RE: Tower Pro bmc25a esc
Tower Pro is know for not providing instructions for their ESCs and even then they are usually the wrong instructions. In addition, several versions of each ESC might be on the market with differing instructions. I went through this problem with the generation two 30 amp ESC. Please go to rcgroups.com in the power sources forum and look under a thread starting with "Coution" (Caution spelled wrong) and something about Tower Pro ESCs in the title. While this thread pertains to the 30 amp unit I bet the instructions may be the same. Either way, you'll find links to various manuals for the TP ESCs on that thread. Read the whole thread so you know what's up!
