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
