We have had a T/R belt failure just after coming in to land in the hover 2 up confined area, total destruction of the RW.
Just wondering if the Vee belt could be upgraded as there has been a lot of improvements in belt technology.
this came up in a google search as maybe a better belt for our application.optibelt SUPER XE-POWER PROHigh performance wedge belts - raw edge, moulded cogged

Oh no! im very glad you are still ok. another point for the survivability and crash worthiness of the frame. 
In what manor was the tail rotor loss of thrust developed? sudden belt breakage? slower developed like belt slipping? 

my biggest concern with the belts have always been oil/coolant contamination affecting belt drive friction... i've heard a few instances of coolant from the overflow reservoir leaking onto the tail belts. same with pinhole leaks on the engine manifolds. 

i hope you're able to find more details, i am very sorry for the loss of your ship. was this the one you've shared pictures of previously with alot of your upgrades?
