So now it just beeps every few seconds and doesn't pair with the remote control. Are the engines allowed to get wet? He was throwing it around the pool. I'm guessing I have to WD40 it and let it dry out. Any and all help is appreciated since I know nothing about this. Thanks!

That sounds like either the speed control or the receiver, depending on it's drive system. You said the engine got soaked, so is this boat powered by nitro fuel, gas/oil or batteries?

LiPo battery

Okay, that makes things a little more clear. Now I have a couple more questions for you so we can narrow this down a bit more:
1) Does the rudder work when you try to turn it with the transmitter?
2) Have you tried swapping the speed controller and rudder servo connectors on the receiver?
3) Have you tried to spin the prop shaft by hand(with the batteries not installed for safety)

These questions will harrow down where we need to look next:

• If the rudder doesn't turn, that says it's a receiver issue and you will need to try to rebind the receiver to the transmitter. This should be explained in the instruction book(s) that came with the boat. If it won't rebind, you may need to replace the receiver.
• If the rudder does turn, swapping the connectors will verify both channels work in the radio system and will rule out a radio problem and will tell us it's a speed controller or motor issue.
• Question 3 is to verify the motor and bearings are still in good shape. If the shaft spins easily, resetting or replacing the speed controller should take care of the problem if the radio is working properly. If you feel drag, that means either the drive shaft needs to be greased or the motor has corrosion building up inside. Removing and greasing the drive shaft would be advisable anyway as it's part of the basic maintenance required by R/C boats. I personally use a lithium based white grease on my boat's drive shaft

For the record, this is my boat:

Here's a link to another one of my boats, this one is all wood and smaller than the orange one:

The rudder doesn't work with the controller. we also tried greasing the shaft but the shaft won't come out and even the guy at the RC shop said that it's stuck. I'll look into the other items and report back. It's a brand new boat and it's only been used in a pool very briefly.

The propeller doesn't spin at all manually.

Okay, that means the receiver got soaked. I would go through the instruction book(s) and see if there is a way to rebind the receiver to the transmitter. If not, you may have to replace it.
As far as the prop, are you saying you couldn't physically turn the prop shaft by hand or were you trying to turn it by using the controller? Just want to make sure we're on the same page on this one.

Thrusher

I couldn't turn it by hand at all. He tried to grease it himself and I'm not sure he put it back together right. I looked into rebinding in the manual and there isn't much info for it. The receiver definitely got pretty wet.

Thrusher

Found the instructions for rebinding. Will try after work.

Something that would help is pictures of the motor shaft set up and the strut at the rear of the boat. Being able to see them might help me see why the shaft won't come out

Thrusher

Ok will do

This site won't allow me to post pics until I have 10 posts. I could email them.

Hydro Junkie

Not to worry, you only need two more posts so it will be soon. Any luck rebinding the receiver?

Thrusher

I am waiting for the battery. He uses it for his car also. I'll post again and see if I can add pics.

Thrusher

Hopefully this is 10.

Ok I rebinded it and it works. I am taking it in to get lubed up since the shaft is stuck. Thank you.
