Hi,

I was wondering if I could get some assistance with my controller. I had received an 2.4Ghz EF2000 Brushless Radio Controlled EDF R/C Jet 100% RTF Black Version model for christmas and when I went to test out the controller the left stick worked ok for throttle and rudder but the right stick was backwards with up/down = left/right and vice versa.

Do I need to open the case to change something or is this and issue where I would need a replacement?

Thank you in advance for your assistance in this matter

Normally 4-channel planes are set up as follows on the receiver:

Channel 1 = ailerons

Channel 2 = rudder

Channel 3 = speed control/power = throttle

Channel 4 = elevator = up & down

Anyway, I believe that is correct for MOST 4 Channel transmitter - receiver setups!

On a Mode 2 transmitter, which is one where the throttle is on the left stick up and down and rudder is also on the left stick left & right (like yours).

Your problem is, as you say, "...right stick was backwards with up/down = left/right" - this is NOT something where you can reverse the operation with the servo reverse on the transmitter, this is where you have to switch the appropriate leads on the receiver! Simply unplug the appropriate leads and switch them = plug them in where they belong!

If it doesn't work, try again until you get the correct operation!

Hope this helps,


Happy New Year,

Your radio should have either hard switches or programming selectable "servo reverse" settings. Simply find the Elevator and Aileron servo reverse switches or program and change these two settings. You should then be good to go.

While the above posts are correct, the Delta wing configuration of the EF2000 is a bit strange.

If you find that no matter what you do ONE of the directions does not work correctly:

e.g. You can get the aileron function correct, but the elevator is backward - OR - you can get the elevator function correct but the ailerons are backwards....

Then REVERSE the channels by unpluggined the right elevon from the receiver and plugging it into the socket for the LEFT elevon instead.

THEN adjust the "Reverse" switches as needed.

I had EXACTLY the same problem as you are having with my EF2000 and this fixed it. At first I feared that something was wrong with the receiver, or transmitter.

A bit of trial and error and everything was right. No problems what-so-ever.

Also remember that with the sticks centered, you want the elevons deflected UP about 4mm...

That means the trailing edge of the moveable control surface is 4mm ABOVE the upper trailing edge of the rear of the wing.

That is where you want things when the stick is centered.

The plane WILL roll when you fly it ( which you must compensate for ) until you trim it out.

Properly trimmed one elevon will be about 7mm up and the other about 4mm up.

BTW: This plane lands very nicely, with a nose up attitude.

wow, thanks for the fast response!

I wasnt sure about opening up the case on the TX if it would void some warranty or prevent a return if needed.

I will try what opjose suggested and let you know how it went.

once again, thank you all for your help!

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!

Thanks again for the help guys. I got it working fine now, I just had to swap the receiver wires.

One thing that confuses me is that the TX wont work right with the FMS software. I dont see a setting anywhere for a delta type wing config. Has anyone run into this problem?

With simulation program input mixing is done via the software.

You normally have to set the TX to treat the inputs much like a standard wing plane.

Because you have an EF2000 with elevons, this conflicts with what FMS expects.

Switching back and forth will also likely put your EF2000 out of trim during flight.


If you will not be flying for a while, then set the TX for normal aircraft types, and use that for FMS.

Once you are flying I'd suggest using another TX for FMS. You can buy a suitable PC unit for about $20.00 from Nitroplanes.
