This boat is still under constrution (Ive still to finish "Shell Pioneer") so a lot of the above is only guess work however a bench test at full throttle, with sound generator, amplifier and smoke generator operational it drawing less than 3A. The majority of this was the smoke generator with the drives only drawing 0.25A (under no load) so if these figures do not increase too much once in the water i should get a much longer running time from my 2 lipo packs (Motor: 2xMFA970D161LN) (ESC: action elelectronis dual 10A ESC/mixer) (5/10)
