Prop Edge 540, Extra 300, and Extra 330 number question

[Derek]

These 3 planes all have numbers in the name. Is there a significance to these numbers?

For example, when referencing a 700 class helicopter, we all know that a 700 class helicopter will have 700mm blades. A 600 class helicopter will have 600 class blades.

What about these three planes?

They seem the same to me, still need a big barf bag!

I appreciate that, Dave! Thanks!

The numerals included in these names are nothing to do with RC modelling, but the actual production names for the full size aircraft. I can find no correlation between the planes specification and the names but there probably is somewhere in the original design.

I was sure that the numbers on these planes had no relation to rc. I was just using the rc reference as an example. I appreciate the time you guys put into this for me.
