My old frame is >200 flights and is getting soft. Finally end its life on a crash from a low piro-flip. You can see the broken site and the surface area is less than 2mm x 8mm . This also contributes to the torsional weakness.
The new frame has new hex screws, better one way shaft bearing mount.
With 7s A123, the new fiber canopy fits perfectly without modification.

The new 61T is much harder and is not worn after 20+ flights.
