I recently decide to build another small tricopter and wanted to use a small but good ESC. I am very pleased with this ESC. It is very low in price but works just as good as the more expensive ones I have used over the years. The size is very small so it is easy to build into the inside of a tricopter frame with no problems. It was also nice to be able to add the motor wires to get a more accurate length for my application. Value Hobby comes thru again with price and value!!
