My plane builder listed th e GW at 1650, empty is 1080, but I had seen other ones at 1750. I have been told the 6a has safely carried up to 1850, even tho GW at 1750. I once unk nowingly carried a psg who later told me he weighed 235lb, didn't look it, but landed much harder that usual. I usually carry 200 lb psr max with full fuel and min baggage. Over that I usually carry 3/4 to 1/2 fuel. as a mater of fact I have not had anyone with me over 150 lb for past 2 yea rs.. I have weighed 185 for several years. And at 75 that is not easy to do =2E BTW, knowing that Art xxxx racing in cherokee 140 used to carry his psgr in back seat, so when I did my first race I had 80 lb of batteries in bagage which gave me extra 5mph. Hope to get to bottom of this gross thing =2E Yhanks, Charlie --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ________________________________ Message 5 _____________________________________ Time: 05:31:18 PM PST US From: vanremog@aol.com Subject: Re: RV-List: 6A gross wt I established and tested for 1900 lb utility gross weight with thirty hours on the Hobbs under the following condition, because I wanted to ensure ade quate margin for cross country flights loaded up with baggage. I weighed 185 lb at the time and my 241 lb buddy was along in case he neede d to grab one of the two 50 lb bags of sand out of the baggage area and hol d it in his lap. We worked our way up to this point slowly and performed a ll of our stalls and landings. I have an O-360-A1A and constant speed prop .. The plane handled fine throughout the flight but I carried a little more sp eed on landing just in case. I'm not sure I would fly it to empty tanks th ough. An arm of 75.73 is right at 27% MAC. YMMV.

Depending on which version of operating limitations are on the plane, it could be as simple as logging a return to phase one, flying 5 hrs of tests at the increased gross weight, and logging the successful results with a return to phase two (normal operation). Newer versions require notifying the local FSDO & getting their approval for the proposed test area (which might well be the same as the original test area). Not saying anyone should; just that it can be done. As mentioned, there are lots of 6's & 6A's with higher than 1600 lb gross weights in their oplims. Tangentially related to the subject of best glide, Van once wrote an article about best climb rate in the short wing RV's. He indicated that due to increased induced drag of the low aspect ratio wing at low airspeeds, the 4/6/7/8 would climb at almost identical rates at anywhere between around 90 mph & 130 mph (rough numbers from my flaky memory). His suggestion was for normal (not obstacle clearance) climb to be at around 130 mph because the rate would be the same but a lot more ground could be covered. I've never bothered to test it, but it seems reasonable that a slightly higher speed might extend the *range* of a glide, as well.
