Default Question on RV-6A Useful Load

I am new to the site and forums and enjoying the heck out of all the good information.

I am looking to buy a RV-6A with a iO-360 and FP prop and noticed it's Empty Weight is 1,168.40 pounds and of course, Gross Weight at the factory listed 1650 pounds. This leaves only 481 pounds Useful Load. At 38 gallons fuel capacity that leaves about 253 pounds for the wife and me. With these numbers I would need to get a new wife or drop fuel.

What is a typical Empty Weight for an RV-6A?

Is the stated Empty Weight of 1168.4 a concern?

Empty weight of 1168.4 lbs. would be a concern to me. My RV-6 is fully equipped at 1040 lbs. with a 3-blade Catto prop and extended range fuel tanks.
People today don't seem to be concerned with empty weight. A light RV flies Sooo much better than a heavy one.

My -7A came in at just over 1100 when built with a PC-680 battery on the firewall and 3 blade Catto + 20 lb Saber crush plate (for CG) on an O360-A4M that was upgraded to AFP fuel injection and dual P-Mags. I have since dropped 11.5 lbs by replacing the PC-680 with an EarthX ETX680C. Should be around 1095 lbs empty, now. Not yet painted.

Is your engine an angle valve (not likely with the FP prop)? If not, I suggest having the plane re-weighed.

an angle-valve IO-360 would certainly add some weight. My 6A is a little heavier than I would like at 1088, but that includes a 20# crushplate to improve the CG. I could drop a good 25# with a lightweight starter and aluminum crushplate, but it would hurt my CG too much. I could also improve my weight and CG by switching to the smaller, much lighter, original RV-6 vertical stab and rudder. I have a RV-7 tail.

The 6A is always going to come in a little heavier than the 6 since it has the extra gear leg plus all the extra weight required to shift the main gear aft. Van's lists the empty weight at 985 vs 965 for the tailwheel model. I don't know how anyone would hit that number with paint, but it can apparently be done. I think less than 1100 is acceptable for a painted plane - but just my opinion.

My RV6-A with paint is around 1040, o320 d1a, and sterba prop. My POH states 1800lbs max weight , I suppose the builder tested it at that? I keep it at 1650 though as I believe vans more

Van's builds their planes, the early ones at least, as simple VFR ships.
No interior, minimal panels, manual flaps, O-320, (wood?) fixed pitched props, etc.

Everyone seems to want a minu-Airbus and loads their airplanes up with ever imaginable option these days.

It is easy to build lightness in, you just have to want the trade-offs.

When people ask my advice about buying an RV, I tell them to look at the empty weight first.

My airplane (RV-6, O-320 wood prop) weighs 1030 lbs. If I swapped to a Lithium battery, that would save 10 pounds. I could remove the 10 lb flywheel weight. I have at least 10 pounds of carpet and "extra" upholstry in the airplane and 5 pounds of ballast in the wheel pants (once upon a time, it was thought that helped prevent shimmy). Strip off 20 pounds of primer and thick paint and reconfigure to a tip-up (that saves 5 pounds, IIRC). Remove all of that excess weight (and throw the autopilot out too) and my airplane is headed towards Van's published weight.

If you had seen "Old Blue", you'd recognize it as a VERY bare bones airplane, including near-translucent paint. You don't see many like that.

Default My 6A

My 6a is 1096 per last W&B O320 fixed pitch wood Warnke prop. Seat cushions is all the upholstery I have, no brakes right side. Your weight seems a bit heavy, but no info on panel, interiors, prop. You could get to that weight . I would not mention weight to your bride 😉

My -6, 0320, rv200 c/s prop, dual efis, autopilot, ifr, flightline interior, earth x battery, lightweight starter and alternator, base/clear heavy paint plane weighs 1105lbs with a 1750lbs gross weight. The problem is more aft cg than total weight. I can carry a passenger or bags, but not both. I have a 10lb weight hanging on the alternator to help with the aft cg.

Default Our RV-6

Lola, our RV-6 tilt-up weighs 1040 with a full gyro panel, KX-170B navcom, KN-97 Transponder, DME, fixed wood prop on a light, simple carbureted O-320. Hoping to replace the gyros and vacuum pump with a G5 soon. Saves at least 10 lbs? An 1100+ lb RV-6 sounds kind of heavy, even with the nosegear. When was it weighed last?
