2 RV8 QBs
I may have the record here at RV Central
One built here in 54 days, a RV8a QB
Another built in 92 days, a RV8 QB
I built my RV6 kit,my first RV, in 18 months, by myself. I was motivated to get it finished. That was 1995/96
We have the experience to get it done IF you do not make us learn a bunch of NEW tricks. ie,,,.... The new sumps coming out have different nonexestant mounting brackets for throttle cables, just one thing that you can get hung up on. Another is the New Glass stuff have a bunch of remotes to mount. ALL this add up to a LOT of extra time, figuring it out. ,, aren't you supposed to be looking outside the cockpit? The remotes that come with this new equipment add up the hours. I have a friend that has 5 different airplanes and they all have carbs, and mags. Why? He says they are easier to work on. I have these to "fly not so I can have an extra job".
The aforementioned 'super' quick builds had the owners working up to 14 hour days with me as supervisor, Troy fiberglass, and Vroom electrical, all helping the owner. Both RVs did NOT have any thing out of the standard Vans kit, and parts. We put mags to fire the engines. Standard round circuit breakers, not square ones. We made our own panels so we did not have to wait for a water jet company to get to us. The gauges were round and we could cut the holes with a punch. We used simple paint in the interior. Both, the owners had built the empennage before coming here.
The The 92 day RV8 won Reserve Grand champion at the Casa Grande Air Show Fly in the same year. He also had the smallest labor bill in my 12 years of helping people with their RVs.
I have seen builds from out there that take too long because the owners are putting 10 pounds of stuff in a 5 lb bucket. It adds to the hours to build like you would not believe. Keep it simple and you can have a RV in a reasonable time.
Hear is the math....
RV8 QB, Carb, Night lights, Cross country VFR = 1000 hours to build.
3 hours 3 nights a week + all day Saturday,,, go to church on Sunday = a flying airplane within a year of receiving all the parts.
Easy... but you have to be motivated.
I sell my time to others because I can condense their time to build an RV. I have helped a lot of RV builders get flying sooner.
