Thanks Paul - it's been a long time, but lots else on
Probably a day's solid work to prep for flight, but no spare diary time for some days.
Most RV-3's are around 800 lbs, where did you save the most? Did you use primer?
Yes - all interior primed with Zinc Chromate Etch. I have a list of where I think the savings were made, using a few (2 in particular) well documented RV-3 builds on here. There is no single item that "saves a lot", it is just thinking weight at every point / decision. The panel above shows the idea - the easiest way to save weight is not to put something in at all.
Easiest tip is avoid avionics that start with a G
Whilst high quality, they are heavy, and that's not just on the wallet.
It still needs a VHF & Xpdr, albeit Dittel VHF arrives next day or 2 (360g, 0.75lb), and I'll take bets on how much the blue film weighs (the canopy plastic and masking tape was >8oz).
I used blocks of Minicel foam to do the seat - quite easy, and <2lbs for both 'cushions'.
Engine is narrow deck, small (SD-8) Alternator, Sky Dynamics sump / exhaust / intake / flywheel, XLT starter, no relays.
It would not be right to compare it directly to specific other RV-3s - some on here are full IFR cruising aircraft, with comforts and redundancy I will not have.
More photos as I get time, hopefully a flying video before too long
