Mark,

You posted some videos on utube a while back.  Have you made any recently?  Folks like me really like to watch them!

Kelly,

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