Ok, I need an engine controller and both of them have great advantages, but which is better suited for a daily driven FC3S rotary making 400hp? Does anyone have any person experience stories with either of these controllers? Thanks

 

e6x is cheaper, e11 does more. E6X is probably all you need.

 

on a 2 rotor the e6x is all you need.

 

E11 is a lot better, but there's a significant price increase.
If you can afford the E11, I would recommend that.
Full sequential is nice.
Also, the E11 has a LOT of "bell and whistles" that can help in tuning.

I just bought an E6X mainly due to financial reasons. I read the manual for both of them and while the E11 certainly has desirable options, I didn't have an additional $500-600 to spend, and certainly not if the E6X would do well. If you've got the money and don't have other important things (such as reliability mods for your 400 hp, bigger injectors, etc) to spend it on, then I say go for it, it might be worth it to you. But if that $500 or $600 might be better spent on even one truly important item, I say get the E6X. Its not something you will "regret" but the E11 is certainly gravy.
