Kelly,

That's a tough one. The 3-rotor weight typically quoted is 295#, but this isn't fwf. Take into accou= nt that I am running dual alternators, an aluminum Renesis water pump housing a= nd aluminum water pump, p-port intake, and it is difficult to say the fwf weigh= t. What I can say is that my a/c weighed in at 2050#, which is very close to th= e typical Lycoming Lancair. Going by that, I would guess that my fwf 20b weighs close t= o what a fwf IO-540 weighs.

Going at it from a different angle, I believe the W&B showed about 550# on the nose gear. T= hat would be a pretty good ballpark number for FWF. Its been a while, so I would= have to check the logs to see exactly what the weights were when first inspected.

Can you give me a wire wall forward weight of your 20B= minus the oil & water radiators

and your constant speed prop or your best estimate ??.= ..........
