Well I swear... I swear I measured that shaft on my 60 X-Cell and it read 5 mm! But when the hex adapter for a 5 mm shaft came in it didn't fit blast it all! Too small. So looks like I didn't measure it enough times... the shaft on an X-Cell 60 is 6 mm in diameter, not 5. Grrrrr! [:@]

Anybody flying a 30 or 50 sized bird need a hex adapter? [&o]

LOL!
