Anyhow, got mine today and threw it on. Very easy to do... just follow the directions.
Everything about this frame is pure excellence. The trigger is amazing. The board and programming is insanely easy to operate. The qev makes it fly faster than imaginable.
In my opinion, the qev does much more than helping w/ cyclic rates. The sound signature is changed. The kick is reduced.
I love this frame..........
