It's the parts shooting out of the engine at high speeds that is the danger in an "uncontained" turbine failure. If the parts stay in the engine then there is no real danger, but when they pierce through the engine housing traveling at high velocities there is a possibility for injury/death/property destruction. Uncontained turbine failure has brought down full scale planes:

In 1979, a United Airlines DC-10 suffered a catastrophic center engine turbine failure (#1 compression blade assembly) where the exploding parts severed the main tail flight control hydraulics.

Because the model engines have to be light, the exterior housing probably isn't going to put up much of a resistance to a 100,000+ RPM chunk of metal!
