You don't seem to understand my point... The company shouldn't warranty anything. You received a working model, the manufacturing company did their job. You took that working model and blasted it through water. You should have sence enough to know that electronics and water don't mix. I bet you wouldn't take your cell phone and toss it in the loo, even if it said it was waterproof, now would you?
So for them to replace your vehicle for free, it isn't really free... That cost gets put on the rest of the models and parts. So the next buyer is paying for your freebie that you destroyed and English law saved you the cost of a new model.
My point, if they made 100 models and could sell them for 100 each and make a small profit. (These are all small numbers to make the math simple for everyone)
25 of those models come back to be replaced free of charge, the company doesn't eat the loss, they raise the price on following models to recoup that loss. So now they have to charge 125 for the same vehicle, but now there is 25 extra to cover the loss and still maintain a profit. Another 10 come back for free replacement and the price goes up again... The price of the model and the replacement parts keeps going up until it becomes unaffordable to most buyers, like the 5b/t, or the company goes out of business because they can't recoup the losses from having to replace models.
If you buy a new car (1:1) and drive too fast into a puddle, the car hydroplanes across the water and total out your car, you don't go back to the dealership where you bought it and demand a replacement because of your mistake... They would laugh in your face!
If you buy a RTR it is your responsibility to go over the model and electronics carefully. If the motor starts and the servos work when you buy it, the manufactures job is done. What you do with it from there is your responsibility.
I had a similar problem with several Hitec servos, $600 worth. When they get wet they die. Yes, I too sent them in for repair, but the cost to repair was greater than the replacement cost. Did they warranty them? Hell no. Did I buy any more from them? Hell no. They too have a "Water resistant" slogan on the box... I didn't expect them to warranty them anyhow.
So your free replacement is going to cost the next guy in line. Which is one more reason why this hobby is so bloody expensive.
Common sense goes along way, I don't care what English law has to say, it was your fault, you should incur the cost of replacement.
