I too picked up the Dachs kit back in the 70's. It's the wooden hull version. The kit suggested Marx motors, which I purchased about the same time as the kit.

I had the kit largely put together (I'm very slow at building!!) when I was searching the Internet and came across your Wiesel modifications and how to change from the 3 to 4 shaft. That was about 10-15 years ago. Can't remember exactly?
At the time, I struggled with whether to go ahead with the changes or leave it as is. I had just finishing painting the hull. As you can see I haven't made the change(s), but occasionally revisit the idea. Regardless, I definitely want to upgrade the motors!

Hi Garth.

It was a great day and the weather was just perfect! Good seeing your boat. It's a beauty! 👍 Here are another couple of pictures for you.

This is my first entry on this site, so if I inadvertently commit a faux pas, please excuse my ignorance! Please let me know and I will try and correct for any future entries.

I'm currently trying to figure out how to wire up the LEDs for a Billing Mercantic that is many years past due completion. However this pandemic has given me more than enough time to try and get it completed.
My question is about the wiring and resistors needed for the LEDs. Specifically what voltage to use for the calculations needed for the resistor(s). From what I've read the idea of using the one resistor per LED makes sense for my application.
I plan to use a couple of 3S LiPo packs with an ACTion P103 parallel board to supply the power.
Since the voltage drops as the packs lose charge, what value do we use for voltage? I'm thinking we use the value when the pack(s) are fully charged since we risk 'blowing' the LED with anything less. However the voltage drops from about 12.6V to 9.5V when discharged, give or take. Will the lights still be working, or am I worrying about something that isn't an issue?

Thanks in advance for any light that can be provided!
P.S. I couldn't resist adding the pun. 😆
