Got it set up on the run stand and ran flawlessly. That was, until the battery ran out of juice lol. It fired on the first hit so I must have had the timing pretty close when I reassembled it! All total I had 4 recording devices. Most of the time it was just 3. One was a Panasonic hand held camcorder (the one that has a sensitive microphone that gets blown out at high noise levels), the DSLR my wife was holding, the GoPro on the car next the engine, and my Iphone 6. Damn I love the sound this lil small block produces.
