I just finished assembling a Sig Kadet Senior and I am surprised at the finial weight. The specs say 6-6.5 lbs. but mine ended up at 8.5 lbs. Of that, 12 oz is balast in the nose and 23 oz is for a OS 61 FSR-abc engine and muffler. So without engine and balast I was already over the max spec weight of 6.5 lbs. It was a by-the-book assembly. The wing loading is still only 17 oz per sq ft., so it should fly fine.

What weight did you all end up with on a Kadet Senior?
