Hi, I have noticed all over the internet that no one in any forum, mentions that the Caldera 10e 35A hobbywing EZrun ESC AND MOTOR are WATERPROOF in fact, some forums people actually say they are NOT. However, if you look at your manual that came with the Caldera (just got mine a month ago) -Not the truck manual but the ESC manual that tells you how to program your esc without a prgram card. On the FRONT, FIRST paragraph, about the quality and guarantee of the ESC and MOTOR has a numbered (1-10) list and number 9 says WATERPROOF and DUSTPROOF. not resistant and not splash. you can throw your ESC/MOTOR in a swimming pool for a month, pull it out and use it. Straight up. Lifetime warranty too. Your receiver on the other hand is only splashproof and dustproof, the so called sealed bearings are a joke, as after running hard through some deep mud puddles, I hosed off my truck as usual (REMOVE BATTERY FIRST) and the next evening when I went to run my truck the wheels would not move. I took all the bearings out and soaked them in PB Blaster in order to free them up. I then went on ebay and ordered RUBBER SEALED bearings for the truck. sooooo.......New receiver, and new bearings = WATERPROOF truck. Yes this is the Caldera 10e. Just thought I'd lend some information. Everyone pull out your manuals and see for yourselves.
You have to be careful as to what you read there.
A Redcat tech told me NONE of their esc's are waterproof. Splashproof maybe, but I would never try submersing the ESC or motor.
Problem with those manuals is that they cover many of the versions of ESCs, but not specifically the ones Redcat uses.
Many have noted that the redcat ezrun ESC's don't have the full range of programmable functions as listed in the manuals. This is because they are a lower cost version of the same esc listed in the manual.
I am not saying that the manual isn't correct, it is POSSIBLE that they are waterproof. But I wouldn't try it. And honestly, just looking at the construction I highly doubt that they are. Ive pulled apart some waterproof ESC's and it is clear that they coat the board in apoxy to waterproof. I don't see any of that in the caldera or epx pro ezrun ESC's.
Also, I can say 1st hand that the receiver is not at all "spashproof". They are in fact very easy to damage with just a couple small drops of water. The board is visible threw the plug ports. Only takes a drop of water there to short out the receiver. Sometimes you get lucky and once it dries out it will be fine, but that will only work a couple of times before the board shorts out completely.
and on bearings, no bearing is waterproof. some are better and will last longer, but even the best bearings (often found in boats) require greasing and WD40 or other rust preventatives to keep them working properly.
Short of it is, no rc is waterproof and running in any amount of water takes extra care and work. But it sure can be a lot of fun!
