Reverse on a SuperVee 27

[Chuckster]

Hi All, I am a noob here.. Just inherited this boat and love it.. However, the lack of reverse makes it a pain in the arse. I realize there is no steering in reverse.. and you can possible swamp the boat. however, if used judiciously, it can make it easier than walking completely around a pond just rearrange it. Sometimes I can see I am not going to make the turn and let off.. Then it stops close to the shore and I dont have enough room to get out going forward.. While practicing all I would need is to back it up straight slowly a few feet and I could get the boat going again..

Soooo, now that I explained why I would like a reverse.. How can I make/mod the ESC to actually get a slow reverse? I will take all the responsibility

Edit.. I was watching a youtube video and saw a Supervee 27 USING Reverse.. Watch this video and at 2:30 sec mark you can clearly see this boat reverse and pull back from the shoreline...
