Vince,

Engine weight alone, including the plug, prop washer and nut, plus the 2 5mm header bolts, is 32.2 ozs. The ignition sensor is factory mounted. Engine typically comes with a stock rear mounted muffler and I don't have that weight.

Stand offs weigh about 1.0 to 1.6 oz depending on length. Ignition is 3.6 ozs. The engine ignition will need a 3.5 to 6.0 V source plus a switch, or other means of power supply

Compares reasonably to the Webra 145 AR which comes in at 28.8 ozs, ready for header.

Compares reasonably to the OS160, which comes in at 32.9 ozs. I guess I never weighed the stock muffler and adapter for the 160 before....a wopping 12 ozs for those who are interested. Pipes and headers beat that weight by a wide margin.

Flying report will have to wait a bit. Ed has a test bed he can use but I don't have anything ready yet. If Ed gets his in the air before the snow flies, I'm sure you will read it in the KFactor

regards

Matt
