yes. I use the synergy 91 3D as a pattern plane. I have the battery just behind the fire wall with the tank on cg running a ys110.
You will love this plane, it flies very light and manageble. I have reduced all the throws on the surfaces to fly pattern smoothly. The cg is at the forward range to give stability. If you want 3D just move the battery back behind the wing and increase all throws.
I just use my synergy for pattern and it performs all the manovers very well. Good choice!!
