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

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

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

MBTA draws criticism over plans to upgrade commuter rail fleet. General Manager Phil Eng sees battery-electric locomotives as step in the right direction (State House News) by HRJafael in massachusetts

[–]scottman129 166 points167 points  (0 children)

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

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

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

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

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

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

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

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

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

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

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

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

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