Got to do a few runs this weekend with my John H-built 36D motors.

Red car has a real hot arm and neo magnets it has run a .807 but I had trouble getting it to hook up and only did a best of .821 @ 63 MPH but on another run I hit 72 MPH.

Blue car the Dragnoda P (Shinoda P body) has a Champion 707 in it with a hot arm; it ran a. 993 @ 69 MPH.

All these runs were done on 16v down a 55 ft scale quarter mile.

Holy cow! 
 
I always kind of wondered why there weren't more hot cans in the drag cars of the '60s. Maybe because of the high voltage... I read the article by Sandy Gross about he modified a Monogram kit with a 16D and would have cleaned up his class at a Car Model or MINRA drag meet, but was eliminated on a technicality - they still featured his car in an article because it was so impressive. 
 
I've found a few period dragsters with can motors, but nothing very fancy. 
 
When we ran some drags in Bordeaux over a dozen years ago, also at 16v, the cans were definitely faster – but we didn't have any sophisticated laminated motors either.

Don,
 
I question that a vintage Mabuchi comm could survive 36v.

[don.siegel]

Like I said, the high voltage, Mike... but there were already tougher commutators by 1965 or '66, and I'm talking about heavily reworked motors of course, even a Champion 703 – although whether the whole thing would have stood up to even 24 or 30 volts is debatable. 

 

Do any modern can motors blow these days on 16v?

I haven't seen any yet, on my drag strip, but it's only been running for a month or so, with limited use because of the current situation.

I'm sure Tom K can comment.

I've blown 2-3 comms, with current inexpensive Chinese motors, on 24-27V.

I was just experimenting, to see how my high voltage run will play out, and sort of expected it.

I've run the Ram 857(?) powered Willys, of my late friend, Manta Ray Price, quite a few times, on 20+ volts, without a problem......other than not stopping at the end.

As far as modern motors, with hi performance comms, I have at least a few hundred, from my 19 years as serious G7 racer, and GM at Koford.

I'll eventually have some fun with those, on 16V, and beyond, when I get caught up with a bunch of more important projects.

[Tom Katsanis]

These motors are using Mura or tradeship comms I'm not sure which one it was now.

Original Mabuchi comm would'nt last to long especially on these motors I do remember reading that they ran Mabuchi buzz bombs (15r)on 36v they were cheap enough at the time that it did'nt matter when they blew.

Late last year there was a Magwinder type dragster with a 36d in it that was built in the 60's when I inquired the owner said he ran it on 24 volts he could not remember what time's it ran.

[Dave Crevie]

We will find out. I haven't opened the motor from the rail I brought last week, and we know that motor went poof. 

[MSwiss]

Tom, Don,
We ran the below 36D powered car of Dave's, two Saturday's ago.

It has a rewind, Dave did himself.

It ran 1.5.

It was plenty fast, but struggled for traction.

The sides/corners of the tires seem to be flaring a bit, so I suggested we sand them a bit.

In the process of sanding them, the motor smoked.

If I had to hazard a guess what happened, probably one of the (I assume) soldered comm connections melted.

[Phil Smith]

I'm surprised that even cheap comms blow from such a short burst of higher voltage. Given that the crappy Pittman comms survive it.

 

I really like 36D motors so it's neat to see these souped up versions. 

 

 

[Tom Katsanis]

I saw the build on Dave's car it turned out great.
It will be interesting to see what it does on higher voltage once he gets it sorted.

[Dave Crevie]

Thanks for the support, Tom. It will be just like the old days. You try things, and keep what works. It's how the magwinders were invented. We started

with aluminum rails, and went to mag when we could get it. Then started chopping up padlock motors to get more horsepower and cut the weight. I

have a s**tload of Pittman, Strombecker and Ram endframes that I cut up but didn't work out. Then someone discovered you could make the side

rails part of the motor, and things started to get pretty technical. 

[Tom Katsanis]

It was a very creative time Dave Crevie I don't think you will find teenagers today whittling out aluminium magnesium or even plastic to make stuff.

Update on my neo car I ran it the other day after playing with some parts & changing the crown from a 52 tooth to a 46 tooth gear.

I broke into the .7s & ran a .756 & a .769 on the pass after it.

As an fellow vintage slot drag car enthusiast, thank-you for rekindling interest in this fascinating aspect of slot racing.

 

I want to invite y'all to participate in the Slot Car Drag Race Proxy World Challenge. We offer an opportunity for many classes (29 actually) of slot cars including vintage and reproduction cars. We have invested in a switchable 16/25/37 volt system with big capacitors and massive amperage to be sure any car sent run to it's full potential.  I am putting effort and resources to make this a landmark event to grow the visibility of slot cars on a world stage.

 

We have classes and a format that we think you will appreciate. Please visit the webpage for full details. I look forward to hearing from you and especially for the honor of seeing your cars in the event.

Pablo is going to need some competition at the drag proxy for the Gansta Caddy so I have rebodied the Dragnoda with an old beat up Dodge body.

Gangster Caddy, Havlicek 36D

 

 

 

 

[Tom Katsanis]

Love it Pablo it should be fun now I know there are some hot 36d motors out there would be good if some more would come out to race.

[Don Weaver]

Looks like a Champion 707 w/ Arcos?

[Tom Katsanis]

That it is with a John Havlicek arm in it.

[nomad2race]

Awesome, Guys!

 

Here's another for "Can Rods" class.

 

It's getting black guide, foam tires and a bit more nose weight. 

 

 

[Isaac S.]

That is a Champion chassis! Definitely not designed for drag racing! Thanks for sharing!

[nomad2race]

Correct!  But is it fast, fun, vintage and consistent.  That is all that matters.

 

It is a little scary to run lighweight open wheel designs like this on a road course.  I do drive this one on my home track, it is scary fast on commercial tracks so it mostly sees the drag track at commercial raceways.

 

SO, Issac, show us what you are sending!  

[nomad2race]

For many reasons, we have decided to extend the deadline and reschedule the entry deadline to June 15th.

 

Good news! More time to build!

 

We will continually update this page our Facebook and our website as things progress.

 

As a thank-you to those who sent cars early, we will offer the option to have us run them as a test run. We will report results only to owners who may request changes to the cars before race time. We have also given the option of having cars returned at our expense, case you need them for other races before June 15.
