Review by Eric Miller
I got this to put into my Parkzone P-51D Mustang BL with 1100kv motor. It works very well. It does get warm, but I can run battery after battery back to back pretty hard through it without over heating. I had originally gotten a 30amp, but it was getting a little too warm for me to be comfortable. This 40amp is sufficient to run it matched with a 10x8 master airscrew prop. Good job Graysonhobby! Great product, zero issues with it. (Posted on 7/26/2013)
