whenever we thinks about a thrust vectoring mechanism, we thinks about heavy magnesium or brass gears holding all in a water sealed pod..and makes it heavier and battery eater..but here you can see how simple is to make a perfect thrust vector mechanism, with handy things..all expalined things are only a key, and you can use any apropriate materials,with you..size..materials, motors all up to you..and one request..never consider these efforts, as because of my disability to buy anything, but if we buy all needed things then what will be our contribution in to our modeling..? so, we must research our own..again..again..at last sucsess..
here, according to my idea, the intented tug must be powerful..so, a fast reving prop with less angle is not a good mach..so, i have to make an entire unit for the purpose..including the prop..so, start..
all we know, a vertical thrust vector mechanism must contains two tubes, one is a holder tube, (most outer one) while the second inner tube is for altering the angle of steering, while a thirdth shaft, not tube is intented for driving the prop..briefly, steering and driving process happens simultaneously..
so wee need two tubes, that one holds the second one within..so, i turned to a ball point pen, and a piece of brass rod..to my experience a ball point pen body shell is very nice for most of the RC boat application..you can use anything apropriate to you, like brass tubes..carbon fibre..anything..
