Street price of the 8611 is going to be $114.99. I have heard that they will be released mid Nov. some time. I also expect the price of the 8411 to drop after the release of the 8611. I would guess if you use 2 matchboxes for the wings, you would have to power each one with a battery. The instructions say if using more than two servos on each one, they need a power source. I have 4 on the wings and 1 on the rudder. It is a few more bucks to spend, but the set up was a breeze.
I am also taking pre orders for the 8611 servos. If anybody would like to back order them with me, please private message me.
Thanks
Brian
