hi all
forgive me if this request is not strictly to do with pro pilots.
im currently building a scale b737 rc jet of around 2 metre wingspan most of the work i have some sort of ideaon how to go about it, but does anyone know of any cheap or possibly free cad program of some sort i can use to create a working model of the flap mechanism.
typically i would pick the 737 with triple slotted flaps!!
i dont really want to carve out a load of hobby metal only to find that it doesnt work!
here is the link of what im attempting to create
any help would be great
thanks
Patent US6598834 i know its ambitious!!
