I have recently bought a 2nd hand torpedo boat.This i my 1st rc boat.It has a bilge pump built in but doent seem to work.

Also i dont seem to be getting the full power out of the boat,im running it on a 12v 7amphour battery but it still seems slow.

Would it make a difference if ichange the prop to a left handed one?The speed controller i have put in is a 40amp one,would it make a differenc if i was to solder these connections to the motor as there on lugs at the moment.Would it be possible to double up with another battery,also when in the water it struggles to stay in a straight line.Would getting a bigger prop help its currently got a 70mm brass 3blade prop on it.

Cheers ashley thanks for the advice and a quick response.

The boat is just over a metre long,ive looked at the motor but theres nothing on it that states the size,would it help if i put some pictures up of it?

What size prop would you recomend going for then,and could that be the why the water isnt going into the bilge pump which is located by the rudder?Cheersmat if ya culd help us out some more would be gratefull.
