I'm with Genghis on this 1, Microlights are strictly VFR, no instruments to help you if you happen to become IMC. I operate a Thruster (purely for the fun) with a 80hp Jabiru and in the conditions described, it would be far from fun, I have A IMC rating and would'nt dream of flying into a storm, even in my AA5A, which is IFR equipt, let alone a Microlight.
