I agree with Kyle…somewhere along the way this whole vibe changed. It stopped being about having a ball…and more about one upsmanship…the planes got heavier and bigger engines…and more one upsmanship…I recall the first time I saw an rv-4 tip the scales over 1100lbs…loaded to the gills with radios, leather everything (Corinthian no less).
And then the nose wheels started showing up…and while I’m not intentionally knocking that move…it changed again…the vibe. The feel and texture of the RV and the crowd.
Sounds like Van's, bigger better. I flew many day VFR RV-3's and RV-4's in the early 90's, with O320, wood prop, basic day VFR, or may be night lights (3 Nav and a single white strobe on the top of vertical). RV-6 came along, but still was designed around the O-320's and wood prop or fixed metal prop, simple panel, interior. I flew the Blue prototype with Richard Van off his grass strip, O-320, wood prop, very basic panel. It was and a blast and bought the kit. Than RV-6A came along.
Many builders started installing in O/IO-360 180HP and Constant Speed props in their RV-6, some shoehorned in a 200HP Angle valve into their RV-6. They got heavy, and useful load was down and aerobatic weight two up was not practical (if you followed Van's limitations). Even more atrocious IMHO were the Automotive engines, even heavier.
Then came the awesome RV-8/A and RV-7/A both designed with IO=360 200HP, Constant Speed prop in mind. Then in no particular order RV-10, RV-14, RV-9. RV-12, RV-15.... You have to have 200HP-230HP, $40K Garmin Panel with IFR GPS and two axis autopilot, $25K paint job, leather interior, on and on. A turn key RV-12iS is $190K to $225K.
THERE'S NOTHING BETTER than an a RV-4 built light, simple, handling a delight, pure fun. No need to BOOT up the glass with steam gauges. Heavy RV's are not the delight these early light RV's were to fly in pure feel. Back then builders sourced used engines and bought Wood Prop shops dozen shops: Catto, Prince, Edward Sterba, Bernie Warnke, Culver and many many more. In the North West we had local prop manufactures, hand crafted by individuals. When the principle passed away so did their propellers. They were works of arts and sophisticated leading edge treatments (rain erosion). Very light and talk about low vibration... Light weight low vibrations. As far as used engines Van's prices on Lycoming's were a bargain and that was the hot ticket. Well cost of engines now are now...
Sonex in 2024 rolled out a new high wing design. I really liked the the looks of it, like a Wittman Tailwind.
Sonex had a tragic 2015 accident with loss of CEO Jeremy Monnett, son of Sonex founder John Monnett. Also lost was mechanic Mike Clark in that accident. I thought that might have been the end of Sonex, but they carried on. Founder John Monnett, retired in 2018. Sonex employee and general manager, Mark Schaible, purchased the assets of Sonex in 2022. They had a good run over almost 30 yrs, some interesting designs, motor glider, SubSonex Jet and aforementioned high wing... I am sorry to hear this news.
I understand the call of more power, constant speed prop and fancy panels with autopilots, which have real advantages. Glass cockpits (VFR) can be had for $12,000. I know, I did it with Grand Rapids Technologies, with two axis autopilot, ADS-B In/Out, full Engine Indication System. I decided to go IFR, added a Garmin, GPS175, which added $6K. For IFR redundancy I added a G5, with independent AHRS and display. I bought a used G5 with all the goodies for $2000 a steal. I added $8000 to go from Deluxe VFR Glass to IFR. Will I fly IFR? Yes. Will I fly it enough to justify $8000? May be, may be not. I really enjoy IFR and teach students as a CFII at a flight club in my retirement. Student just passed his Instrument Pilot Airplane check ride. Nice option to have IFR capability when traveling.
