HO scale Math?

[cudaken]

Dragged my track out after 12 years plus. I speaking with a E-bay seller that said my HO track and cars are 1/68th scale.

I was wondering in scale how big my track is.

Tack is 1404 inches which = 117 feet.

Do I take the 1404 inches x 68 = 95,572 divided by 12 = 7964.3333 divided by 5280 = 1.5 miles
                                                          Or
117 feet X 68 = 7956 divided by, Oh never mine!

Looks like I have 1.5 miles of track.

OK, some how I figured that out. Now a real dumb ass question.

Does scale effect time? When I had the track sat up before the Daytona corved the 18 foot rear straight away in 1.4 seconds.

Lets see, 18 feet X 68 scale = 1224 scale feet divided 1.4 = 874.28 feet per seconds X 60 minutes = 52,456.8 MPH? That could not be right, is it?

No wonder we use to get dizzy when we raced the track.

Daytona is a older Aroura body on a (I think) with a AFX 440 Magunum chassic and it was modified.

Ken you've been dippin in the eggnog haven't ya?

[BigBlockSam]

hey Ken
  you got way to much free time on your hands. 

[cudaken]

 My free time, build $12,000.00 440's that take a s--t after 85 miles! Next question?

                             Cuda Ken, looking for answer again, and again and again.

having done this math a # of times I generally come up with around 1000 mph scale speed
the other way to lok at is if a top fuel doest the 1/4 [1320'] in 4.5 seconds at 300+ mph & you can cover 1200 scale '   in 1.4 seconds you are travelling at close to 3x the 330 MPH the fuelers do
I run highly modified Rokar /Lifelike chassis which are faster than anything else I have found so far
BTW HO scale is 1 /64
& yes I also have the Daytona AfX

Lets see, 18 feet X 68 scale = 1224 scale feet divided 1.4 = 874.28 feet per seconds X 60 minutes = 52,456.8 MPH? That could not be right, is it?

try deviding by 60.

[cudaken]

Cont. Rod's were never Trq'd to spec's. No warranty either!

Mark, there seems to be a lot of that going around lately. Let me guess he had APR Rod Bolts.

Neil, what is the math for the MPH, was Andrew right and I divide by 60? I have never heard of the Rokar /Lifelike chassis before, but then again I have not been in a hobby store for 15 years now. How much to build me one Just kidding for now. But, some details would be nices Neil.

Soaking the AFX's 440 Mags to clean them up, is Cam 2 OK, I just dropped one in the beer.

ummm...what the hell are you guys talking abut?

[Old Moparz]

Here is a site with scale conversions, speed & sizes:
http://www.spec2000.net/rr_site_pages/rr_scale_dfn.htm

From that site:
SCALE SPEED equals actual speed multiplied by the SCALE RATIO. A model traveling 20 feet per minute is moving at an actual speed of 0.227 miles per hour, equivalent to almost 20 scale miles per hour in HO Scale (1:87). Most models travel too fast; the worst being run at over 300 scale miles per hour. The conversion equation is:

Scale Speed (mph) = 1/88 times Speed (feet/minute) times SCALE RATIO

Many people use a SCALE MILE (often called a Smile) which is shorter than a real scale mile, and others use SCALE TIME, usually 5 to 10 times faster than real time, to account for selective compression of model railways and the high speeds of model trains. Here, Scale speed (sph) = Smiles divided by Scale time.

Ponch was looking forward to a thread about ho's.

 Boy that made my head hurt. Will try the math Sunday.

  I didn't really try to follow it either, but the site seemed legit, so I'd let you figure it out. I love the model railroad & slot cars, & i used to have some kind of conversion chart when I was a kid. If I know me, I probably still have that chart, but only a higher power would know where it is. I do know where all my AFX & Aurora stuff is & now feeling like getting it out of some boxes to set up. Especially a train under the tree to freak out the cat.

the fastest slots are supposed to be the Wizzards , out of my price range
the Lifelike are easy to get , the new style is fast but totally un modifiable
the old stlye lifelike rokars are highly modifiable & run 25% faster then a Super G +

1/64 was S scale. HO stands for half O. O scale was generally regarded to be 1:43. My old Aurora mid-60s manuals all state 1:87 for HO which makes perfect sense as half of O scale.

