I’m building a Skymaster 1/7.75 scale A-10 that will be EDF powered. Since there are so many EDF options Skymaster leaves the inlet ducting and thrust tube to the modeler. Thrust tubes for A-10s are a challenge as they require an upward tilt to the end section of the duct so a simple rolled Mylar tube won’t cut it. Best I've come up with is to have someone cut the shapes I need out of foam, that I can then glass and make a plug. Since I only need two of each part I won't need to make a mold just wrap fiberglass around the plug and split the part to get it off the plug. I’ve sent a drawing that shows the 3 simple shapes (2 cones and a cylinder) I need to several foam cutters and got no response. The other way I thought about making the plugs was to get someone to 3D print them, only I don't know anyone with that kind of equipment. Is there anyone out there that would be willing to look at the pieces and see if they can help with the parts?
