Hi all,
I have been working on a electric rigger design for the last month or two and finally ready to move it forward to the build phase.
I have previously built some custom shaped bodies for RC cars from carbon fiber. One was features on Raz Shifrin's YouTube channel if you follow cars at all. Link here doing 153 mph.
(Sorry I don't have the time to make you something, but happy to talk about the process or help you do it yourself shoot me a PM)
My part making process has been:
1. Design in Fusion 360
2. 3d Print from PLA
3. sand/body filler/primer to finish to a smooth polished surface.
4. Wax and PVA
5. Create mold with gelcoat and fiberglass
6. Wax and PVA release on mold > Generate final product from fiberglass or carbon fiber.
With the car bodies there was only ever the top and side so I could make the body in 1 mold and didn't require joining another body part.
How is this typically done with boats as you typically will have a top and bottom that need to be fused together to make one solid hull? I assume epoxy plus fiberglass or CF reinforcement on the inside.
What is your experience on what works best? I think the main hull wouldn't be too hard but the sponsons are very small and wouldn't have space inside to apply reinforcement.
I was considering making the sponsons via a skinning method instead by coating over the 3d printed shape.
Current design less the ground effect wings in the rear:
Thanks in advance for any guidance!
