Ken McNeill is no longer Blue Moon Kites and the Mamba is now the M3 - and I've bought one.
It's the first full-size kite I've had since I stopped competing about 20 years ago. I'd forgotten that means bigger arm movements. I've not had the chance to fly it much yet but it tracks beautifully and speed control is amazing. The build quality is amazing, as you'd expect from Ken. The kite came with three small brass weights to add to the tail. I tried it without any but found it too hard to do any pitch tricks. I then put on all three, but that was too much. I've settled on just one, but I've only flown it once since then in a very iffy wind, so the jury's out, but I expect I'll settle on one or two. I'll add some more here when I've had the chance to fly it some more.
