Default 2-200 lb guys in a 6

Is it common for a RV6 to haul 2-200 lb guys and full fuel?

No problem. RV-6A 0-320 fixed pitch prop. I had a 275 pound passenger, I'm 200, and full fuel for a test flight lasting 15 mins. Take off roll was 400 feet farther down the runway, I kept the speed up by 10MPH in the pattern over my normal numbers just for safety.

Dan's weight and balance database at http://www.rvproject.com/wab/wab.jsp...craftModelId=3 will give you an idea.
Your numbers will give about 1700lbs take-off weight for an average 1070lb empty.
Van recommends 1600lb for the RV-6 or 1650lb for the 6a.

I've no doubt that it would fly OK, but a -7 or -8 would do it without you being a test pilot and with more sensible margins.

It shouldn't be a problem.

Heck, I'm up to 225 and gave a 280 lb guy a ride in my 135 HP RV-9 with no problem.

Default High GW? Aft CG?

Beyond Van's recommended GW, the aft CG limit is what you watch next. You can plug the numbers into a handheld Garmin, and arrive at OW CG before/after flight. Note CG moves aft as fuel qty decreases. If the airplane in question has not, no kidding, been actually weighed, EW and EW CG determined, you'd want to do that..... An RV6 at high gross weight for landing is a different animal with the resultant far aft CG. Be careful. Also, bear in kind that G envelope compresses above 1400 lbs OW. Last, aft CG = bad for spin recovery. Approx 500 RV6 landings here if anyone must know.

Default RV-6

I have hauled 2 200lb guys and full fuel plus 100lb baggaged in my RV-6. The 6 is stronger than the 7 as far as the wings are concerned. I would watch the CG as was stated before, as you burn fuel, CG moves aft. I had to put the big battery back in just for this reason. Just make sure you do not stress the plane and land a little faster than normal to counter the weight. Just because Van's raised the weight on the RV-7 does not mean the RV-6 won't take it. The RV-6 is a much stronger airplane.

I'm the reverse. I have the heavier starter motor, and put my ELT far aft in the tailcone, and oxygen tank behind the seats to offset too much forward weight.

And of course the RV-6 is stronger! Keep saying that............ and bring up the "sale prices" of this wonderful aircraft!

I'm not picking a fight with Aden...just wanting to tell everyone else reading his post to not just take his word for it (or anyone else in this forum for that matter) unless he can provide data from an engineering analysis or static testing that can prove it.

I believe this sort of blanket statement is dangerous in a public forum such as this.

The only facts as we know them is that the RV-7(A) has an approved aerobatic gross weight of 1550 lbs (if I remember right) and the RV-6(A) has an approved aerobatic gross weight of 1375 (also if I remember right). This implys that the RV-7 wing is designed for a higher load than the RV-6 wing.
Both of the wings were statically load tested to verify wing strength at these weights. Saying anything more is (in my opinion) purely speculation.

By the way I currently fly an RV-6A so I am not trying to imply that a 7 or 6 is better or worse, only that there is no data to support a statement that the RV-6 wing is stronger than the RV-7.

The wing spar cross section of the -6 is thicker than the -7, measured at the outboard spar attach bolts. Whether or not that is the weak link I don't know.

Default Routinely fly 2 X 200!

I routineley fly my -6 with 2 X 200+#. I weigh aprox 210#s going to fly and just yesterday flew a friend to Amarillo and back who is about the same. Biggest load yet was myself and my Dad bringing us to almost 500#s in pax. No problems ever noted. These flights are generally straight and level. My -6has an IO-360 with CS composite prop, battery in the back.

Tailwinds!
