I need a source for a good set of screws (propellers) for the Revell Lionfish/Growler model. I have neither the tools nor the knowledge (or the eye sight, for that matter) to build them myself. Does anyone know a source for them. ConUS if possible. But if the only place to get them is outside of the country, that's what I'll do. I just hate all the paperwork and government aggravation.
