Motor Collection - Old School Horsepower

[dinglem]

Whilst on the topic of older motors, nobody has really mentioned modified Mabuchi 'silver can' motors.... I have an MG modified Mabuchi which is discussed here:-

https://www.rc10talk.com/viewtopic.php?f=78&t=44804&p=508571&hilit=igarashi+mg#p508571

Just thought it might be of interest. Similar to the Igarashi's, it has been opened, rewound and ballraced.

While we're on the topic of Mabuchi and Igarashi motors I would like to share mine.
On the top left is a Mabuchi RS540SD. Next to it is an Associated stock Igarashi. Bottom left is an Igarashi sold by RCH which is modified with bearings, a flat machined on the shaft and advanced timing. The turns and winds are unknown. It's intended use is for off road buggies. The yellow tape holding the endbell on looks to be the same as the tape that Mike Reedy used on his own modified Igarashi motors. Lastly is a Bolink Team Checkpoint Stage V which is a full blown modified with slot car brushes. The turns are unknown but it is a single wind. The armature has no markings on it but there is a number 5 on the plate that holds the brushes and a number 5 inside the endbell.

1300GT - those are super nice. Thanks for posting. I really like that Checkpoint.

I have a couple of Reedy Igarashi modifieds... which I believe to be pretty special, although i have only opened one of them up for a nose so far. These are ex-Walt Bailey Mike Reedy 1981 1/12th US Nationals motors.

The yellow label one has a red dot on the endbell, which i believe signifies the spec. It also has ventilation holes drilled in the can and classic Reedy wraps. It actually looks barely used.

I think there are 3 different sizes for outer diameter at those small size bearings.
Also with or without flange.

Do you need some and which one?

[dinglem]

I have them now mate - thank you though.

Maybe there are not many modified Mabuchi motors out there. Beside the Black Mabuchi, which got a black can, front ball bearing and a more powerful wind.
But actually just something of a machine modified.
Maybe there have been no other Mabuchis which were "officially" modified by a motor builder.
Private modifications not counted.

Well I mentioned my modified Mabuchi before but a lot of postings and threads seems to fade after some time.
A couple of years ago I bought a RC12E which came with a nice MRP Kremer Porsche.
Hidden below the body I found a very interesting motor when arriving at my home.
The Mabuchi can got ball bearings and was cutted similar to the Trinity and MIH motor.
Something I really like
But that car is hidden somewhere in my boxes and I don´t disassemble cars usually.

Maybe if you search through my postings you could find that picture.
I have no idea when exactly I posted this.

I will try to hunt for your post.

I know Mick Goddard (MG) was offering modified Mabuchi 540's as i have the adverts and examples of them myself - although i think apart from being 25T the Buggy Special is a stock motor.

April 1983:-

July 1983:-

This earlier advert from March 1983 also tells you that the case ends were ballraced, so he was definitely offering modified Mabuchi as well as Igarashi versions.

The Magnum O B/Race is what my full modified MG Igarashi corresponds to. I have spent a long time hunting out these examples to complete my early MG collection.

MRP moved all of their motors from Igarashi to Mabuchi motors like the cans MG used....and they produced two, or three mod versions. A list of them can be found in the mid/late 80s catalogs: http://www.mrpboats.com/mrp-archive/mrp-catalogs/#

My first ever RC motor was actually a Mabuchi based MRP 550.

One of the other reasons i like the Mabuchi/Igarashi motors is that although they look a bit meh compared to what we consider to be performance, open endbell Yokomo-esq motors they actually can be tuned to perform well. Back in around 1988 our local RC Model Shop owned by Jimmy Davis actually offered their own standard motor... called the JDM 05R. Having seen them featuring in magazine tech charts in standard class competition, and then having raced again Jimmy's brother Wayne Davis when he visited our local off-road club (it was QUICK!) I decided to buy myself one. it remains one of the few motors from bitd that I cannot find - lost in the loft forever perhaps - but I am always on the lookout for another.

I presume from the name it was an Igarashi, but the dating suggests more Mabuchi. I will find one..... eventually!

Even Jimmy himself doesn't have one..... when I asked all he sent me was the photo of a motor label still stuck on to his wallet! He actually told me he sourced the motors directly from Mike Reedy.

Well that´s no surprise. Jim and Wayne Davis were Associated/Reedy team drivers.

Regarding MRP motors I personally prefere their Igarashi motors over the Mabuchi.
I just like the Igarashi look more than the Mabuchi.

Thanks, but I can´t read the label. To blurry when enlarged.
But it´s nice.

I just found some motors.
Fantom motor with Checkpoint Platinum can

Very early Checkpoint Igarashi can.
Not BoLink Checkpoint. Real Checkpoint.
