Tailstrike with Logo 500 3D.

[Mr.Andersen]

Today i appearently had my second tailstrike with my Logo 500 3D.
The first one i thought was from a small stone hitting the tailblade at the landing the flight before my first tailblade delaminated in the end of a rainbow.
Today i got the same clicking noise and mushy tail after doing a rainbow again but these time there was a chip missing from one of the main blades and the tailblades was brand new.
The heli have 214 flights behind it with Rotortech 560 main blades and Edge 92 tail blades.
I have not changed head dampers since i build these heli.
Can that have something to do with the problem ore is 560 on main and 92 on the tail just to close?

Have ordered hard and medium dampers and 85 tailblades just to be shure.
Thinking about it the heli have fealt a bit mushy doing hard manouvers.

I would almost say it is time for new dampers, with that many flights.

And those 560s/92s have been there the whole time? And no issues till now?
Just sounds like some worn parts.

[Underscore]

Do you have the quick-uk tail? It seems that the blade grips are larger than the stock ones.

[Mr.Andersen]

The 560/92 combo have been flying fine for over a year estimated 150 flights ore so.
Before that i ran 550/92 without any issues and the tailgrips is stock.
One more thing i discovered taking the bladegrips apart last night is one broken thrust bearing with grooves after the balls on the race and and the cheald holding the balls together allmoust gone.

With that said i do alot of cold weather flying and the bladestrikes have happened on sunny worm days making me consider dampers as they get softer when wormed up.

[Mr.Andersen]

Today new dampers, thrust bearings and 85 tailblades arrived and after thinking fore a while im not going to test out the 560/92 combo again, just to close.
As im advancing i fly harder and even if i have gotten away with that combo for 1 year and survived two tailstrikes doesnt mean the heli will survive an other time.
So then i have these options until i convert it to a 600.
550/92 ore 560/85.
How does 85 tailblades hold the tail with a short boom and 560s?
