RE: reciever question
As a relative newbie myself, I remember the first plane I had with dual alieron servos (a Seagull Skywalker). I decided I would use a seperate channel for each servo, mainly because I didn't buy a "Y" harness and was over my budget already. It did take a little bit of fiddling to get set up and working, mainly working with the radio (a 9C). But once I had it figured out, (and it really wasn't all that hard, in retrospect) I think I was better off for it. Always pays to learn something, and a dual alieron setup is one of the easiest and least intimidating to figure out. Plus, it simplifies servo installation.
Now, if I can figure out how to get flaps and not airbrakes on the Twist I'll feel like I accomplished something...
Oh and I almost forgot.... I suggest the Ernst connector securing devices, you'll need a couple pieces of shrink wrap or tie wraps to finish the install, but once connected and installed, they're nearly fool proof and very light.
