My Echo 23.6cc weighs 34 ounces with the muffler and radial mount. A Saito 1.80 weighs 31 ounces with no muffler or mount. My CH ignition with Bosch cap and battery weighs about 7 ounces. Total flying weight is 40 ounces on my Echo and the Saito will be right there with a good mount and muffler. Run it on a mag and the Echo will weigh more, run it on gas/glow and it will weigh less than the Saito. Biggest advantage here is gas is still way cheaper than glow and will fly much longer on the same fuel load. The Echo will turn a 16/8 about 7500 here in the humidity and heat. Ahhh choices...
