Was that an electric version you got cracks with?

Once the pipe tunnel is installed it removes and transfers quite a bit of stress from that area. Also the part of the fuse that tapers back from the landing gear reinforcement is removed when using a 2 cycle pipe, so, additional carbon fiber in that area would be useless because it would be removed anyway.

If an electric system is installed then the carbon fiber extended to that point or further would be useful.
