I've got about 40 flights on mine now and the Taurus is realy starting to run. The only lightening I did was the Carbon Fiber landing gear and I don't think it makes that big a differance. I have no problems pulling out of a hover even at 6200 feet above sea level. The planes fly great and the new 330 is suposed to be even lighter. If you are a kit builder, Colombo makes one of the best 50cc kits out there for the money. I think Rocco is going to offer a winter special on these also. Give him a call.
