I love 4QD stuff. The new one has an RC input. I missed that by a year :o) me wanty.
Nice vid :o) my four wheel shunter is 1:8 scale and I have to say, it is a tad heavy. My wheels move in to make it 5”, which gives me more tracks to run on in the U.K.
Matt I'm enjoying your conversion process. I'm doing the same thing and getting ideas. Looking forward to your 3rd part.
I am glad you are finding it useful! I am way behind on getting videos out. Hopefully part 3 will be here soon.
Totally awesome Matt. That was fascinating to watch. You are a craftsman. 👍😊❤️ forget love go for lust 🤣 sweet whistle on steam loco
Thank you for checking it out! The VW van is a video all on its own. The other good sticker on it is "O to 60 in 5 minutes.
Amazing work. Nice train ride. Thanks for sharing. Dave
Good, was wondering about heat build up. Tnx
Wow! Nice and in depth! Yeah, get a tripod and keep sharing!
Thank you, it's always a choice between buy camera equipment or buy more train parts..... And you can see for yourself how that decision has played out. 🤣
Wow Matt, you always have all the info for us. That's looking great. You always do great work. The bonus footage was cool, where was that at. And I think you need to tell us about that live machine in the background 🤣 the VW Van...
Thanks Pappy! If I start telling a bunch of lies, call me out 🤣 The bonus footage was taken at Great Smokey Mountains RR, I was chatting technical stuff with staff (while staying out of the way) and before long they said "if you want in the cab, just act like your staff". A memory I will take with me to the grave. I never expected to get a cab ride. I will do a video on the VW camper some day. Maybe when it's not 7⁰F outside.
@@mattkinnard6899 lol you have way more knowledge about a great many things. I wouldn't know the difference. So, so cool you got a cab ride, thats fantastic. But seeing how your an age of steam tour guide. Dosnt surprise me one bit. Love your videos...
Thank you! Your words make it worth the effort!
@@mattkinnard6899 Thanks for filling-in the cab ride info at the end. That engine was holding the rails very well under that load. Your cab ride story is very similar to my first, and as yet, only cab ride story, but my steed was an EMD E8. 🤠👍
From where did you acquire these two motors?
See link in video description. I purchased from electric scooter parts.com, but they can be found from many different websites.
Awesome build Matt... I like what you did with the electric motors (dual motor). Did you purchase the chassis, or did you build from scratch? I hope to order a three axle (0-6-0) side rod "Davenport" chassis from RMI at some point in the next year or so. They have a two (electric motor) option, which I think would be worth it.
I'd also like to build my own chassis of the same configuration, but I need to purchase larger machine tools to do so... Cheaper and quicker to just buy a customized chassis, then build my own body for it.
I would rather be over motored than not have enough. At the very least, when working under sustained loads motors get hot, and torque decreases with increased temperature. More motors for a constant tractive effort means your using a smaller percentage of the motors total capacity, extending the life and reducing heat losses. I operate at Mill Creek Central, very little flat track there. I can pull 11 car trains up 3.5%+ grades or 3 ('murican sized) adults and 6 cars to date. The frame is all scratch built. Places like send cut send can laser cut metal frame pieces, bearing boxes and more. There tolerances are tight. By the time you polish the cut surfaces with a little sand paper you will have just enough slop were the suspension won't bind up. Tolerances being to tight tend to cause more problems than tolerances being too loose. I do not have machine tools. Only basic hand tools, welder, drill press, and a mind that's good with problem solving and coming up with creative solutions.
@@mattkinnard6899 Thanks for the input Matt... I follow Mill Creek on YT. I could probably could do the same as you have without machine tools, but it'd certainly be easier with! I have access to industrial laser cutters (I work for a mfg) and can laser cut up to 1.25" thick steel. Have a partial design for the frame/suspension for a Davenport 0-6-0 diesel mechanical. I just need to finish up the frame design and start laser cutting parts. Hope to get that done before I retire in about a year and a half. But short term, I've been corresponding with RMI about a customized chassis based on their 3 axle/6 wheel Davenport D&RGW #50. They'll build it, just have to come up with the $$$. Hope to start experimenting with track and turnouts (switches) sometime in the next year or so... Hope to model 24" gauge on 7.25" gauge (but use 3.75" = 1' scale).
@@WHJeffB sounds like you have a good plan! Best of luck with it!
@@mattkinnard6899 We'll see... What you've done is great inspiration and gives me hope that I can pull my own locomotive chassis off at some point in the future.
Good day! Would you mind sharing what kind of motors you are using on this build and where you might get them?
24V DC, 450W, 420 RPM, part number MOT-24450G they are all over the internet. Ebay, Amazon, monster scooter parts, I believe I got mine from electric scooter parts.
Geared at 5 mph top speed my locomotive is a great puller for a 2 axle loco. I have pulled 11 car trains up 3%+ grades. And have the torque to accelerate and great regenerative brakes.
Heat load? Will a blower for cooling, be needed?
I have not needed one since the motors are oversized
do you think that your wheel base is to close?
Good question. The wheel base has not been an issue and in the two years I have been running this frame (many many miles) I have only had it derail twice, and one of those times was from a stone wedged in a switch frog. The wheel base is very close to the prototype. The locomotive rides down the track well, and the suspension does not bounce around excessively.
well, i am in the process of building my own battery powered locomotive.
but man, you lost me BIG time, controller switching power off and on capacitors and R.F. noise and whatever else on a motor.... blank stare on my face now. i'll watch this again a couple times, but i reckon it's gonna be the deer caught in the headlights.......
I recommend going to the 4QD website and navigate to the FAQs drop down menu, and select technical. Here you will find a bunch of technical documents and videos to help you out. Namely, check out the section on motor noise suppression and watch the video there. If you skip motor noise suppression, it can mess with track signaling circuits, and WILL shorten the life of your motors and controllers. What I can say is that my ~300 lbs locomotive can pull 2,000 lbs up a 3% grade, and the motor controller does not get hot, thanks to low gearing. The regenerative braking works great, and battery life is longer than what I can stand to operate in a day, 6+ hours
