I have already post some items on this, so will just link to those post, and also provide updates, so these are the previous posts:

Initial run of 12 hp rail motor:

After a number of false starts on what I wanted, my main item will be a motorised Timpdon Santa Sleigh, run on a a IP Engineering budget 4 wheel drive low voltage chassis. The sleigh was constructed in accordance with the instructions, however the sleigh runners were fixed when it was all be complete due to them being fragile. The photo show the completed sleigh, with the power switch and charging socket in place:

Two (rectangular) holes in the base - when the IP Eng chassis was fitted (hole for the motor), it was found to be very noisy in forward, and no amount of fettling would sort it out so the motor was turned around.

The electronic connections in place.

The IP Engineering chassis is a very basic kit, this shows me leads fitted in place:

The instructions suggest the motor is held in place with silicon adhesive, I didn't like the idea, so two pieces of 3mm foam board was used to "trap" the motor, this also raised the chassis height to match the Timpdon original chassis height.

However to ensure the motor and gears were not under pressure a backing piece 1mm thick was added to the motor support.

Blending the Sleigh to the chassis, using the chassis own mounting holes, and centralised on the sleigh, charging point and switch clearly visible:

I like to make my electronics modular so they can be disconnected for maintenance

The heart of the electronics in a Deltang Rx41d-22 and ADD2, courtesy of RC Trains (bought for a different project, but didn't work for it), and a 1S LiPo battery. As you see these items easily disconnect and the male and felmale connections help prevent incorrect assembly.

In place, I will use velcro to secure.

A quick update on Santa's Sleigh. The metal wheels (supplied by IP Engineering) were noisy on the plastic track, and tended to bind slightly on the curves, the B2B was 28.2 mm which is within specification, but I was unable to narrow this due to the chassis, also part of the issue was the thickness of the flanges. The plastic wheels with the Sleigh, were also designed for 3mm axles, but had a boss on the inner face, which was easily removed, and when fitted the B2B was was 27.4 mm, and now run quieter, with minimal binding though of course the inner wheel and outer wheel, due to the curve, slip.

The electronics are now Velcroed in place, with a false base, and now adorned with prezzies, so I think this is now finished and ready to go:

Lovely sleigh.
A team of reindeer in harness , swinging around those curves would be short lived and hazardous.
Perhaps a single humble donkey….lol.
Needs coach lanterns, me thinks.
 
Aren't the reindeer meant to pull the sleigh ? :think::think:
Only on snow, and this is s'now railway so electric motor ;)
