I had noticed that the conical bearings were very difficult to get freely turning and at the same time just the right tightness.

Sorry to hear that! I can't image how tramatic that would be. Glad everyone was ok.

shouldn't we be collecting data?
Ian, not sure if you'll see this....but when you feel like talking about it, can you elaborate on what happened? Just for the eductional component of course. I am nervous fast taxi-ing across asphalt seams, but it would be good to know that an actual flip requires 40 knots and a big gopher hole or whatever.
If it truly takes only 5 knots and a banana peel, then I am inclined to ground my bird until I have all the mods installed!

Ian you have the courage to post it man. Appreciate it. I am with Perry please share more if you can. Sometimes I land on very aggressive surfaces it's never too late to learn.

It breaks my heart to hear that news ...
My first flight was Sunday and the nose gear "issue" is my biggest fear. I too would like to understand the conditions at the time of your incident, but only when you're ready to talk about it. Again, so very very sorry ....

Just saying that you flipped without details...especially the surface...is not helpful.
I avoid grass...period. I have taken steps to minimize the chance of this happening and with about 1600 hours in a 6A, I cannot agree that this is a "but for the grace of God" situation.

He did say he was going a bit too fast, and not holding full aft stick.

Maybe a factor, but I doubt it was the root cause. The surface is the most likely causal factor in my opinion.

Sure surface can be a contributing factor but I believe it is only one of the many factors that can cause the collapse of the front nose gear. I will say this, I believe "AntiSplat" is onto it. Their gear leg device helps to make the front leg more robust and will help it withstand the abuse it can receive (except perhaps from Gopher holes and anything else that will allow the fork nut to dig in but their skid plate may help here). As long as the front wheel is spinning I believe the surface can be as rough as it likes, as long as that nut does not dig in. And the key word here is "Spinning". If the wheel is spinning when it touches down it will deflect that front leg less as it "spins up" to aircraft speed. Holding the front wheel off as long as possible will allow more chance of the wheel doing about the same speed as the aircraft when it touches down. A wheel pant fitted and a free spinning front wheel axle assembly will have the front wheel spinning when it touches down. If the front wheel drops into rough surface rut on touch down or on roll out, as long as it is spinning it will pull itself out of that rut.
Here is a post from another thread where I was asked my opinion of the AntiSplat leg device.
[I fitted the "antisplat" recently before the wife started training in our 9a. I know some people do not believe in the product but my wife in her training has given the front a real workout with a couple of wheel barrow jobs .
And I had to do an off field maneuver once to dodge some "Roo's" that were hiding in the late afternoon shadows. It was late roll-out when I saw them and I went through some big bumps in avoiding the Roo's. I hit my head on the canopy and was expecting the front leg to go "splat". But the device did it's job and you can see where it has been working on the powder coating.
For nothing else, it was worth the cost just for some piece of mind coming into land at some unfamiliar bush strip. For me, it allows me to concentrate on the landing at hand, instead of trying to see what the condition of the surface is.]
Most of my flying is into bush strips as that is where I believe most of the fun is.
