Electronic parts for a custom 3D printed JNR C62 using radio control

[T.S.R_FilmsYT]

Hi, I am in the process of beginning a college project and I am using a 3D printed JNR C62 in 1:22.5 scale (G scale for Japanese 3'6" gauge) but I am not sure on what parts I need to get to be able to make it function. I am wanting to keep the costs to between £100 to £120 so I would sincerely appreciate any and all advice on what parts are needed and where I can find them for good prices. I'm mainly looking for high quality and reliable parts that can withstand, not only filming of the video but general use as well. I would like any and all help that can be offered to achieve this of becoming reality.

You could easily burst your budget with wheels and motor. Look at Walsall Engineering for wheels, JH make superbly reliable gearbox drive motors. Another option may be to bash a RTR loco, but here I think you may run into problems with cost and a correct sort of loco. But the LGB 2-8-2 ref 21832 White Pass loco chassis may be suitable again at a cost probably £500 or so now.

Welcome to the forum. As Dunnyrail states, motors, gearboxes and suitable wheels are the wallet busters. If your loco has been 3D printed, there may be some recommendations in the instructions, or program.
Out of interest what is the film you are making about?

Yep - the bad news is that scratchbuilding is more expensive than one thinks.

I built a home-made chassis for a 2-6-2 with bogie tender and the wheels alone cost £120 over ten years ago. Motor/gearbox (with a Buhler motor at bargain basement discount price) £85.

That said, the loco is still running

I think I should clarify that I'm having the entire model be 3D printed (including the wheels and chassis); similarly to how lego MOCs are done just in a far larger scale.

Thanks for the welcome. The project is based on the Osamu Tezuka's OVA 'Yamataro Kaeru' (Yamataro Comes back) released in 1986 but with some changes to the story.

If motion and wheels are being 3D printed, and similar to the idea of Lego..

Then perhaps look to the Lego motor offerings?
These will already be proven and up to the task.

I did initially have a look at buying lego equipment to run them but I then backed off the idea as I realised that finding genuine lego power functions stuff for a good price is near to impossible.

How about the range of Tamiya motor / gearboxes? There's quite a few offerings, and some that will have enough power for a loco and a couple of wagons or more

I've had a lot of success using cheap gearbox motors from AliExpress driving the axles through brass bevel gears.

I've been playing around with GA25-370 gear motors and bevel gears from AliExpress



The results seem to be quite successful

You could play around with those as your power source or see if there are some larger, more powerful gearbox motors on AliExpress if you want more pulling power.
