Default Live Nitro Diesel Anyone?

Hi all,
Doing a small feasibility study to see if their is any interest in some small production runs of live diesels. As most of you already may know, these would run on R/C car engines with a mix a real diesel to power a generator to run the drivetrain much like a real engine. I want to make sure there is a demand for them before I go to the effort to secure the licensing etc...


I have most of the rough prototypes completed, and thought others may be interested in them too.


They would be available in a few versions:


GE ES44AC
GE AC-4400/Dash 9
Ge's have both Hi-Ad and curve bogie truck options.


SD70ACE/90 mix


-All would use 2.4G control with telemetry feed and FPV available options.
-LED lighting options
-cooling fan options
-coupler options
-kit options
-base frames are wood, with 3Dprinted parts with epoxy top coatings.


Live diesel and electric battery only options - so you can run them inside and outside on live steam layouts and garden layouts.


They don't have the highest detail level to save on prices; however, their are a few fine scale part dealers already out their you can choose from.


Thank you all for your time.

I think that you would need to give a few more details to gauge interest.
The main ones would I think be price, and scale.
Those that I have seen from past available models, were noisey and smelly and troublesome and not something that interests me, although initially I thought them to be neat.
Good luck with the project.

The scale should be around the standard 1/32 or 1/29 range.
Prices depend on the options you choose. Probably around $380 starting for customer assembled base kits to $2500 range with loaded options.


Exhaust options have two available-one is around 62db to 72db. They can be run fairly clean/low to no smoke, or higher mix with smoke. Smell is mainly nitro or diesel, depending on how you mix it that day. Such as, 50/50 90/10 etc...., so it matches the prototypes fairly well.


If someone is worried about the noise level or smoke level, they could get the electric battery only or fuel/electric switchable versions too.


I hope this helps your questions.
Thank you

To maximize your market only make them in 1:32 scale.
1:29 fans will not care about scale but 1:32nd fans will not buy them unless they are scale.

I would be more interested in earlier diesel prototypes like a GP7, GP9, or SD9, something that wouldn't look out of place pulling steam-era rolling stock, and definitely 1:32.

I would say earlier as well. Even a boxcab in say 1:29 easily to integrate into steam era and even 1:22 or 1:20 narrow guage

Jerry from Hyde Out Mountain produced a kit a few years ago, could put in any shell.
. Here it is in an Aristo RS 2 with R/C.

Wada Locomotive Works also produced a few. I have seen several (Wada and Hyde-Out) over the years, and yes, they are/were noisy and not very prototypical in sound.

I would think there are a few ex-airplane guys used to diesels, and that you could sell a few (6?) I concur with the 1/32nd, though it may be possible to drop a 1/29th body on a 1/32nd frame if you wanted to?

Yes, I've seen many of the others over the years, but they all used older technology, can be hard to find, and can be very expensive. Most of all I wanted to do something that people have not had currently very available.


These were more to go with modern live steam excursion trains and for electric modelers who can't find any other manufactures making these anymore or ever in the past with the electric versions. These use modern (ESC) for speed control, so the power is smooth and consistent with very low engine RPMs. Their is no need for those large lead acid batteries anymore too. Once the engine is started, you could actually not need any battery at all to run these. And for the pull-start option, you don't even need the auto-start battery.


I've made a SW1500 already too, but the smaller engines can be challenging to fit all the new features that we have available now. One of my favorite diesels is still the GP-35 or GE-U25B, so those would be a higher probability of me spending the hundreds of design and assembly hours it takes to make them. But I will definitely consider the others you all have noted.


Thank you all for your time

Seamboil, the large lead acid battery is only used on starting, the plug is then powered by 2AA batteries until the heat and compression take over.
. Even though I did build the Hyde Out Mountain, and did enjoy the project I would be interested in what you are proposing. Would it also be offered as a kit with just the engine, generator and accompany electronics that I could adapt to any existing sparkie I presently have??? Thank You LiG
