ok so ran the p4de on the beach yesterday. near end of first 2s pack i noticed i had no reverse. stopped truck doused it in clean water and let it sit for a bit. also threw some new batteries in the controller.
put 2nd 2s pack in and started driving again. everything was back to normal. then probably 10 minutes into the pack something went wrong. hit the brakes and heard a clunking sound. drove truck over to me and heard a high-pitched whirring noise. then no forward or reverse. rinsed truck off with clean water and when i got home washed it off and drowned the truck in wd-40 because i'm not sure when i'll be able to do a full tear down.
any advice on what my potential problem could be? I'm thinking something gear related or slipper clutch issue.
thanks and sorry for all the noob questions but this is my first real rc.
