For a winter snow bashing setup I am using a Mtronics ESC. They are waterproof out of the box. For the batteries I just use saran wrap and do a good job wrapping the lipos up. The servos are listed as ''water resistant'' so I just dont worry about it. I'm not driving it under water. It just get splashed. For the receiver the old fashioned balloon works the best IMO. I just dont worry about the motor. But when Im done running I give it a shot of motor cleaner to get the water out and then a drop of light oil on the bearings.
I have a friend who uses dip sealant on the servo also. Works well, but it looks like a PITA if you want to clean it up.
I can't decide if its more fun
to make it...
or break it...
None of you guys have heard of CorrosionX ..... all the gas boater guys use it. It is used same way as dielectric grease ... the difference being it is not a grease more like an oily spray that adheres to electronics but is totally electronics freindly.
The mamba Max ESC already is waterproof if I'm not mistaking, the internals are covered with a layer of some sort of varnish. I'm not saying you should submarine it but I drive my car on kinda wet tracks and nothing happened :-) so far.
