Hey if you want to go with the Digi's then go for it,but the 225's will be fine. Chris will even tell you
I got mine to balance with one in the rear .Im also using a lightweight Turbo Header that helps.But have to make a battery tray behind the rudder servo.
Balances with a 2cell 1200mah Etec lipo and Castle 10amp regulator about 3oz overall.Can go to a smaller pack if I wanted to also to rid of a couple grams.
Im using the .82 also [8D] with a JR ds 285 for throttle mounted up front on the box.
