OK Barry i copied your review and changed the results to be for the showtime, results are IMO

I also instead of going grade system i went with a 1-10 scale for results

Showtime
Hitec 645MGs all the way around except throttle HS 425bb
KOKAM 1500 LiPo on 6V regulator
all stock hardware except tank is 16 dubro
YS-110 on Header with flex pipe
APC 17x4W

KE= 10- I don't think there is any improvement for the KE capabilities of this plane, simply perfect KE at all angles.
Harrier= 7- this plane harriers,but not as great as some planes i have owned-gave it a 7 due to the wing rock I'm experiencing,maybe with a little more tweaking i cant figure it out since some report no wing rock.
Rolling Circles= 9- this plane does excellent rolling circles.but can get very fast and out of hand if not on your toes..
Waterfalls= 8-not quite completely axial on CG but it does them- also very easy to make it turn into a KE spin if wrong rudder input is applied but not bad once used to the way plane tries to fall.
Staircases= N/A haven't tried them
Rolling Harriers= 8- does them real nice and at a nice AOA- it is the only plane i own that I have to switch to low rates for them because it will do them at blinding rate on high and then they become sloppy and impossible for me to keep it at a high alpha- at low rate they are almost as good as the F90,IMO the F90 does them the best of almost any plane Ive flow.
Hover= 9- plenty of rudder authority.also will tork roll fast as you want
Flat Spin =8- I only rated it at an 8 because of the difficulty entering them. after that they are nice and flat and gracefully slow
Flat Spin (upright)= 8- almost the exact same result as inverted.
Durability= 6- my plane had lots of glue joints not glued in the fuse,my canopy tabs one has come loose, my fiberglass wing tube sleeve in the fuse came out with the tube and had to be epoxied back,one of my SFG plugs broke taking it out. i had to CA back together, tailwheel spring in stock location breaks.
Build Quality= 7- alot better than previous h9 planes,if they just wouldn't be so stingy on glue and quit using the brittle white looking glue.
Precision= 10- this plane is very precision and will let you know your skill level (and lack of it) it goes where guided and slips on the thumbs will show exactly in the air.

Overall= 9- overall i thing this is one of the best planes to come out lately.the 9 rating is just because i could say 10 but i don't think any plane is perfect.there is always room for more

these are my Opinions based being as harsh on judgment as i can on a plane i love so well.
