I'm very new to this. What kind of ESC to get?

Ok, so I bought my son a RTR Electrix Circuit 1/10 Stadium Truck. The thing is a whole lot of fun and it's the first hobby RC that either of us have used.

We had it out yesterday on the street in front of the house. It was going great, but then we drove it into a snow bank. It kept running just fine, but after a while it lost its ability to go backwards.

So I took it apart and please bear with me while I learn all the parts. This part --> http://www.ecxrc.com/Products/Defaul...ProdID=ECX1070 the green light stays on when I turn it off, and when I turn it on the red light flashes on and off while the car tries to move by itself. Not to mention that it won't go backwards. Is the part I listed in the link the only part I should get for it, or can I get a more waterproof unit so this doesn't happen again. I saw this one on the parts list for this car on the company site too. --> http://www.ecxrc.com/Products/Defaul...odID=DYN4925WP Will that be better than the stock one?

Can someone also point out to me a good site that gives me individual part listings and what they do? I'm totally new to RC cars so I want to learn and so does my son. Thanks!

First I would contact Horizon Hobby and see what they say. They may send you a new ESC. I looked through the manual and I don't see where you can calibrate the radio-HH should help with that. I've been using Traxxas XL-5 ESC's on my brushed trucks (winter beaters) and they have been packed with snow numerous times. I just dry them off with an air compressor and I haven't had one fail yet. Head over the forums at URC (UltimateRC.com). That site is more for cars and trucks. Let us know if Horizon helps you out.

I would say if you went into a snow bank the ESC(electronic speed control) is cooked. If you are going to drive in the snow I would recommend a "waterproof" ESC. They are more water resistant then proof. Contact Horizon they may send you a new one. If not take the old one and stick it in a bowl full of uncooked rice for a few day's it may be wet and need some drying out. The rice will help dry out the moister.

ECX claims the ESC is waterproof, and I don't think getting snow on it would cause it to fail. My Axial Ridgecrest says the ESC is water resistant, so I only drive that one in dry conditions. But I have had my Traxxas trucks completely packed with snow (XL-5 and VXL ESC's) and they haven't failed yet.

Because the light stays on when it's turned off there may be water in the switch. it will probably dry out on it's own if that's the case. If the green light only stays on a few seconds after the switch is turned off it's not a water issue, just normal operation for some ESCs. Their internal capacitors can hold a brief charge sometimes.

The red blinking light indicates an error most likely. Was your radio on? Always turn it on first. If there are any radio setup instructions shipped with your truck follow those again. If you want a better ESC you can spend as much as you want

I went to the exrc website and looked up the ESC instructions: http://www.ecxrc.com/ProdInfo/Files/...Prog_Guide.pdf. There are two conditions that cause a blinking red light, low battery and ESC overheat. A low battery can cause all sorts of weird issues, too.