Sat up a small track in the family room last night 11' X 3'. Wife did nothing but bitch. There a shock right Took me a while to sort the stuff out but did get it up and running. Fast car's, well lets say they are worn out cars and will not move. Just sit there and spin there tire, pick ups are so worn the guide pin seems to me hitting the bottom of the track.

Some of the slower cars where still in good shape, makes me wonder why I need faster cars Did Finlay find a local hobby shop, seems they are going the way of the local speed shop. Just hardly any left. They say they have some AFX tune up kits so I will be heading down there today when I go to work on Allens Challenger.

On a funny side note, after I got the track up and running, wife came out and played with it with me.

Neil, thanks on the heads up on the cars. I will look at the Life Like cars, they sell them at the hobby shop but right now I be happy if I get the old fast ones running. Dam tires either dry rotted or turn to goo. I think it was the liquid traction that did it.

My other hobby is model trains and the scale I model mostly in is HO.  If the standard for slotcars is the same as for trains then HO = 1 : 87.    S = 1 :64   O = 1 :48 and G = 1 : 23  g has a few varients but its roughly 1:23.  I dont remember N and Z scales off the top of my head but they are too small for me to mess with anyway.  My wife likes N cause its "cute" but let me tell you its murder on the eyes when trying to work on the stuff.
Happy Hollidays to all.

Hey Ken,

I'm motivated now & planning a trip to the attic. At least mine are stored in the finished portion where the heat & cold isn't a factor. I hope the tires held up on mine, but some are silicon ones that always lasted & should be in good shape & better than the dry rotted, foam ones. (Maybe?) I don't think my wife will bitch about it though, she could care less. I know she won't play with them, but if I can get her to play with me I'll be happy.

 Old Moparz, glad to see I am not the only one getting the bug back. Track got a little bigger last night, my wife looked at it today and said "that's cute". Now if I could dump the love seat, but the Wolfhound would not have her places to lay.

Dog in the PIC is not real and not the dog I am talking about. Note cheap stereo system as well, not the one I brag about.

Dam Old Moparz, thats not HO scale, more like DD scale!

My cars are Tyco 440 X 2, just found that out today.

Hey Ken,

I didn't take the slot cars out, but I did take some of my HO trains down from the attic & set them up. Some scenery, enough track to circle the tree, one locomotive, a few cars, & a caboose. My daughter went nuts over it, & keeps asking if it's okay to play with them. Sure she can, she's not the destructive type & I hope she likes them as much as I did when I was a kid. She's already gotten out some matchbox cars to go with the layout, even though they aren't the right scale. 

I was wondering if you were going to check out the links I posted. 

Bob

[cudaken]

Well I final did, guys don't know what they are missing and good thing Troy did not look there either. Getting a HO race track question would be the first.

Besides your link, this one all so got me going. Look under custom, I want that track.

Maybe re thinking the track idea and moving to to the Mopad. Maybe a little smaller track at the house in the garage. Get rid of the 2 69 and 1/2 6-pack hoods, 2nd gen Charger hood with the blower hole, weight bench I have been try to dump for years and some other crap might be able to do a good sizes L shape track.

While looking for something else on the internet the other night, my searches put me on the hoslotracing.com website. There's a history of HO scale as it relates to slot cars somewhere in there that I found pretty interesting.

HO scale is indeed 1:87, except no HO slot car set was ever modeled in that scale. The first ones were developed in England at OO scale (approx. 1:76) and Aurora bought the rights to them and sold them here but marketed them as HO because OO scale was never popular in the U.S. When Tyco brought out their line of slot cars they made them slightly larger at 1:64 (which is S) but marketed them as HO. Aurora eventually enlarged their chassis to the 1:64 size but continued to call them HO. So, in a nutshell, HO slot car sets are about 1:64 but are not really at HO scale. It's all in the marketing.

Sorry to dredge up the past but I read all that and remembered this thread and thought, why not.

I talked to ken about a month ago, is now into trains, the road runner sits outside and the train track takes up the garage.  He has not been on the site in a long long time.

[Slowpoke]

The rokars are good I raced ho's for 10 years and all ways liked them
but switched to wizzards modified tycos for the last
three years. a top car in our class cost about 120 to 150 dollars.
although an all out neo car could set you back 300 to 400.

Under a cover, hopefully.

nope! said he hasn't started it in over a year
