I've been doing a little searching for W & B numbers but things get a little scattered. so was wondering has an ideas how much my my -7 should weigh? My goal 4 yrs ago was 1075# but now think it will be heavier than that.

Painted RV-7 w/ pants and fairings, IO-360, WW200RV prop w/2.25 spacer, James long cowl, plenum, seats and front carpet, light duty panel. ELT and Strobe pak behind Pax seat. oversize main tires(+5#)

What numbers should I expect to see?

My guess for your airplane with paint is 1100 +/- 20. My buddy's 7 is 1171 with your exact configuration, a little heavier panel with more steam in it.

I shouldn't say exact...Van's cowl, and standard tires.

My RV-8 came in at 1092 empty, primed but not painted, less wheel pants.
I figure it will end up around 1,125 once painted and panted.

Neil and I were discussing it yesterday and 1100# is my new hopeful number, but could easily be 1130.

Brian,


Just as a data point, mine came in at 1074 lbs, without leg fairings, gear fairings or paint. I have the 200RV prop in my configuration.

BTW I was shooting for 1075-1080#. But hadn't figured on big tires, special paint job, etc. I'll post the numbers later tonight. :)

It's a weird optical illusion when the TD's are being weighed...the canopy deck is level, but the airplane looks nose low.

I'm gonna go 1119, just inside my original range that I guessed. 8)

Okay... I'll bite...

Since the last couple of estimates seem to be going up, I'll top that and guess 1125.

What's the prize for the winner??? :mrgreen: :mrgreen:

Ok, ok, I'll tell you. And the winner is.......none of us, but I am the winner because it came in better than I thought it was going to. (the paint had me scared) Chad originally picked 1100, i think, but he feared the heavy looking paint also.

Certified aviation scales.

right main 511# at 68.5"
left main 514# at 68.6"
tail wheel 70#

Total 1095# @ 80.2"c.g. :yay:

I worked hard to keep the weight down and forward.

Thanx for the info on the illusion Chad.

As for the weight, I am highly impressed. I would have thought well over 1100, but that would be emotional and baseless. Good for you!
