I cant figure out how to make my canards move with rudder/elevator. I converted my f35 v2 to fly like a J20, for better high alpha. I'm trying to pull it off with just five servos, the top diagram is my current setup but I don't get any elevator movement for obvious reasons. I think the bottom diagram would work but using six servos which i don't want to do. Can I make it work with only one servo for the canards or do I need two?IMAG0545.jpg IMAG0546.jpg IMAG0547.jpg

Jeanaky, Can you do radio mixing? If so let me know. What kind of radio? The set up for canards is easy with radio mixing, hard with mixers. Actually, you don't need a mixer- just use a splitter on elevator channel and connect one end to canard servo and one end to elevon mixer. But,you cannot limit the movement of the canards this way. If you read through the forum you see a lot of guys having problems once the canards start moving up and blocking airflow to the wing. Anyway, You do a standard elevon mix and link the elevons and ailerons. if not, here's the manual way:
Aileron servo
> mixer <
Elevator < servo
canard servo
Can you see how the > are working?
But this will cause the canard to move up also, which is not good. So, its better to do a radio mix on canards on an aux channel which disables the upward movement.

FYI, Jeanaky, I made a profile Mig 1.44 plan that the J20 was based on. Very easy build and excellent high alpha. Plus, only 4 servos.

Oh, and one more thing. If you want to have a stationary canard, you can simply put the servo on the gear channel and when you flip the gear switch it will assume an angle. That angle should be the the angle that best routes air over the leading edge of the wing not an angle parallel to the ground. You would not need a mixer.

I have the fly sky th9x, its capable of mixing, I just use mixers but I'm stuck now. I read the forums but no one has an actual how to video on how to connect the servos to the receiver using mixers or actually mixing through a radio.

What you just explained, will it give me elevator on the canards and spoilerons when i hit the switch?

The first diagram will give you canard movement all the time. Now that I know what radio you have, I can tell you how to mix it on the radio. I have the 9x which is the same. Tonight I'll check it out. But, almost a year ago I think I listed my settings on the j20 thread. I'll look...

Thanks appreciate it, the radio is a little confusing.

Yes it is, but at some point you will see that it all clicks and then you become the mix master!

This is my set up. I have one servo in the elevator channel and one in the aileron channel on the rx. Depending on the orientation of your servos, you may need to have a negative value where I have a positive or vise versa.
Elevon mix :

This shows you the elevon mix in the radio. Notice you are setting the aileron and elevator throws separately. If you see the elevons moving up when they should go down, change the value from negative to positive. Or positive to negative. You can also limit the throws by setting a value at 50 or 70, etc.
For canards I plug the canard servo into aux 1. And do this:

So, i have the master as elevator, slave as aux 1, upward movement as zero (i never move canards up) and the downward movement at around 40 or 50. On this menu its set at 100. Finally I have it set to work on the 1st setting on the 3 position switch.
All these mixes need to be active or set to Act in the first line. Inh means inhibit and you'll get no movement. For rudders I would just use a splitter and don't worry about Vtail mixing.
Let me know if you have any questions!
