I had the factory front door off of the Shrike today to replace the rubber seals.
A good opportunity to weigh it since people often mention the weight penalty for the shrike mods.
It felt like 35 lbs while I was carrying it around, but only came in at 23lbs 6 oz. Of course the skin, stringers and window of the B models weighs something too. I’d bet with the added airframe structure around the door etc. it would cost you 20lbs too add a front door.
Along with the cosmetic gimmicks - eyebrow windows, shrike nose, “winglets” - there’s the additional weight of flush skin control surfaces with their associated mass balance, the door, some soundproofing, and probably myriad little marketing “improvements”. I note in another thread that Jim’s middle seats weight 26lbs, whereas my el cids with hydrolok recline weigh 39lbs.
Could anyone with some direct experience estimate the weight delta between a comparably equipped 60s B model, and a 70s S model?
