Sorry to hear you're having problems with your Nitro Hammer. I own two of them and haven't encountered any problems like you're describing. You have to get an awful lot of water into the hull to get the radio gear wet, check to make sure you aren't getting water in through the rudder mount, trim tab screws, or stuffing box. I don't think I've ever seen a truly water-proof radio box and you can easily tell by looking at the Nitro Hammer radio box that it is not water-proof, though it may be water-resistant (whatever that means). I've noticed water in my hull after running before, but I always dry it out between runs. You might try brushing some of that tool-dip stuff on the underside of the servos, I've done that on my sailboats before and it works well.

I use Aeroplate to waterproof my servos and recievers. There are other brands available such as Corrosion X and The Stuph. Even with that, I still put my reciever in a bag of some kind and seal it with a zip tie. Disposable baby bottle liners work great and are cheap. To soak up any water inside your radio box, put some paper towels or a tampon inside. Yeah, I said the "T" word! Some boaters even have seen known to use condoms to wrap their recievers in, the non-lubricated ones of course.

Here is what i have done to water proof the radio box

see the picture below

Cut an rectangular hole on the radio box lid.
Cover the big opening with a transparent plastic sheet (approx. 2mm thick)
Cut a rectangular hole on the transparent plastic sheet for battery replacement.
Use screw and silcone to seal and secure the plastic sheet on the radio box lid.
Apply epoxy to completly seal and glue the radio box lid to the bottom tray.
Use water proof tape to seal the battery replacement hole or use another plastic sheet to cover the battery replacement hole.

Apply some silicone sealant at the exit of two servo rod and wrap with cable tie (see picture)

I also wrap the receiver with the balloon and cable tie.


My boat flips so many times and so far the radio gears are OK.

One more - apply sealant on radio box of the hole that the receiver antenna pass through.

Here are the other modifications i have done.

1. Change the plastic rudder to metal rudder.
2. Use metal propeller.
3. replace the 75cc fuel tank with 120cc fuel tank (longer run time now).


Modifications in the future:

Change it to surface drive.

WHERE CAN I BUY THE HOP UP PARTS FOR THE HAMMER LIKE THE METAL RUDDER AND THE 120cc FUEL TANK AND IS THERE A SITE THAT SALES THE METAL PROPS FOR THE NITRO HAMMER OR DO I JUST FIND ONE SOMEWHERE THAT WILL WORK?????
THANKS IN ADVANCE
