Do you have Simulink? That's perfect for these sorts of multi-rate control tasks.

Use "Rate transition" blocks for transfer of data between your inner loop and outer loop. For the data going into outerloop from inner loop set the rate transition block output rate as that of your outer loop and vice versa. Should work perfectly as I have worked on similar flight control system models. Get back in case you get stuck somewhere.
See here for details on rate transition blocks.
