 or batt). From top to bottom the three pins for each channel are (probably) negative, positive, signal.
The ESC should have two wires labelled "to motor" from one end (?red +, white or black -) , and at the other end, two wires labelled "to battery" (?red +, white or black -), plus the three wire lead to the Rx (?brown -, red +, yellow signal). [the ESC will almost certainly have BEC (Battery Eliminator Circuit capability) so you do not need a separate receiver battery].
Connect the two wires from the 400 motor to the two "to motor" wires from the ESC. Connect the 3-wire lead from the ESC to the Rx into Channel 3 (throttle) with the signal wire (?yellow) down. Connect your 3-wire rudder servo lead (signal wire again down) into Channel 1 on the Rx, and the elevator lead into Channel 2.
ONLY WHEN YOU ARE READY TO TRY THE SYSTEM, turn your Tx on FIRST, THEN connect the battery, with correct polarity, to the "to battery" lead on the ESC.
Let us know how this goes!
Cheers, Phil
