I have had two Roo's now and both have been set up with elevon control only i.e. fixed inner/outer control surfaces together and then running two Hitec 5645 or JR 8411's per wing 'Y' connected then one panel to ail and the other to elv on Rx, works great and control in both roll and pitch is more effective. I wonder how much this wing set up style may assist with lower Roo landing speed handling?? as I do not need to use the speed brake either at all I find as super slow landings are the norm I have found.
