At this point during this thread, if you do decide not to become a Rotorcraft Gyroplane CFI, obtaining the Commercial Rotorcraft Gyroplane ticket is still a great benefit. If at any point in the future you decide to desire to fly Helicopters, you will be adding only another "class" to your Commercial Rotorcraft ticket. This means you need to only need to train to proficiency in a helicopter with no minimum hours required. You've already met all the rotorcraft x-country, night time hours requirements, and such in the gyroplane.
Here's another benefit in having the Commercial Rotorcraft Gyroplane rating. You have the rating in your pocket and you decide to purchase yourself a gyroplane to fly for your own pleasure. 500 hours later, you decide that you desire to obtain that Commercial Rotorcraft Helicopter Rating and fly helicopters for hire. After training to proficiency and passing the Commercial Helicopter checkride, you are a Commercial Rotorcraft Gyroplane and Helicopter pilot with 500+ hours of logged rotorcraft time in your log book. Insurance companies and employers look for total rotorcraft time. There are a number of people in this forum over the years who have successfully obtained commercial helicopter jobs with the majority of their rotorcraft time in gyroplanes. With the continued shortage of commercial pilots in all categories of aircraft, this is the most inexpensive route to obtain the necessary minimum aircraft category hours.
