I'm not trying to cast any shade on the work done by SWS as each RV-8 is a custom aircraft (built by a different person, using different tools and a different shop). Also, I did not do a "rivet count". Overall, the model looks great and I bought it last evening.
The few things I noticed are: (1) tail wheel tapered, tubular spring is slightly curved (all that I have seen are straight and that is the way it ships from Vans Aircraft), (2) Tie down ring on bottom of empennage (never seen one on an RV-8 and I just tie the tail wheel), (3) Sheet metal lines around / near front of canopy and cowling appear unrealistic (e.g., in the RV-8 plans the baggage door in front of the canopy is a curved rectangle, each corner 90 degrees, and that is not what is shown on the model). (RV-8s have a removal tie down ring under each wing, so the tie down rings do not interfere with aerodynamics of the plane.)
In my RV-8, I use MPH, some others us KTS, so my max flap speed is 100. I think, but did not confirm, the model uses KTS as the white line on the speed tape starts around 96 KTS. I flew several circuits around KLVN last evening and "felt" like the model required more power than I normally use in the pattern (maybe due to the extra tie down ring (lol)). In the pattern I need to reduce power to 1100 rpm to slow down to less than 100 mph, deploy flaps and add power to about 1700 rpm (granted, I have a fixed pitch prop, but should not be significantly different). I rarely have to go above 2000 rpm on final (unless I really screwed the pooch or there is a strong wind down the runway).
I have not done any aerobatics yet, so no opinion on how the aircraft handles in that regime. With a few tweaks, this aircraft will be great.
Edit: I was flying the GX3 equipped aircraft. Looking at photos of the steam gauge equipped aircraft I see that the airspeed white arch is also not representative of real aircraft speeds.
