hi. i built this little micro airboat for running around my pool (full of leaves and stuff lol). made of foam and balsa. it uses micro t electronics and a homemade prop (aluminum sheeting bent to shape.) it goes ok, but not much speed. the first design had a narrow prop. i kept cutting it down and it seemed to blow more air when it was smaller. then i make this prop which has big fat blades. it goes alot better. despite the big prop, the motor seems to get pretty good rpms. im thinking i might make a bigger prop? what do you guys recommend for the prop shape and size?
hers some pix of the boat.
