Any chance of details on the power set up?

I have the 46inch fibre glass hull version I use a brush motor direct drive onto an x45 prop powered by a 12volt 7ah jelly cell battery with 15amp series fuse using relay switch for fwd rev, runs really fast planing until battery power falls but cant get any where near the 40 mins jelly_baby gets using lipo cells my visits to the lakes when I lived in Bedford consisted of getting the boat to the lake then 6 12v 7ah charged batteries being carried from the car.

HI DeltaTango01 using the same motor and Prop (45mm 3 Blade Brass) with a direct drive I found that the amp draw was excessive and this made the run time very short. but by fitting a 3:1 reduction gearbox I retained the speed and dropped the amps used by the motor it was running much more efficiently. Thats why I think the run time Improved. I sail on a sunday morning from about 10.30 to 12.30 on 2 x 11.1 5100mAh lipo's and 2 x 4.8v 3700 mAh NiMh in series (9.6V). Hope that this helps DeltaTango01.
