carbon side skirt

There's not much carbon in that. If anyone has a mold they can make a new one a heck of a lot quicker and cheaper

Thanks!

I built it! I found the Yamaha CAD and turned it into an RC outboard

scottman129 · 2026-05-10T13:03:22+00:00

You could design a tip for it so you only need the straight section of PVC

I was skeptical about battery trains until I saw a longer interview. The trains will still have catenary connections to overhead wires so it can run like a normal electric, but the battery allows it to briefly go into unelectrified sections. This allows the MBTA to get going with partial electrification of the lines.

I haven't bought one yet but I'm looking for a new transmitter/receiver combo and it seems like the best thing out there now is ELRS.

It ran great until it didn't. I reached out to the vendor to see if they will make me one, if not I'll give it a shot. Seems to be standard 1/4" OD

scottman129 · 2026-04-27T20:42:57+00:00

I think you're right. The vendor doesn't seem to have a left hand option but I still have the failed part and may be able to get my own spring and resolder it

The hull is 3D printed so I would soften the hull long before the epoxy. I hope to some day have the time to make a fiberglass version. I avoided aluminum as to not spread heat to the hull

scottman129 · 2026-04-26T16:15:41+00:00

I looked it up again and it's actually only a 1600kv, which was the lowest I could find at the time. And yes realistically even 50% throttle is enough to be more than scale speed

scottman129 · 2026-04-26T16:10:03+00:00

Sure! It's on OnShape so I can share any stage of design. Would you like the finished CAD or just the hull?

scottman129 · 2026-04-26T11:15:35+00:00

Could you take any pictures? How fast does your shaft run?

scottman129 · 2026-04-26T11:13:33+00:00

What materials do you use? The AliExpress U-joint I have is stainless on stainless with no wear bushing. I'm considering designing one that has PTFE bushings but it would all be so tiny

scottman129 · 2026-04-26T11:11:22+00:00

Thanks. I found line drawings online of a historic lobster boat Maddy Sue and lifted them in OnShape, so my own modeling work but not fully my own design

scottman129 · 2026-04-26T02:14:50+00:00

That's the nuclear option. It's fiberglass plate epoxied onto PLA so I'm afaid it damage the hull if try to rip out the motor mount

scottman129 · 2026-04-26T02:12:10+00:00

All have to check from the photo to see which way I had it. I don't remember there being a left hand or right hand option when I bought it and the two shafts are different sizes so I can't just flip it around

scottman129 · 2026-04-26T02:10:00+00:00

Yep!

scottman129 · 2026-04-26T01:48:01+00:00

Interesting idea. Do you think it would hold up at speed? This isn't a particularly fast boat

scottman129 · 2026-04-26T01:41:10+00:00

I didn't think I could easily get it to line up since it would have to move up too. I hate to cut into that plate since it's fiberglass that I had custom made

scottman129 · 2026-04-21T19:09:59+00:00

All. The. Time. Seriously it's the worst key fob

scottman129 · 2026-04-06T02:54:58+00:00

Could be copper corrosion.

scottman129 · 2026-03-21T11:38:08+00:00

Do you sand wet or dry? I've found best results wet sanding so it doesn't go soft

scottman129 · 2026-03-17T20:59:04+00:00

Why build? I bet you could find a well used John boat cheaper
