Today, we performed weighing of my new -7.
As I expected, it came out on the heavy side.
Here's the base:
Basically built acc to the manual, except for dual heatmuffs and a defroster-system.
Lyc IO-360, 8,5 compression
Dual P-mags
WW 200RV prop
Single landing light
Vans RV-7 light system incl Whelen strobes
Elec trim
Manual rudder trim
Rudder pedal extensions
Full interior incl full floor math set, by Classic Aero Designs
Smoke-system by Smoking Airplanes
VFR panel, incl dual AFS EFIS: 4500 + 3400.
First ZFW with empty smoke-oil tank:
LMLG: 246.5 kg
RMLG: 247.0 kg
TW: 38.5 kg
Total 532.0 kg
Then ZFW with full smoke-tank (13,2 litres)
LMLG: 253.0 kg
RMLG: 250.0 kg
TW: 42.0 kg
Total 545 kg
Note: the plane is built with the R/H seat as pilot seat, thus the smoketank is placed behind the left seat.
Just for fun, I also noted the weights BEFORE we added all the removable parts: hatches, covers, panels, seats, interiors, wheelpants, fairings, spinner etc. (in other words all the things which are removed during annual)
LMLG: 222.5 kg
RMLG: 222.5 kg
TW: 34.5 kg
Total 479.5 kg
Quite a difference....
It came out about 21 kgs heavier than my first -7 and that makes sense: my first -7 does not have the full floor math set, nor the smoke-system.
I haven't done the math to figure out the CG yet, that's tomorrows task.
For now, just by looking at the figures, it looks like the CG will be within limits at ZFW. Then we'll see how the CG goes with different load-configurations.
