RC Guy....I used to use the hitec 2 channel radio and also the 2 ch radio that included a sliding switch for throttle. Nowadays, I fly radios with 2 sticks but only use the stick on the right for pitch and roll.
I think they call that "mode II".
Some guys [especially pylon racers] think that having pitch and roll on separate sticks allows more precise flying. I'll bet that's true...I've just never forced myself to relearn how to fly.
Andrew....I assumed the Blink was symmetric before I went on my little search for old build threads and was surprised to see a photo of what I thought were Blink ribs...that were semi-sym.
I do not recall where I saw that [could have dreamt it?]...but once gain I'm relieved to see that The Blink was fully symmetric.
