Default Get an 8

I'm 6'2" and 285 lbs. Get an 8 you will be fine. You can even get the tall boy package where you can move the seat back a little more.

Have you ruled out the -14? It has the room you need for a premium that isn't much over the -7 when completed.

I looked at the 14, and would love it I'm sure, but my dad and I already have experience building the 7A, and I want to stick with the O-360. From what I've read from owners or pilots who have flown both, they RV-7's are more nimble, faster and burn less fuel and cost less to build. If I had about $30k bigger budget, I'd build a 14 to outperform my 7A vision. The 14 would definitely be more comfortable and haul more baggage, but the price and cost of ownership make it slightly out of reach.

My dad really likes the RV-10, but I want the aerobatic capabilities. For hauling family, and teaching, my dad loves his slow but rock solid & stable Cessna 172.

The cost of a plane, car, tool, or anything is the difference between what you pay for it and what you can sell it for. Cost to operate needs to be considered and the 14 will cost more per hour to fly but the resale value of the 14 is very high. People are willing to pay for comfort.

You know the 7 so If I were you I would find someone with the Antisplat mod and sit in it - then decide.

Chad,

I honestly think you would be nuts to build an RV-7, and that's coming from an RV-7 builder/driver.
Let's do some simple math. You say you want to use the aircraft for aerobatics. The RV-7 has an aerobatic useful load of 486lbs. After you (240lb), a 15lb parachute and 18 gal (108lbs) of fuel, you've left with 123lbs for passenger and parachute. I'm assuming most of your buddies don't weight in at this level.

The RV-14 on the other hand has a 660lb aerobatic useful load. Assuming you carry 10% more fuel, this leaves you with 286lbs for passenger and parachute.

On the $ side of things, I think you are totally over thinking the cost delta. The difference between engine prices is about $5k (IO-360M1B v's IO-390) The running cost LOP will be a negligible difference per year (maybe $140/year assuming a 10% increase in fuel flow and 50hrs per year) and the build cost difference is also negligible, keeping in mind that the build time of a standard RV-14 is about as fast as the quick build RV-7. You will easily spend a couple of years longer building a 7 than a 14 and are you factoring this into your equation. You say your father wants you build a 7 because that's what he's built before, but who's plane will it be in the end?
Ultimately I see the 14 being $5k more expensive for the same build speed, but you will more than make up for this on the resale side. You need to factor in what that 1000hrs in build time saving is really worth, not just in your time, but also shop space, lost weekends etc. The only thing I would maybe look at is getting a 8.5:1 compression ration IO-390 so you can run mogas.
If I learnt anything during my build, that is don't build something you don't want. Do it right the first time. If you build a -7, you'll regret it every time you hop into it with any reasonably sized individual, especially given that you know you can't legally go and do aerobatics, and if you do, the thoughts that the wings may go flap-flap will be burning like acid in the back of your mind. I'm 170lbs and the 7 fits me fine, but I know if I was 240lb what I'd be choosing if there really was only a $5k cost difference. You build a 7 with all the big boy mods and selling it will not be as easy as a normal 7, as this cuts into the baggage space and there will be the thought in the mind of potential buyers that the aircraft possibly operated in an overloaded condition due to the higher than designed passenger weights.
My 02c.
Good luck.
Tom.

The 14 is sweet, as is the RV-10, but I pulled the trigger on a deal I couldn't pass up. My dad and I ended up buying an RV-8 kit to finish as a father son project. I found a partially complete kit (1,000+ hours in the build log) that was available now and got it for a good price. I sat in the canopy and I fit with just a couple minor fixable issues on comfort. The bottom of the instrument panel was close to my knees, but there's room to trim off another 3/4. The lower vent will also be relocated as it was a bit in the way of my right leg. I feel like I fit better in this than I did in my Dad's RV-7A, so I'm very happy with it. I'm extremely happy that I don't have a 14 month wait for a kit. We might have this plane flying by the end of the year

I'll be on this site quite a bit looking at all the great ideas.

I should have clarified that I do not want to do aerobatics as a hobby or as my primary flying enjoyment, and definitely not in competitions or shows. I simply want to learn do chandelles, aileron rolls and maybe loops. I don't plan to push the envelope too much, though hitting 3 or more G's is more "danger" than the average person is willing to attempt.
