Default 1:10 Scale? Really?

I've done a bunch of number crunching, and if you compare it to a Toyota pickup, it's more like 1:8, so...

What's the basis for this comparison? What is the 1:1 scale size used to get to 1:10?

Thanks in advance for helping me burn time on a Friday.

every 10'' of any full size would equal 1'' of your scaler ...........



125'WB = 12.5WB ...............


1986 Toy 4wd p/u (to be real 1/10)

103''wb = 10.3''wb
112''wb = 11.2''wb


I think for the most part in RC the 1/10 number is used for size referencing, not actual size since most vehicles are not built to exact matches.





Just my thought if i understood you correctly.

Yup, I agree - just in looking at a bunch of numbers, it didn't make sense to me. If we compare to a Formula Toy, which is, I think, reasonable:

Wheelbase:
'2.2 class' max wheelbase is 12.5"; at 1:10, it's 125", but at 1:8 it's 100" - nice and close to the 103 to 106 that the FToys seem to be at (http://www.pirate4x4.com/forum/showp...52&postcount=2).

Width Overall:
Axial overall width is about 10"; at 1:10, that's 100", at 1:8, that's 80" - again, close to the 76" on this FToy: http://www.pirate4x4.com/forum/showp...34&postcount=2).

Weight:
With a finished weight of about 5 lbs, if you go 1:10 scale (10^3), it's 5 lbs x 1000 = 5,000 lbs, but if you go 1:8 scale (8^3), it's 5 lbs x 512 = 2,560, which is way more reasonable for a Formula Toyota (http://www.pirate4x4.com/forum/showt...ghlight=weight).

Rims & Tires:
2.2" is 22" at 1:10, but only 17.6" at 1:8 - a lot of Toys run 17" rims, and given that the Rock Lizards are also 2.2" wide, a 17" wide tire isn't unreasonable - and for comparison, a 18.5/44 TSL is 17" wide.

For tires, 5.25" seems an 'average' size for the 2.2's - that would be 52.5" at 1:10, but only 42" at 1:8, which is a totally reasonable tire size for an FToy.

I realize it also fits at 1:10 with a fullsize-based buggy - maybe this all just means that a Toyota is a 8:10 scale fullsize. So maybe it just magically works with both. Hehe.

The manufacturers decided to label 2.2 rigs as 1/10 scale because that's how things are in the other world. There is no reason or scaling about it as far as I know. Like Robob said, it is really used as a size reference rather than a true scaling.

When the 2.2 class was being developed the wheel size and wheelbase were roughly based on 1/8 scale dimensions of 1:1 competition buggies.
