I am using a Hitec Electron6, and HS55's from my LHS. That power setup, with the 12x6 was previouly in an E-flite Mini-Funtana. The airframe was very lightly built, and I was using a 1350mA pack. The vertical was obscene. The Stingray, understandably, does not have the same vertical oomph, but tracks rock solid. I may try to find some longer LG struts.
