OK, I'm guilty of posting over on E-Zone and forgetting about this thread. My Tsunami is almost ready to fly. Just need to make and install the pushrods. All up weight, with battery ready to fly, is 3.75lbs. Yup, beat the 4lb mark by 4oz. With my power system, that works out to 173W/lb. If you don't speak electrons, that means unlimited vertical approaching rocket ship performance. Should be a blast to fly. I've attached a photo of my original Tsunami with Webra .40 and tuned pipe circa 1997 (with my daughter), and also the same daughter 12 years later with the new Tsunami (or should that be Tsunam-E?)
