Robbe U47 equipment tray issue

[g2tiger]

This is an FYI for Robbe owners. Recently I suffered a break in the equipment tray. The break was behind the electric motor mount and forward of the rudder servo. If it had broke druing a run it would have sunk the sub I'm sure. I have since added a sub floor to the area to add strength. Anyone else encounter this problem?

I cracked the tray of my Robbie Type XXI in the same place. I braced it with carbon fiber strips applied with Stablit express, and for added insurance I installed three 6/32 threaded brass rods through the aft end cap extending to the motor mount bulkhead and glassed in with stablit express and light glass cloth. I dont think she will crack again do you?
