Extra 300 bounces on landing rollout

[sbclark 55]

Hi,

When I land my default Extra 300 sport plane taildragger during rollout it starts bouncing, and does not stop bouncing until A/C is completely stopped?

Any idea how to fix?

Stop pumping the stick?  😜

But seriously, have you tried it at a different airport to rule out a scenery surface problem?

Hi Bob,

I went to a P3D V5.1 default airport, Miramar Marine Corps Air Station and experienced the same problem.

No, I am not pumping the stick at all, once I land and firmly on the ground, I let go of the stick and watch the plane bounce until it comes to a stop.

How many times have you flown it Bill? These highly sensitive planes need...sensitivity.

Ron & Bob,

The Extra 300 is my go to aircraft when testing out newly added scenery, sightseeing, or just having fun buzzing around low at 3rd party airports, etc. I like the visibility.

As to my experience flying taildraggers, I have logged around 100 hours flying Pilot In Command in real world Piper Cubs, and of that time, I have about 30 hours in a J3 Cub, which is flown from the rear seat with no passengers. If your passenger is tall, visibility is very limited. Many times I set down on short field dirt strips with a passenger in the front seat with no problems.

So I was very comfortable making either either 3-point stalls, or what we called in the day, "wheels landing," in the Cub where you would touch down on the main gear first, bleed off speed until the tail dropped to the ground. I experienced a lot of crosswind landings where I flew in he state of New Mexico in my early days........there is a lot of wind at the White Sands Test Grounds when I belonged to a Military flying club.

So, when I perform a 3 point, fully stalled landing in P3D, really close to the runway in the Extra 300, keeping the stick fully back, it bounces like a pogo stick, and does not stop bouncing until rolling to a stop. I just know it is not related to my simulator skills, or lack thereof, but some other issue. BTW, I don't experience this issue when I fly the Extra 300 in the new Microsoft Flight Simulator 2020.

Any thoughts?

My only guess is that maybe there's a boo-boo in the contact points section of the aircraft.cfg file.  I've seen add-on planes do that in other ESP sims, related to the static/max strut compression and wheel hieght params I think it was.

But I think it very odd that a default plane would do it, which makes we wonder if it isn't something else at play.  What other add-ons are in use?  Anything that manipulates acft weight or steering?
