Here's a picture of my Nerf Defender. It is perfect for SSC. The AP engines .15 is only turning around 14k with %10 nitro and Topflight 8X4. It doesn't have unlimited vertical, but at 2 lbs has enough to be fun. Flying as slow as these planes are flying the flat bottom flies AWSOME. It is rock solid even in a slow loop. I don't believe the 2.5 lb rule is a good one. The original rules were a great starting point, but we are seeing that the disadvantages (snapping out of turns and hitting spectators, sluggish vertical performance and overall crappy flight characteristics) of an extra 8 oz far outweigh the potential good (slowing down the aircraft). We are seeing that a .15 sized airplane with 400 sq in of wing will generally come out at 2lbs and fly much better than a lead sled at 2.5 lbs. I can see a 2 lb MINIMUM because that would keep the high tech guys out of buying expensive carbon fiber and whatever else they can use to get an edge, but for people's safety and overall flight performance, 2.5 lbs should be the MAXIMUM, not the minimum. This planes wing was cut from foam insulation and uses a coroplast fuselage that bounces rather than shatters like the gutterpipe sometimes does on impact. It is reasonably light (2 lbs) and flies where you put it which is exactly what we want in a safe, fun combat airplane.
