what is a bigger prop i can use
i have a 70cm rc boat that has 2 380 size motors and is surface drive and i want to know what bigger props i can put on it because the boat speed isnt very fast and the motors dont seem to struggle at all with whats on it now (35mm), and the prop shafts are threaded and they are tiny and also use screw on drive dogs
heres a link to a site that sells the boat, it was $60au on ebay

RE: what is a bigger prop i can use
You could always just jump it up 3 to 4 mm and see how the motor temps go. Even the smallest upgrade could cause you to burn out the stock electronics. They build these boats as cheap as possible and that does not leave much room for error. When you say the motors dont seem to struggle, have you actually checked the temp after a full run?

RE: what is a bigger prop i can use
after a full run the engines are a bit hot but i can put my hands on them for a while
and soon as i press go on it it is on plane and the motors rev high straight away easy, and one of the motors go faster than the other so it always tries th turn left wich is really anoying
if the prop is too big will it fry the motors or the radio or both
