Hi everyone, i am a absolutely new to Rc boating and i have 2 - trailblazer 1300bp stock both with problems - there both quite old and been given to me by a family member. Boat 1 worked fine, then took a flip and took in alot of water on all parts inside. Now when attached to the battery it just beeps single beeps and does not connect to the remote or has any response. Boat 2 connects to remote but the throttle turns on at full straight away and has no throttle response or control, although i can control the rudders - this worked the day before as normal but now doesn't. I am using TopEdge AFM3 remote. Can someone please help, please note I'm a total amatuer so can you dumb it down, il be ever so thankful. I am assuming i just let Boat 1 to dry out - i have taken out the reciever to dry, everything else is bolted in. I'm not sure what the ESC is and I'm not sure it is damaged. Any help? Thanks
