I recently purchased a Tower Hobbies 2-meter Vista EP. The manual specifies using a 7 cell, 8.4v, 2000mAh, NiMh battery, I have an E-flite, 3S, 11.1V, 3000mAh battery onhand, can I use this E-flite Lipo battery for this aircraft? I called Tower and they said I needed a regulator but couldn't tell which type to use! Any one out there using a Lipo for this aircraft without causing any ESC and motor problems? I would appreciate any help and advice concerning this battery conundrum.
