I think it is not, because ES2 has ailerons. Here you can decide to use 2 channels for ailerons, or one with "y" cable, etc....
I own a ES2 also. We can share parameters if you would like, but i had many other kind of problems, like rf noise etc, so i am not ready yet. My ES2 did fly more than 20 hours, but not yet perfect.
Where are you now? :)
Hi can you share your parameters with me?
