Thanks G-Bob,  I was wondering at first if my post had been lost ( I was having internet issues at same time I added that), sorry  I stuck it in wrong area. cant twist your arm on the lancer can I ?   Is the Dubro fairly similar in size dimensions ? Maybe hold it for me and see if anyone out here in blog land might offer a Lancer up? ( I know their rare and I am kicking self for not snagging the one on ebay  )

Here is a lot with 'something different'. Is that a wind-up motor ... I'll be stuck with

Does anyone recognize the motor shown above?

[Gator Bob]

So there is talk and even development of Monster and Multi Motor cars ....  "Dude, that's really heavy ..man, like let's do it just cause it's fun bro"

 

Who'z going 'Big' ?

 

In the mean time ... A good old car show and vintage drags keeps the nitro flowing.    That orange 33

If I have time I could go big or multi motor

Nothing definite though and just wild speculation in the team motorhome

[boxerdog]

I'm definitely "going big". My first attempt is a Henry J. Hopefully will have a "multi" done as well. 

[Pitt Man]

I'll go big

 

Dunno if it would be multiple inline open frames motors or a DC105A (or two), but I wanna play ,too

 

I have a 12" plastic toy school bus on the way, anxious to see what will fit in it.

 

It may be a bit narrow, but big meats stickin' out might look intimidating.

 

Between "luxury" on the bus and the spelling of school on the box, I got a good giggle. 

 

 

 

 

 

[Gator Bob]

Nice !    Keep the lighting ... please.

 

"Hey... what the hell do you think your doing ... you can't pass a school bus with the red lights flashing" ..

At long last a Pittman Boatmaster arrived at HQ and a DC95 will be in the mail system soon...

Didn't know what to expect from the boatmaster but it's soo cool

Have no clue what these are gonna end up in or any ideas right this minute but one may make it for the 3rd annual race

[boxerdog]

Still working on Monster Motor stuff myself, it got back burnered for a bit. Got some huge-but-slow motors. Any pics, Paul??

[SlotStox#53]

Hi David, I have a quick one I took of the boatmaster, it's not the best but will take a better one later

Had to take the front plate off to have a look inside. Massive 5 pole beast of an armature with long brush arms with the usual spring & plunger. Put it back so I couldn't be tempted to strip it down

[boxerdog]

Very nice!!

Hi everyone just posting my builds for the 4th rods & rails drag proxy.1st up is my rail w a ram 850 motor that has lost it's arm i've put the motor on a diet taking a bit of meat out of the end plates i've ground the top lams similar to how Gene Husting did in his r&c articles & took a bit of a cut on the bottom lams & reshaped them as they come back into the motor on arm end similar to a ram 857 & have either a ram 7 pole arm for the mpc dyna or a pittman 5 pole arm to try in it.I have a what i believe's a kemtron brass tube chassis w about a 8 1/2 in wheelbase that i have made a thin brass sheet body for i have hung a little 3 bar style cage off the rear axle the tires measure 10 mm x 34mm sponges on aluminum rims fronts measure 4mm x 28.5 on aluminum not sure what brand.I'm just at the point of mounting body painting driver & hopefully i will be right to run.My next car is for the stock 36d class running a royal bobcat motor (somthing tells me i should have built a Pontiac) in a scratch built sidewinder frame made out of 2mm solid brass with a couple of 4mm cross tubes for a little strength a tube drop arm with a hook stop 1/8 ball bearing rear with i think k&b rims & unique lemans tires.I've been a bit more slack on front w a 3mm axle plafit rims tires off a bantam altered kit & half some amt 12 spoke wheels inserted running no bearing.The ratio is 3 to 1 as the rules say & i'm putting an amt 62 t bird body on it i've got it sitting reasonable low with only some paint & detailing left to do (as long as the chassis passes tech fingers crossed) i will put up some more photos as i make progress.
Thanks Tom

Very nice builds, Tom.

 

I particularly like the brass body on the rail.    

 

The new 36D class should be lotsa fun with everyone running to spec. It'll make for tight competition.

 

I'm behind on my builds this year with my recent move, but I'll catch up.

 

I built an "industrial strength" wheelie bar this year on my ridiculous monster motor class car, Fireball 95B. Last year the piano wire wheelie bar allowed the beast to "porpoise" down the track as the wimpy bar setup would repeatedly flex and springboard back as it deflected which would then allow the pickup braids to lose contact.

 

Also added some killer 12 AWG lead wires and will be adding a .016 aluminum sheet body along with a full set of aluminum screw fasteners to help reduce the one pound+ running weight.

 

Hopefully she cut sub one second runs this year!

 

[don.siegel]

Wow, Pit Man, missed this one last year - a work of art. 

 

Ditto on the nice brass body Tom, and some good looking rails! 

 

Don 

[Tom Katsanis]

Hey pittman thanks your 95b beast looks cool is it the one on the proxy footage from last year thanks Don it's got a few ripples in the body but this thin gauge stuff is hard to work with the shrinker just shredded it.

[Pitt Man]

Yup, that's the one Tom, the one arc welding the pickup braids and banging the rear of the chassis!

 

Here's a couple shots of the motor.

 

It started life as a Pittman DC95B, but all that's original now are the lamination stacks.

 

Inside is a 13 turn dbl wind R/C Venom Fireball arm (originally intended to run on 7.2 volts) and brush endbell. The end plates were machined from micarta on a Bridgeport mill, the clunky alnico magnet replaced with a N52 neodymium magnet and ball bearings on both ends. All said and done it is a REDICULOUSLY powerful motor! Quite a mix of 50's and modern tech parts.

 

This was the 3rd and most likely last of it's kind made. Hopefully the other owners will post shots of theirs, built with aluminum end plates.

 

 

 

 

 

 

 

[SlotStox#53]

Did someone mention monster dc95 padlock motor with aluminum endplates?

Apparently the 7 turns single wire r/c arm = .063" = 7 turns of 14# wire

Still to make a car for this beast, sounds lethal under power.

[SlotStox#53]

Out of curiosity Pittman, how many teeth are on those outer gears/pinions running off the motor?     

 

Gonna have to work out a suitable ratio for mine considering I'm toying with an idea of putting this inline In the style of the 60's front engined rails. Time for 1/8 music wire rails

 

Any idea if the modern slot drag crown gears would hold up to the torque of this WMD?

[Pitt Man]

Hi Paul

 

The 4 big gears are all 62 tooth, one 39 tooth on a jackshaft meshes into one of those 62's, resulting in a 1.59:1 ratio.

 

Hopefully, modern crowns would take the torque, but the trick would be to build the motor mount/axle carrier just as rigid as possible.

 

I not sure which I'd use, Parma or the skinny toothed Sonic drag gears, I'd think the wider toothed Parma might be a bit tougher. The more I think about it, I'd bet on the Sonic going bye bye on the first launch.

 

The good old brass 2:1 K&B bevels may also be a good option.

[SlotStox#53]

Ah, hadn't even thought about good old bevel gears!

2:1?? I gots a set of those off of the original Inch Pincher.. hmm..

Time for a bomb proof motor bracket/rear end.

[Tom Katsanis]

Hi guys i must say the workmanship on those motors is exceptional i'm very impressed & they sound like they are absolute monsters.
Tom.

[slotbaker]

Geez Paul, if you run that 95 as an inliner, you might have to put an out rigger on the side from torqing over on itself!!
