I just traded for an XERUN 150amp combo and it just came in today. I haven't had a chance to do much with it today yet. But I did go through the 2 in 1 program box and setup the ESC. The programing of features is nce and easy and the screen is easy to read. I have a 80 amp XERUN ESC also. I have had to mess with programing it through the transmiter which is a hassle so I was very happy to see that this program box also works with it as well. another thing that suprised me was the size of these two controllers. the 80 amp and 150amp controllers are the same size. Phyically they are identical. the only differece is one has an 80 amp sticker and the other has a 150 amp sticker. I plan on running the 150 amp in my GTP2e for speed runs with a Castle 1515 2200 motor. I may go ahead and try it with the 2250 motor it came with just to see how it does. Hopefully this ESC will handle speed runs better than the Mamba Monsters have!
