I did a search, but couldn't find exactly what I was looking for.

I'm getting my first ever plane that has elevons and I was wondering how hard the programming is for it. I looked through my manual, and it seems pretty simple. I just have no idea what values I need to use and what exactly they mean. Is there a resource (other than trial and error) that explains this?

I'm guessing that the percentages for aileron and elevator control how far the control surface moves as compared to each other (or each other's inputs). I have no idea what "differential" is referring to.
Any help would be appreciated...

Hi deli conker
it couldn't be simpler.
If you have the model already the most practical thing is to try.
Go into elevon programming on your radio and turn the model on. Then start playing with the percentages and move the control stick around.

Different models have different control throws so i can't tell you a precise percentage.
Differential is the difference between the amount of up and of down travel of the aileron.
Keep it equal for simplicity or decrease the down travel

I will cover the obvious.

Get your servos centered mechancially first.
Then do any fine adjustment using our subtrim menu
Then go to the elevon menus to set your elevon throws.

Hope that helps.

The plane should be here today. I've already downloaded and read (and re-read) the manual, and it really says nothing about the normal throws for it. Here's the manual...

Let me ask this question, what do the percentages actually refer to? When it says 50% elevator, does that mean that the elevator stick controls 50% of the total throw? Do the aileron and elevator have to add up to 100% or are they independent and I have to be really careful not to all any "over" throw?

Just build the plane, install the servos.
Then connect all the servos to your reciever . turn the radio on . install the flight battery .
the servos should center. then turn every thing off.
link the control rods and hardware on the servos making sure that the control surfaces are flat.
now go to the elevon programming on the radio with the plane ON.
go to the ELE2 setting and pull the elevator stick full down. set the percentage to the maximum MECHANICAL throw the plane has.
Do the SAME for ELE1. i am not sure the direction of movement. you will have to play with that a bit.

Then do the same for AIL1 and AIL2 but this time playing with the aileron stick while changing percentages.

You have to use your plane as a point of reference for all this programming.


REMEMBER to set the maximum control throw on end point adjustment before all this.


Hope this helps

Safe flights and landings!!

Hi Deli can it be a Turkish nick?
The percentage means full servo travel to one side(about 30-40 deg) if you choose to reduce of that 100 % means similiar reducing of that servo throw.Especially useful to adjust of carb throttle arm travel between full and idling without stress of servo.

I maidened that plane about an hour ago. Aside from the fact that the stock brushed motor isn't worth anything, it flew ok. My settings are as follows...

aileron +50%
elevator +50%
differential +0%

These are the defaults. I did have to reverse the servos though in programming for proper functionality. Like I said earlier, much ado about nothing. But I certainly appreciate all the responses. It's good to know that if it was more detailed than this, that I could get a little help (especially now that the local source of knowledge no longer exists).

At this point, I am shopping for a brusless setup for it as it is severely underpowered. I started a thread on it (in case anybody has any suggestions) to keep the board a little cleaner.
