Waterproofing --

Unfortunately, most electronics for RC models are not waterproof - this can lead to damage if you run your ride in wet or snowy conditions. Some companies do offer waterproof ESCs and servos, but if you're not ready to pony up for new electronics, here are some tips for DIY waterproofing:

- BATTERIES - Stuff your batts in a balloon with the leads running out of the open end, use a rubber band or zip tie to seal the end, then apply thick marine grease to the area. This works for power packs and RX packs.

- ESCs - Use shrink tubing and apply thick marine grease on soldered connections. Also apply thick marine grease around the area where the servo lead exits the ESC. Do not wrap the case or electronics - ESCs can get very hot (and can melt anything used to wrap them). They need access to air to stay cool. You might consider creating a lexan splash guard to help keep excess water from reaching the ESC body.

- RECEIVERS - The same waterproofing trick for batteries also works well for receivers. Stuff your RX in a balloon with the leads and antenna running out of the open end, use a rubber band or zip tie to seal the end, then apply thick marine grease to the area.

- SERVOS - Apply thick marine grease around all seams, screw heads, and where the servo lead exits the case. Also, apply thick marine grease around the output shaft (it helps to remove the servo arm before doing this). For a more permanent and durable waterproofing, use clear silicone caulk instead of grease around the seams, screw heads, and servo lead. Don't use caulk on the output shaft - the reason should be obvious.

- TRANSMITTER - If you have decided that you can gain more speed by using a hurricane as a tail wind, then you will need to protect your radio as well as the onboard electronics. The simple solution is to use a small trash bag - just stuff your TX and hands in the bag and you're good to go. If you use a clear bag, there's a better chance that you'll be able to see the display, but there's no guarantees once the bag is wet.
