I would beg to differ, and would also recommend that you go and do the microlight instructors course, but if you are planning to instruct on a three axis microlight do the course on one, with a microlight instructor who is experienced at training instructors on a three axis microlight.
Flying a microlight is very different to flying a conventional SEP such as a C152 or a PA28. A microlight is far more susceptible to the weather conditions. It has less inertia and therefore far less penetration into a head wind in the event of an engine failure. It is affected far more by thermals, crosswinds and head and tailwind components. Microlight pilots are more likely to want to fly from short grass strips, to operate in a non radio environment and want to know how to maintain their own aircraft to the limits that legislation allows.All of the training you give them will be like teaching someone to fly a conventional SEP with all of the gyroscopic instruments covered up, you cannot reference to the attitude indicator because they probably will not have one, or a direction indicator, you have to teach everything by looking out of the window at the horizon. It doesn't matter if you have a CPL or ATPL, it doesn't matter how good you are at drawing pretty pictures on a whiteboard or using a power point presentation. You need to know about grass roots aviation, about how to clean a spark plug, and how to service a rotax engine, not about frozen ATPLs and how many instructional hours you should do to make the airlines want to hire you.
