Thank you for viewing! This product is a 60A brushless ESC from GOOLRC! I purchased it about a year ago and only used it for about a month. I drove it quite a bit on gravel roads and through puddles, but there were no problems thanks to its waterproof performance. The switch part is rusty, but there are no issues. I used it with a TT-02 and it worked fine! The power plug is a T-type. It does not support 3-cell batteries. Thank you. Please check my profile! Type...Radio Control Car
