I'm building an RV-7 and I like the concept of the RV-14. I especially like the larger cabin space and improved visibility. These are my two perceived shortcomings of the RV-7.
I also like the improved (RV-10-derived) nosewheel design (the main reason I built an RV-7 versus an RV-7A).
The "easier to build" canopy design is intriguing, as is the modular wiring design and engine baffle system. I am concerned that the new design would end up beyond my budget (especially with the angle valve engine), but that is yet to be seen.
However, while I like it, I really don't NEED the larger cabin (I'm about 165 lbs wet) and the RV-7 performance numbers appear to be better for my mission. I would appreciate the increased range.
So I'm not feeling like The RV-14 will make my RV-7 obsolete

. In fact, It may just make the future value of my RV-7 higher due to the potential of fewer total RV-7's built in lieuw of the RV-14, especially if the 180 HP medical limit is ever finalized.
Overall, I like it...
