Just some thoughts and opinions on operating at higher gross weights, which have been discussed in a number of other threads in these forums. I have over 500 hours on the RV-10 now, under a lot of different loading scenarios. Yes, you can put 4 full sized adults in it and go fly. Do you want to max out the baggage and the fuel at the same time? I think that is a question that each individual pilot will need to answer. Will it carry the load? Yes. Under normal situations, standard temps, etc. What one needs to think about are the exceptions such as: what happens if the engine misses a beat, is the runway long enough to abort, how will the engine handle the prolonged climb in the heat, is the field smooth pavement or rough grass, how does the CG move as fuel is burned off, what about turbulence, what about the long term effects on the airframe/landing gear from operating over the recommended gross weights, along with a plethora of other questions.
And at the top of the list I would submit that the passengers are putting their faith in our judgment. Probably none of them have agreed to be test "passengers."
Please fly safely. We have a pretty good sized fleet of RV-10's out there now, and so far, so good. Let's not disrupt that track record. We will all pay.
I understand some of you who are wanting to build really want to know if it is a true 4-place airplane. As someone else mentioned regarding the C-182, which is probably one of the more honest 4-place airplanes around, and having owned a C-182 for a number of years, Ithink the RV-10 is a real 4 place airplane. But like any airplane, including the airliners, everything is a trade off---- people, fuel, baggage---- and there are limits.
