No, there is NO opening of the TX case involved.

The right stick controls pitch and roll while the left stick controls throttle and rudder...

Yours seems to be working just fine.

You need to adjust the switches on the transmitter. These switches reverse the direction of the signal to the servos.

DO NOT touch the settings for channel 3 and 4, as you have established they are already correct.


First what sushi2me is not correct:

Here is how things are normally set up...

Channel 1 = ailerons

Channel 2 = ELEVATOR

Channel 3 = speed control/power = throttle

Channel 4 = RUDDER


The EF2000 uses ELEVON mixing which is very different...

So the channels are used like this...

Channel 1 = LEFT WING SERVO

Channel 2 = RIGHT WING SERVO

Channel 3 = speed control/power = throttle

Channel 4 = RUDDER


The transmitter then utilizes built in "V-Tail or Elevon" mixing to make the two wing control surfaces behave as they should.

If you find that you can ALMOST get everything right, but that say pull the right stick back towards you causes both wing control surfaces ( called ELEVONS ) to move DOWN ( which is reversed ), then EXCHANGE the plugs ON THE PLANE going from the wing servos... and then flip BOTH of the REV ( reversal ) switches for Channel 1 and Channel 2 on the TRANSMITTER.

Nothing needs to be opened or disassembled, other than getting at the receiver and connectors which is easy to do WITHOUT breaking or dismantling anything.

That's it!
