Cheap Fans !-I had call to change a drill motor cog today which I havent done before and only observed
others having a go.
I'm sure there is a special tool for doing this but I muddled through with somes wedge shaped snips to ease
the cog up until it got quite stiff and then I heard a crunch!.
Eventually I got the cog off with the aid of two washers and two screwdriver levers but needed to ivestigate the crunch
so a total strip down was required.+-
It turns ot the motor fan on these motors are glued onto the stator magnets and are quite easily dislodged-like
probably in battle and are pitiful in design terms, anyway nowt to do but glue it back in place after cog was fitted
and see how long it lasts-I have had a few burnt out motors in competition and I'm just wondering how many
were due to the fan coming loose and clogging up the motor and making it work too hard.

Talking of fans and motors-I'm finding it hard to get hold of like for like ESC cooling fans for my Cytron 60
so if anyone has a complete esc for spares I would be interested.
