Do brushless motors rust?

Good Morning all,

I've just joined the Forum - what a great place for a chat about model flying.

I've been flying mostly slope gliders for  30 years, on and off, designed a few myself but never published any plans.  Mostlyy, I fly off parts of the Black Mountains on the border with Wales.

Now I'm having a go at electric gliders, starting with the Easy Glider Electric using the brushless upgrade. I keep the model in a garage from where I can take it fully assembled to a field 5 mins walk from the house. But the garage can be damp in wet weather.  Is the motor likely to rust in these conditions and should I bring the plane indoors?

Hi, Bill, welcome to the party! Read - beginners start here, if you haven't already!

I don't know about motors going rusty, but the magnets and shafts, being steel-based, will! The damp will not do the woodwork any good, either, and what it will do to the electronics.... Keep them inside, in the warm and dry. If you are using lipo's charge them outside, just in case, but bring them in afterwards.

Hi Bill and welcome to the party.

I keep my models indoors, I'd hate to think of 'em getting cold and R/C (receivers, servos) gear and damp/cold isn't an ideal mix.

There's also a good argument for not letting batteries get to cold most get very lazy as the temp approaches 0 and while I've never experienced it I'm told serious freezing conditions can kill them (Timbo will know more) also I would have thought that damp contacts on any battery would be a serious No No

Electric motors do rust.  Some of the cheaper far-eastern ones are delivered with disappointingly pre-rusted iron laminates.  I know this as I always have to take motors apart as soon as I get them - don't know why I do this, maybe I should see someone about it.

But, more to the point, all your other hard earned gear is susceptible to moisture too.  I can't keep mine in the house either, so I keep a dehumidifier running 24/7 in the shed.  Not brilliant for the carbon footprint, I accept, but neither is regularly replacing a lot of manufactured electronic equipment.

The devil you know....damp is insidious stuff, it gets in everywhere. (Especially when the darn rain doesn't stop all weekend!)
