Running in the wet isn't a prob just use the ballon trick as listed above, use tape to seal your servo and put a dab of greese where it opens for you to put on the servo saver so that it is water tight. You could also spray lots of WD40 over the exposed metal parts like the cvd's the axcels the diff outlets the turnbuckles just to make sure they are a little more water resisitant. Don't forget to clean the car after running though. NItro fares better in the wet then ele because most have sealed radio boxes and all you have to do is seal the servo's and your ready. Ele still reigns sepreme though.
