IP Engineering Albert

Post by ge_rik » Sat May 05, 2018 10:06 am

I've been at it again - this time an IP Engineering Albert.

.
I found the build to be a bit fiddlier than the HGLW build as some of the parts needed to be aligned by eye. However, probably a day's build to get her to this stage. She's powered by two 14500 (AA sized) li-ion batteries which just (only just!) squeeze in under the chassis. They are wired in parallel (to get twice the running time). Deltang receivers are happy to run off one 3.7v li-ion battery and include automated Low Voltage detection to cut off the supply when li-ion battery packs fall below a safe level. I've set her to 32mm gauge as she will shuttle back and forth on the copper mine feeder line (using the built-in shuttle feature on the Rx65).

.
She's controlled by a Deltang Rx65a receiver. The Rx65a has been superceded by the Rx65b, which is slightly larger and more powerful. However, I had this Rx65a left over from a previous conversion and so waste-not-want-not! The receiver is just visible above the motor in this shot.

.
I'm going to add Delrin sprockets and chain drive to improve her pulling power but she will happily pull three Binnie skips (providedI don't try going round any curves or up any hills).

I'll blog the build when I've done a paint-job on her. I focused a lot more on the wiring-up this time as I know that's an aspect which some people feel apprehensive about.

Nice little loco, it could do with a bit of weight I guess..
And it needs a scale fire extinguisher, you are a brave man putting "Trust Fire" batteries in a wooden locomotive.. :lol: :lol:

I do feel I could switch to li-lion batteries as I have read enough about your work Rik to wire them correctly but it's the cost of buying a suitable charger that puts me off (the charger I currently use cost me under £20 and charges all my locos + trickle charge).

Hi Tom
You can get a (cloned) iMax B6 charger for just over £20 - eg https://www.ebay.co.uk/itm/152999311666 - They charge just about anything which can be charged and you can set the charge rate from 0.1A to whatever you fancy - even includes a heat sensor input for the mad car fast charge crowd. You'll see some scare stories about cloned B6 chargers. I suppose it's the luck of the draw, but I've been using a B6 clone for over 5 years now and ...... so far, so good.

Tom, I agree with Rk, I've been using an imax b6 for several years with no probs. It is/was a bit of a 'mare to get to grips with the instructons but Rik did one of his mega-helpful blog guides which makes it all pretty plain sailing.

Hi Daan
I did put a bit of lead in her, but the problem is the 2wd chasis. I know from past experience what a difference adding 4wd can make. Before adding 4wd, my Simplex could just manage 4 skips on the flat but that was her limit - and she certainly couldn't tow them up a gradient! As you can see, adding 4wd made a world of difference - no extra weight was added, just used the weight of the whitemetal body before and after adding the chain drive.

Thanks Philip
Yes, the instruction manual assumes a fair bit of prior knowledge and is also written in Chinglish, which makes it even more indecipherable. I'm sure you'll have no problem figuring it out, though, Tom. It sort of makes sense once you get over the initial learning curve.

You don't really need a fancy charger if you are just going to be charging a couple of cells. The very cheap fixed rate balance chargers will do the job.

May be a dumb remark: 3.7 volt Li-ion is about a mobile phone battery. Would a charger for those be working?

Nice video Rik! It really is a strong puller with 4x4.. Great layout with the little bridge across the small river. :thumbright:

In theory it could, Daan. But mobile phones include circuitry to monitor the charging process and the charger just provides the power. An 'intelligent' charger includes the circuitry. It is possible to buy a circuit board to manage charging but it would have to be wired into the loco (or added to the phone charger).

Thanks guys, I forgot about Rik's blog about the charger so I think I will take the plunge next time one of my NiMH packs dies as I would like more space in my Cricket to fit a smoke generator.

Video of her test run. Not very exciting, but gives you an idea of her in action.

Another superb build Rik.

While I still procrastinate over the HGLW kit you built and made me decide would be my next project you've now made me reconsider.

Based on your experiences, which would you say is the more powerful?

Thanks,

Ian

It makes a nice little 2-stroke engine noise.

Not sure, as yet, Ian. At the moment, the HGLW loco is by far the most powerful, but that's because it has 4wd as standard. After I've installed 4wd on the IP Engineering loco I'll be able to make a better comparison.
