Fitting a quart into a pint pot.

[Tony Walsham]

I recently acquired one of the tiny Bachmann Davenport locos and fitted RCS battery R/C, batteries and MyLocosound.

The stock Bachmann pcb was removed and a new styrene plate cut to fit using the original internal stanchions and screws to hold it in place.
The ALPHA-3v2 combined RX/ESC sits on the styrene sheet with the LT-SW4 extra sound triggers pcb.
I mounted the new MyLocosound diesel sound under the hood cover for easy access.
The wiring is not as neat as I would normally do.

The 4 x AA size 850 mah battery pack fits just under the styrene sheet.

The ON-OFF switch was mounted under the front of the loco.

All buttoned up with the new RCS TX-21+ handpiece with Inertia control.

Loco is very smooth and steady on the track but on rollers it wobbles terribly. Go figure.

Tony,
Nice Shoe Horn Job, I have been pondering the Latest My Loco Sound Cards. Have one of the Older Ones and to be honest am not too impressed with the Electronically Sampled Sound. BUT I gather the new ones are so much better.

Are they sampled from a Real Diesel.

Any chance of a Vid to hear the beast please?

Hello John.
The new diesel sound is way better than the old one but not yet quite as good as the steam version.
Sorry, no chance of a video, I have no idea how to do them. I do have a camera that supposedly can take videos but I am not very clever with that sort of modern technology.

I have just been given (Christmas pressie from SWMBO) the Banta modelworks kit of the crew cab box car that its the Davenport chassis.

I take my hat of to you, Tony, for the shoehorn job

Clearly there will be bucket loads of space in comparison to the Davenport body shape, but I have been taxing my brain for ways of making the switches and charging sockets less visible.

I am intending to experiment with a plunger on/off switch by connecting it to the exhaust pipe. Press for on, press again for off.

I haven't received the chassis yet from Essel, but I'm wondering whether I can locate the charging socket in the footplate under the body overhangs ??

Happy battering O0 O0 O0 O0 O0

Neat job, Tony. Is the wobble on the rollers something to do with the fly cranks perchance?

Rollers aren't the same profile as track ?? :-\ :-\

Hi RC.
I too struggled with locating the charge jack. Mainly because the body of the jack I usually install would have had a potential of some sort. Depending on how it was wired up. I ended up using a flying lead under the hood. The charger I use has a variety of connectors available so the regular servo type connectors works just fine.
The actual placement of the parts was relatively easy thanks to the minute size of the new Deltang combined RX/ESC. It is slightly larger than the first version but still very small.
More importantly it has three open collector/open drain outputs for lights and/or sound triggers. I can plug in a small 4 x transistor pcb for a total of 5 x sound triggers.

Thanks Rik.
Because it runs just fine on track, someone has suggested it is the rollers themselves causing the wobble. Not quite square sitting on the rails. Or it could just be because it came from AristoCraft. ;-)

Ah - the decision regarding the charging jack has been made for me - the Essel chassis comes with two holes of the correct diameter in the side frames - one for a charging jack, the other for a toggle on/off switch.

I'll use the one for the charging jack, but I'll persevere with the exhaust pipe push /push switch, because I'm a bit of a contrary wotsit at times 8) 8) 8)
