hawk3ye, I'm with fliprob on the rudder /throttle mixing, that's a lot to get into, for, from your questions sounds like a beginner. If need be PM me I can take some photos of mine for you so you can see how it's set up with the Y harness's and such. Mines the bright red "YIPPEE" one in the forums.
A twin is double the trouble and twice the fun.
Also something else, before buying the brushless setups from EMI, you should check out some other sources. The motor/esc combos in mine were $45.80 for 2 brushless motors and esc's.
Oh and lastly, there is no such thing as a dumb question. Dumb is doing something and then having to ask why it didn't work.
