Hello all.
A friend and I are thinking about experimenting with some designs for racing boats. He's going to design them and produce the formers, I'm going to - literally - slap a bit of GRP over them, and then we quickly compare and contrast how well they perform.
In order to make comparison easiar, I'd like to take as many variables out of the equation as possible - as we'll be playing with fractions of a percentage in imporvements.
What I'd really like to to have a "standard" power train - i.e standard motor, battery, wire legths etc.
However, I also want to standardise it more than this. I'd like to add a circut that contantly supplies the same amount of power to the motor.
For example, the motor is set to recieve 50 watts of power ( suppious number from the top of my head ) and it never supplies any more or any less than this - whether the prop is in the water, out of the water or any other factors are in play.
I *think* that this will need to involve some form of feedback loop. Does anyone know if such a component exists? if not, does anyone know how I would go about designing such a thing?
Thanks muchly
Steve
