I'm still studying the RV-4 market in depth. This site is huge for information! That's a big help. So, I'm hoping to tap into the wealth of experience here.
Van's website under specifications says 905-913 lbs for an empty weight. I haven't seen many like that. Make that ANY like that.
Flip to performance, 193 mph cruise for a 160 hp, 75% power @ 8000 feet? 201 for 180 hp? Is a 200 mph cruise realistic?
"Top speed" over Vne with a wood fixed pitch prop?
Rate of climb at gross 1,650 (160 hp) - 1,950 (180 hp)? 2,050 - 2,450 solo?
Is this with the same wood FP prop as the 204-213 mph top speed?
I've read posts where the Catto added 15 mph, etc. over a different prop.
What are the real numbers, verifiable, repeatable numbers that can be honestly expected from an RV-4?
I've read and heard that Van doesn't exaggerate his numbers as other experimental manufacturers do. I'm hoping that's the case. If you guys would share your true real world numbers here with engine/prop configurations, I'd be very interested to see them and compare. I want those numbers on Van's site to be true.
Thanks --
