Default 3.2mm Collet on 3.0 mm shaft

Okay searched and read till my eyeballs are buggin, This is probably one of
them Newbie things everyone but me just knows or assumes never asking about it.
So being a Newbie (less than 10 flights) and having a need to understand, Here I go...

At present I'm running a Brushed Speed 600 motor in a 2m Electric Glider,
YES, Having Great Fun Thanks!
But I'm feeling alittle underpowered and started looking at Brush-less... Thats where this started.
MOST if not all Brush-less motors I've looked at have output shaft diameters of 3mm,4mm,5mm ect...
Most if not all Brushed motors in the power range list 3.2mm (1/8 in).
So after looking a little I find a Brush-less I like having (according to listed specs) a 3mm output shaft.
So do I now need to replace the 3.2mm collets or is the difference just in my mind?
I mean I look at a ruler with millimeters and can't really JUDGE 2/10ths of a mm,
But I know it's there. [sm=spinnyeyes.gif]

Would Appreciate knowledgeable comments, Thanks

there is actually a big difference between the two,2/10ths of a mmm is 8 thou',it is too much for a collet type adapter to take up,you WILL need to get a 3mm one,i have a similar problem with an edf model i am building except i have got to get an adapter made.

Thanks for the comeback Bigchap,
Wouldn't you know just a few minutes ago I stumbled
apon someone that makes both 3.0 mm and 3.2 mm shaft adapters,
Which basically answered my question as well.

Ya know a guy could probably make alittle money if they
could design and manufacture a !QUOT! UNIVERSAL SHAFT ADAPTER !QUOT!.
But until then I guess I'm getting a few 3.0mm's to hold me over.

Again thanks for the reply
