Protecting electric engines from water
I have a Hobbyzone Mini Super Cub and in the future I might put floats on and I was worried about crashing and ruining the engine

RE: Protecting electric engines from water
Follow up question got you electric float guys, I asked this in my Rufe thread with no response
Us Nitro guys for years just put the Rx in a plastic bag to protect it from minor dunking and spray that might seep in the fuse,
The question I have is,
Do you think putting the ESC in a bag reduces it cooling properties enough to be a problem?

RE: Protecting electric engines from water
Some of the guys that I fly with use Corrision X ( I think that is the right spelling. 
) I usually spray the receiver and the ESC and let it drip out the access then mount it in the plane.
to answer your question scale... it would not be a good idea to put a ESC in a plastic bag. ESC need the air to stay cool.
Hope this helps!

Scaleonly4me:
Modern ESCs are super efficient and only get slightly warm. Most, if you'll notice, have dispensed with using a finned heat sink since it is not necessary.
A plastic bag is unlikely to cause any problems.
Another trick that will help: use an ESC rated for twice the current you'll be consuming.

Well, the plastic bag didn't really work very well, I dunked the plane and it still got in
What do you thing of sealing the ends with silicone of a ESC like this?

It seam the heat escapes from the shrink wrap anyway, not airflow though the ends.
I was thinking of doing that and adding a couple small heat-sinks I have laying around
opinions??

RE: Protecting electric engines from water
Use electronics-grade silicone if you do it. The commercial silicone RTV has acetic acid in it ( it smells like vinegar) . Acetic acid is baaaad on the copper circuit board connectors of your ESC.
I'm leaning to a nice greasy shot of CorrosionX as being a more practical solution to the potential problem.
