waterproofing idea, good or bad?

[suhbliem]

I had a scary run-in with a massive hidden puddle the other day at the park, luckily nothing was damaged. This has prompted me to start on my next project of waterproofing the servos. I've read the various methods to water-proofing and have decided combining some of the methods would yield the best results.

for the servos I plan to take the casing off and fill with silicone grease. re-assemble then dip in plasti dip. After dry I will re-attach the servo horn using two greased o-rings

as for the reciever, I did not want to plastidip the whole box with the servo connections on it since I will probably change some part of the setup in the future. therefore I opted to do a balloon/grease method. I plan on putting a balloon around the reciever with all servo/battery connections in place and fill the balloon with silicon grease and zip tie firmly.

finally, I plan on sealing the reciever box with some silicon kitchen caulk, gasket style, was also thinking it would be a good idea to fill the small space where the on/off switch is mounted with silicone grease, just in case.

what do you guys think about this plan, are there any problems that I may have over-looked?

Well your idea sounds good. I waterproofed my maxx for snow driving. All I did was take a bunch of balloons, double balloon all of the servos and cut out the tops where the horn is, and zip tie the ends off. For the battery, I double ballooned the battery holder, zip tied it closed and zip tied the battery holder right onto the front shock tower. I cut the neck off of a balloon and put the switch in it and zip tied both ends closed. I took the reciever, double ballooned it, double zip tied it, and just put it back in the reciever box. It worked perfectly in the snow but I tried to keep out of big puddles as much as possible

I used sensor safe rtv on the rx and battery box seams. Same with the servo seams, an o-ring under the horn and rtv on the horn screw. Looks stock, sealed tight and never had a problem. Filling balloons with grease just sounds like a very unnecessary mess. I wouldn't trust balloons anyways.

thanks for the responses guys, I ended up getting clear silicon kitchen caulk to seal up the servos and battery/reciever box, turned out well as I can remove the boxes and the silicone stays in place like a gasket. used o-rings and plumbers silicone faucet lubricant for the servo output shaft.

that was yesterday, today it is very wet outside. I drove around splashing through puddles and the little bit of snow left up here in michigan and haven't had any problems with water leaking into any of the electronics. very happy. I mainly did this not b/c I'm going to look for water to run through, but just in case I run through another massive puddle at full speed by accident, at least i know my $300 in electronics will be safe (pretty sure i sprinted 100m in 5 seconds to get to my car when it was in the puddle with no sealant the first time)
