Areas of concern
Though these boats are rather inexpensive there are some areas that you want to pay attention to so you do not lose money with this hobby.
Switches in the boats have been rusting almost immediately. Check it and change it. Do not cut the wires off of each end of the switch to replace it. Only one wire is on the switch the other just passes through it. I am going to look for a better switching system. I am thinking about using a magnetic reed switch. This will allow us to turn on/off the boats without removing the cover. You just put a magnet next to the switch to turn it either on or off, I have not figured it out yet. Or maybe just get a waterproof toggle switch to replace the one that comes with the boat.
Careful with the rudderpost
If you are keeping your boat together you will have problems with the rudderpost, which is steel. It will corrode. It can lock onto the rudder tube and take the whole thing out. It is not a problem as that is sealed from the bilge and fixable. Make sure you lube it nicely with lithium, vasoline or something else you like.
Keep water out of the radio box
Use a sponge inside under the sheet entry hole. Also check your boat periodically, while sailing, to make sure you do not have too much water inside.
Waterproof receivers and servos
Check to see that there is silicone or some other sealant on your electronic components. Here is a link to an article that is on the website to further waterproof the electronics: Waterproofing Electronics from Boat-a-Holic
I just ordered some dielectric oil so we can all drop some into the electronic equipment that we can reach. I think I got enough for anyone that would like to use it.
Check the knots on the lines
The knots on the boats are not good. Make sure you check them and retie any (most) that are suspect.
Plastic for keeping sheets clear
Cut and install a thin piece of plastic under sail arm and over all the rest of the electronic components.
Don't lose your Hatch Cover
The hatch covers are being lost. It is recommended that a retaining leash be attached to the hatches so they do not get separated from the boats.
Prevent sail servo arm slippage
the sail arm can start slipping on the motor of the servo leaving you floundering on the water. Check first with a Phillps head screwdriver and make sure the screw on the top is tight. If you still have problems you can carefully drill a small hole near, but offset, the center on the top if the servo arm to insert a small screw to act as a key to stop the slippage.
