Scale question

Hi. I'm totally new to all this. I actually got into this because of the pics I saw of Smiggin's . My question is what scale do you make your buildings? Is it 1:10 like my truck? I found a scale calculator on google and it seems like my stuff is coming out huge. Any help you guys could lend me would sure be appreciated. Thank you.

Very few trucks are actually 10th scale. Most are closer to 9th, like the SCX10III Wrangler for example.

Most of the buildings in Smiggin's Folly are 9th scale if I recall correctly. Not sure why you'd need a calculator on Google, all you do is divide by the scale you want to work in. Say a building is 90 inches tall in real life. Divide by 9 to find it's height at 9th scale in inches. Spoiler alert, it's 10 inches tall.

Yes, like imthatguy said, defiantly go 9th scale, or you'll kick yourself later. I think they do tend to get big, that's why most scale courses have small buildings like one room cabins and the like. I know Smiggins has a great outhouse...

It's great until you've used the main floor.

So most builds are at 9th scale? I?ve been making stuff (little accessories) for my deadbolt and was using 1:10.

Most builds that are based off the Tamiya Hilux, Axial Wrangler, among others. Most of the Traxxas trucks are 9th scale too. Measure the wheelbase, body dimensions, etc. to discover what the true scale is.

I have a Deadbolt and I put it on top of a 66 Bronco in Photoshop. All the features align perfectly. Then I got the actual length of the Bronco body and divided it by the length of the Deadbolt body. It's an almost perfect 1:9 scale rig.

Another thing you should look at when scaling things is the real proportions of the wheels and tires. Our eyes... and brains... can distinguish really small differences in measurement. That's the reason why you will notice if someone has gained weight, lost weight, had a recent haircut, a shave, etc. when it comes to scale, wheels and tires are the first giveaways that you are looking at an RC. They're just off... The real nice builds that revolve around the 1/9 scale look so real because, (specially if they're Jeeps, Tacomas, or modified 4x4s) the most popular tires and wheels used are 17-inch wheels with either 35, 38, 40, or 42-inch tires. The 1.9-inch RC beadlock is a close match to the dimensions of a 17-inch wheel in 1/9 scale. Add scale tires in 3.85-in, 4.19-in, 4.5-in, and 4.75-in, you get the perfect scale equivalent of 35, 38, 40, or 42-in tires on 17-inch beadlocks.

Furthermore, the SCX 10 axle width gives you a sidewall to sidewall measurement which is equivalent to a widened Dynatrac axle.

Another example is the RC4WD Defenders. The Defender 110 is called a 110 because off its 110-inch wheelbase. The RC4WD 13-inch wheelbase = 1/8.46 in scale. the 1.9-inch beadlock multiplied by 8.46 (the scale) = 16 inches. Which is the rim size of Land Rovers.

That's another reason why the Defender 110 scale RC looks so real when detailed and accessorized the right way.

Wes covers the maths calculation pretty good in the video above. And as ppcsurfr above said, is extremely important to a build overall correct look that the tires and wheels size match what you are trying to replicate (wheel diameter, outer tire diameter)

Sometimes RC bodies manufacturers adapt the wheelbase of the model so it fits the most standard chassis sizes, so I tend to not only use the wheelbase as the reference in my scale calculation. Specially when I have doubts that the body is not perfectly scale or some proportions are off.

I prefer to use something that our brain uses as a reference for proportion on that specific car, such as the fender height, or door height, or overall model height. I choose something that looks right on that specific body.

On my Escort MK2 build I measured the door panel height, and used some blueprints of the actual car found on google to figure out the scale compared the actual car door height.

Then I choose another different measure, like overall height or wheel arches size and do the same calc. Can also be wheelbase, width, to see if it all matches up ok. Then you get a good ballpark for scale when you want to find the right wheels and tires.

For wheels, also take into consideration the apparent wheel diameter is roughly 1" larger than the actual wheel spec. So if you have 17" wheels, the visible part actually measure about 18" because of the wheel lip that makes sure the tire stays on the wheel.

I do it exactly as @wesmade does it - I choose and assemble axles and wheels and tyres and then measure from the outside of the left tyre to the outside of the right tyre (A). Then I add whatever fender overhang I want (B) - typically ~ 5mm for modern trucks, and 10mm for vintage trucks. Use blueprints to get the right measurement.

I also only ever use blueprints - photos have perspective and are therefore not suited to realistic modelling.

Agree with everyone on here but one thing to add to @Fourth Protocol

Careful with the blueprints! It's probably because I'm a cheapskate and only use free online files rather than paying for quality... but many of the images that claim to be blueprints are really not accurate at all.

I think the key is also to use multiple sources- blueprints, photos (for detail/reference, not patterns) and a really well documented 1:1 resto blog will often give you key information. And sometimes it really helps to find an actual reference vehicle on the road.

And I normally try to aim for 1:9th scale where possible (to fit in with the Hilux) though sometimes the axles just won't allow it.
