For the Davenport did you just use what you had on hand? Did you have a plan or just went with what looked appealing to the eye?

It looks really nice! Also like the track.


Yup, just used what I had on hand. The hood's cover is actually from a defunk laptop charger that I split apart. It's width was an exact match to the existing hood but provided about 1/2 inch more height than the stock, curved hood cover which helped with the appearance of upsizing the 1:20.3 base to 1:13.7. I tend to wing it with my ideas which I find more fun than trying to follow detailed plans. If it ain't fun it's not worth doing in my opinion.

Unfortunately the RailBoss ESC has taken to shutting down suddenly if I'm running the loco in forward above 75% throttle. Works fine at full throttle going in reverse. Not happy with this and am working on an alternative solution at this time as I'm in discussions with another SE modeler on another forum who, like myself, only wants simple forward/reverse/variable speed control. The RailBoss allows for directional lighting, momentum, horns, sound and the ability to keep running while the TX is off... things I really don't need or even want that runs up the cost of the product.

The track itself is still maintaining itself to the original alignment in spite of the fact that it was simply layed on the ground and covered with ballast. This works for my locale where frost heaving will never be an issue. I do occassionally use a small whisk broom to move dirt/sand from beside the track into the ballast itself which sort of acts like mortar. Other than when my two medium size dogs go to playfully chasing each other and kicking up ballast here and there, the track is fairly robust and doesn't move.

Latest update:

The RailBoss system developed a snag. Seems that when running at anything above 75-80% throttle going forward would cause the esc to shut down abruptly. I would have to back the throttle down to 0% and allow the esc to reboot before starting forward again. This problem didn't occur when running in reverse.

An exchange of emails with the RailBoss' developer never rectified the problem although I have to give him kudos for attempting to resolve the issue. The last resort being to send the RailBoss to him to be tested for $25.

I figured I'd save the money and put it towards another option... that being the purchase of a ProBoat ESC which has the simple forward/reverse feature I want. I picked one up for $42.



Temporarily stuffed the ESC into the hood of the Davenport...



Dropped in the LiPo...



And shot a video of the test run...

Spent the afternoon finalizing the positions of the ESC and the on/off switch. I used velcro to hold the ESC and the LiPo battery. Time will tell how well it holds up to the job.



Positioned the on/off switch on the left side of the hood.



The only remaining component to position is the receiver seen here riding loosely in the cab.



So far I'm liking this setup. Since I have no interest in having sound or lighting on my engines, this was an easy, inexpensive way to go.
