Sling tsi can easily carry four normal sized adults. Swap the lipo battery for a lead acid. It really helps move the cg forward enough for four adults. The sling cabin is smaller. But the interior comes with the plane and its fancy. and for the slightly smaller width, you get 7.5gph at full speed.

Four child sized adults...

So tell us what scares you ....

Being a bad/poor builder.

So don't make it complicated. You have three choices.

Order a tail kit, and find out if your fear has a basis.

Buy a finished airplane.

Forget about it.

I agree with Dan. The tail kit is not a big investment, and you'll find out quickly whether you can or can't (most likely can - it's not rocket surgery). There are many aftermarket companies that support the RV-10 with full interiors, consoles, panel builds, etc. You'll have to make choices, but hey, you get to make choices!

Full Disclosure: Building a plane (any plane) is a significant time & money-consuming commitment, and it's not for everyone. The hours quoted by kit manufacturers, IMHO, are for the airframe, not the whole enchilada, and the total doesn't include all the time you'll spend reading, learning, researching, polling (like your thread here) and generally head-scratching. You will be eating an elephant, make no mistake about it.

That being said, if you complete the journey, you will be a member of a small brotherhood, to be sure. No one can possibly understand what it takes, unless they've done it themselves. If any of this scares you, you should buy a flying RV-10.
