What wires go where from Plane (mig-29) to receiver?

Just got a Mig-29 EDF from HC-Hobby. Instructions don't show what wires go to what terminals on the receiver that goes in the belly of the plane. I have found out which wires are from the battery but have no idea what spot to plug them into. None of the wires have any labels. The receiver has spaces 1 through 6 for wires to plug into but I have no way of knowing what goes where. Any help is greatly appreciated. Thanks.

How much RC experience do you have? EDF jets are not a good choice for a first plane.

The reciever input should be:
1 - ailerons
2 - elevator
3 - throttle
4 - rudder
5 - retracts
6 - flaps

Good luck, get us some video of your first flight.

Which number gets the power from battery? The Mig-29 from HC-hobby only has four connectors that come out of the plane. The one with the power has more wires going to the connector than the other control wires. I know that the receiver must have electric current going to it to be able to work, so which number of 1 to 6 gets the power from the battery? Sorry if this sounds dumb; but a wiring diagram or matching lables on the wiring should have come with the plane. Thanks for any help. Oh the plane is my son's and he has a little experiance but is frustraited with the wiring issue and upset with the manufacturer.

If you can post a photo of the connections it would really help. Again this is a rather advanced model.

The receiver get's it power through the connector that runs from the speed control to the throttle channel (3).

Here is a typical wiring diagram.

Please pay attention to SAFETY
Keep fingers away from moving parts at all times!
Motors rated at 4300 rpm per volt x 12 = 51,600 rpm's.
First, Transmitter on, THEN connect battery.
Disconnect battery, Last Transmitter off.

Some folks have a thread open on this jet:
http://www.rcgroups.com/forums/showthread.php?t=982744
Here is a link to a vendor site
http://www.xenonproject.com/rc-airpl...hz-p-7863.html

This Jet has 3 servos and 2 ESCs. I suspect the ESCs are joined by a "Y" cable.
The four connectors each have three wires, black, red, white (maybe orange).
Black is minus, red is battery, white (orange) is signal.
On your receiver's right should be the channel pins.
If the pins point up, the left-most pin goes to the connector's black wire, middle is red, right-most is white signal
If the pins point horizontally out the end of the receiver, rotate the unit till the pins point up, the previous sentence should apply.

Sometimes, the pins are bass ackwards! see jpg example (below), and carry-on

one connector is for (pilot's) right horizontal stabilizer receiver channel 1
one connector is for nose wheel steering, goes to receiver channel 2
one connector is from the ESCs receiver channel 3
one connector is for (pilot's) left horizontal stabilizer receiver channel 6

Battery compartment? Under the cockpit canopy which is held on by magnets.

If you have a volt meter, you can discover which connector is the throttle.
(If not, skip down to the sentence beginning with "Plug").
Connect the battery.
With the voltmeter measure between black and red of each connector.
When you find 5 volts DC, label that lead "channel 3".
(5 volts comes from the ESCs, and provides power to the receiver and servos).
Disconnect the battery.

No voltmeter?
Plug-in one connector to the receiver's channel 3.

(Transmitter left stick is channels 3 and 4)
Stick movement back to front is throttle (channel 3) start with stick all the way back.

Someone needs to hold the jet on the ground by the nose and wing (If the motors start, you don't want it going anywhere).

Turn-on the transmitter.
Connect the battery.

Push the stick forward, looking for motor activity. Pull the throttle back.
No activity?
un-plug the connector and plug the next connector into channel 3. Repeat.
When the motors respond, leave that connector in channel 3, label.
(now, there's power to the receiver)

Plug one of the 3 remaining connectors into channel 2 (transmitter right stick)
This stick is "spring centered" push forward looking for servo activity.
Label the lead and move to the next connector, repeat.

Disconnect the battery, then turn-off the transmitter.
Re-arrange the connectors in their (now) proper order of channels

Hold the plane
(left throttle back) Turn on the transmitter
Connect the battery
Right stick should move the tail surfaces and nose wheel
Left stick should operate the motors.
Disconnect the battery
Turn-off the transmitter.

Thanks everyone. Great help. We have it going and have checked all controls. All is well. Now if we get some good weather, snowing yesterday and still snowing this morning.
