I set my dad's cub up the same way, evan set up his giles 202..
everything was matched with my programmer (hitec) and I used simple y's everywhere.. the only thing different was I used lipo's instead of nimhs
worked great for me and I have never seen a glitch in the system yet
and its a cub so you wont be working the servo's to the max unless you fly it like hempel does
and yes a powerbox or smart would be nice but not needed they make set-up a breeze.. I run the powerbox champion and setup is super quick
race
