I'd like to wake up my SSE a bit for 3D... Currently I have my CG about 3/4" back from the main spar. The main spar (A) being the starting point CG recommended in the instructions that came with the kit.



How far do folks move their CG back beyond this 3 1/2" starting point marked as A?

I've moved my battery pack back in the radio area to just in front of the antenna tube hole and this yielded 3/4" for B. Think I've read that some folks go back so far as 2" for B to be their CG by placing the battery pack back under the turtle deck.

With all of mine, moving the rudder servo to the tail was enough to get an aft CG for some good 3D flying. I also had to enlarge the rudder for better knife edge performance.
