Hi Chaps,
I have just fitted the new turnigy motor to my F18 fan housing & it seems almost impossible to find a 4, 5 or 6 bladed fan & adaptor to fit onto the 3mm shaft !!
Anybody know of a good source for EDF fans or completed fan + housing units that might do the job please ???     Don's wicked is the only one that appears to have the bits I need but I really want it quick  
Advice appreciated, thanks

Thanks Dizz.     i have gone square eyed looking over the GC stock but they have no matching shaft & impellers in stock @ 64mm.
Emailed 3 different RC suppliers today to ask & got the grand sum of 0.00 replies
But, I put my thinking head on (difficult when one is terminally stupid) & have sorted it
I had an impeller and shaft for a 2mm motor shaft which was a press fit.   I carefully drilled it out to 3mm & then drilled the sides, tapped them & inserted grub screws.   Spun it up to full power & it seems fine - no vibrations

For future reference, GWS make a 3mm shaft adapter for their 64mm fan unit's, available from RC-Castle.
