.........and comparing a .40 to a .15 isn't what I'd call fair either.
Hi Dave,
that comparison was already done when a .15ci engine was quoted using a 10x6 - the extropolation was linking that prop to what sized engine normaly would use one.
The unfairness lies in fair placing a 10x6 with any .15ci engine and then saying it does 10500 rpm in any usable form.
By democratic vote here, it just ain't possible.
