With the onset of the rainy season I decided to try a bit of weather proofing...
Two hours, much Duck Tape, some plastic cartons and a tin of spray paint later, a reasonable looking, stealth enhancing, screw-on motor and wiring splash guard:
Some testing showed that it keeps the muck out but, perhaps not supprisingly, it limits the cooling airflow around the motor too much
The addition of the skirt bearing on these newer Turnigy outrunners does not help the cooling, because the bearing mounting cause a restriction, less air is drawn through the motor when it is spinning to help cool the stator and magnets.
... so back to the drawing board, ...maybe some forced cooling required ?EDIT:
Just removing one side of the shield improves the cooling a lot, I think there will be no problem now during hard use in our English climate
On a different tack... I recently aquired a 51v 3kw switched mode power supply.
This is a real beast. When you first turn it on, the inrush causes all the lights in the house to flicker
When I work out how to tame this thing a bit, I should be able to charge my LiPos from empty in 30 minutes
Of course you need somewhere safe and dry to perform this stunt, so -cue the new metal LiPo charging bunker......
