Old and Bold RC PILOT
Your explanation is quite good so I will not add boring science to the explanation.I totally agree with @Hai-Lee. As a beginner not to long ago, actually still am in many aspects, so much to learn. I kept building plane after plane on the RET crutch and found that even though it seemed mentally easier to fly, that once I stepped up to the bank and yank AET the control become so much more dynamic and real time. To level out a plane with the sticks, dihedral or not, using the rudder also turns the yaw of the plane which adds a new control factor to the equation. AET will level out a plane, again dihedral or not, as u input on the Tx without the yaw variable, what you put into it is what you get out of it, which makes what you see up in the air more real time real feel kinda situation. That's what I find with it anyway. If I am wrong in that explanation, @Hai-Lee please correct me, but I don't think I will ever go back to a RET again.
My Spitfire, a warbird which is supposed to be harder to fly then most of the other designs besides the 3D airframes, as an AET was one of the easiest planes for me to fly. It was my get comfortable/go to/first in the air before any other/work out the initial jitters kind of plane. Initially when I first built it, it took me over a month to even work up the nerves to maiden it. Then looking at it one day when I was looking to fly one of my Minis i decided I wasn't going to let my 22000 3s batteries just sit around and took it out. Flew a couple packs in my Mini Scout to get the game down, hesitantly powered up the Spit, and i will tell you that maiden flew better then any of the Minis I was already used to, which were all RET set up.
As far as the building goes bud I would say just watching a lot of FT vids while building, and not just the designated build vid for the plane you are constructing, really helped me. And then just doing it builds the confidence as well. Pro tip... make sure your cuts are clean using a sharp blade and your folds are square.
The Mini Scout was actually my first successful flights on one of my builds, so I built 2 of them. I since have also run through a Simple Scout as well at a 4 channel set up and it was a dream to fly as well. Do you have just Mini power packs or do you fly your slender deltas on standard packs? Because the larger planes fly better then the Minis.
As for RET models, there are quite a few EXPERIENCED pilots locally that refuse to fly, Maiden, or teach on, anything RET. When a student starts converting to RET their crash rate actually goes up markedly! They are told to fly the old 3 mistakes high because it can take a lot of air to save a model which goes into a Dutch Roll. Ailerons on the other hand take far far less altitude to correct and the control is far more predictable.
I still fly and teach RET but seriously it is a bit of a pain as I am always being asked to take control to save the bird!
If you can fly RET then ailerons will be so easy you will kick yourself for not making the transition earlier!
Have fun!
