Default H2O, how many volts?

i have a megatech h20(i got it on ebay used with batt and charger for $25 shipped!!)
the battery is a 7.2v, but can the stock electronics take more?

i had a zig zag last summer, but it was not possible to improve it much. the electronics was a board, and a gay motor moved the rudder, not a servo.

the h20 has a seperate RX and speed control and a real micro servo. so, im thinking i may try to upgrade this one as time goes on.
right now im just wondering if the stock speed control can handle 7 or 8 cells.

Usually these boats are designed for low cost and the electronics are designed with that in mind.

If you're lucky, the components of the speedcontroller have a margin, that will allow you to run one cell more and get some extra speed.
I seriously doubt if the handling will improve aswel, as the boat is rather small.
Most likely the motor will get seriously hot, watercool it, if possible.

Judging by the video's, a few sprayrails wouldn't hurt.

In some of the video's, the water climbs up to the deck, enlarging the wetted surace of the hull, causing drag and, if there's enough power in the boat, will cause it to stick the nose in the water going into a sharp turn.

A sprayrail is positioned on the edge between the bottom and the side of the hull, deflecting the water sideways.

The hull in the picture has them built in, but you can add them afterwards.
