No flare at 60 kts....
...and full flaps. (:
Made an approach to short runway over trees and forgot the previous established procedure to that runway - add a bit of power going into flare out of a steep 60 knot descent.
Wow, what a sinking feeling as there was insufficient energy to stop the descent, hit pretty hard on all three and bounced.
Power was on quick after that and flew out of there, went around and tried it like in the past and squeaked it on.
Live and learn, my old brain needs more flying....no damage to trusty RV 8...just my ego for letting it happen.

Something's not right. You should have plenty of energy to flare at 60 kts.

That may also depend on the approach angle.

The approach angle was very steep Mel. Granted, I did not hit aft elevator stop but the nose was quite high when runway connect was made.
No intent to start an aerodynamics dissertation here, just making the point a little power going into flare out of such an approach makes it work out much better.

David, glad to hear you made it through your "teachable moment".
On a steep approach, over trees, to a short grass runway, at 60 KTS, the dissent rate can be sufficiently high that ground effect will not provide enough cushion for a comfortable flare (assuming not flying behind the power curve).
I have these exact conditions and find I need a few extra knots or a small burst of propeller to help "mush" into ground effect.
It sounds like we have similar behaving airplanes.

Your teachable moment is my teachable moment.
Setup at 60 kts, steep approach, full flaps, mine comes down as David and Glen described. If your not careful the ground will come up and smack you. A little power right near the end helps to arrest that decent. But you two are landing on short runways (- 1500 feet)? Challenging.
I envy you guys that get to fly off grass, drop it in over trees and get her stopped. Nothing like that around here to practice on.
David, was that a wheelie or a 3 pt?

This is consistent with the behavior of my non-RV. Below a certain speed, I can change the deck angle but not seriously change the trajectory.

My RV-8 at 60 knots solo with power off and full flaps will not quite arrest the descent. But it will at 65 and float a short distance.

Also beware of the accelerated stall with aggressive flare out of a steep descent. You will get no warning. Just immediate loss of lift.

It touched down 3 point....and bounced, It would have been impossible to arrest the descent from bounce, full poser saved the day.
A little power helps break the sink, and when it touches a little forward stick makes it stay there.
