Default What is a "Light-weight" RV4?

I am currently looking at a 4 weighing in at 1020 lbs. Is that an acceptable number considering it has a O320 and wood prop?

Thanks,
D

It's not too far out of the realm of average. My O-320, wood prop, RV-4 weighed in at 968lbs last time it was weighed. I have a buddy with a -4 about the same weight as yours. Mine's 160hp and his was 150hp before overhaul, there was a performance difference. Now he's 160+ and performance is pretty equal.

Here's to hoping you're looking at a 160hp 320.

Thanks justin, itís a 150hp but I anticipate myself increasing the hp with high compression pistons. Old avionics are going to be replaced with a vfr basic glass panel and a strip/paint is def in order. So we shall see if I can lighten her up a bit in the process.

Thanks again,
D

My short legged 4, painted, glass panel, 160HP, w Sensenich GA prop weighs 965 pounds on calibrated scales.

1020 may be correct, but it is very common to have aircraft weighed on scales of dubious calibration.

For example, back in 1994 when I had no money and no calibrated scales, my same 4 weighed 940 pounds on bathroom scales... with a much heavier steam gauge panel.

So, if you want to actually know what the plane weighs, get good, calibrated scales and do it again.

When I purchased my about 6 years ago, it was 1015#.
I put it on a diet and it lost a vacuume pump, steam gauges, and "pink battery".

Now it is 935#


Hoping to shed some tailwheel weight next.


Your are fine.

That's a little porky to my mind. It only gives you 300lb to Van's max weight with full tanks. Does depend on your size and the size of your regular passenger. Are there any opportunities to lose some weight? If the airplane is otherwise good it be a negotiation point ...

Particularly with a wood prop, an RV-4 at that empty weight would be considered pretty heavy (there are wood prop RV-6s' that are that weight).

I would consider a light weight RV-4 to be one that is below about 935 lbs.

After speaking with the owner, looks as if the plane has TWO coats of paint on her. Hence the weight.

Default Bunch of LIARS!

What you will find with RV empty weight is oretty much what you will find with asking most ladies what they weigh before giving them a ride in your RV.....LIARS 😂😂😂 You would be SHOCKED to find out how many builders do their weighing BEFORE the RV is painted then never weigh it again. And before interior. Or latest mods, etc. If you really need to know the weight, get it weighed with accurate scales. In the several years I have helped airport buddies buy many RV's, 6 RV's in the last two years. Not ONE bought had an accurate weight and ALL 6 were heavier than stated. An 0-320 with a wood prop SHOULD be under 1,000 pounds but if its a nice build with full interior and old IFR panel it will weigh over 1000 usually. Maybe the seller is HONEST 😂😂😂. My big safety check is THE TAILWHEEL IS CLOSE TO 50 POUNDS. Aft CG is a killer, I'd do my own W&B calculations and find my limitations. And oh, there is probably not a single RV-4 pilot who hasn't flown over 'gross weight'. RV-4's are incredibly overbuilt stout airplanes. Only thing I would NEVER mess with is aft CG. That will kill you in an RV-4.

Enjoy your new ride Sir!
