Here is link to the SAGPA website with a copy of the Gyroplane Review published in African Pilot in 2006. (The prices will be very out of date and the latest African Pilot Gyro review is pathetic - really don't know why they bothered? )

Every gyro (and car, and boat, and golf club....) owner will give you good reasons why their one is the best. And they are all absolutely right. It's horses for courses and much depends on what, where and how you wish to use your gyro. And like car choices - its individual, emotive and personal.
You will read about and hear lots of debates regarding various gyro options and different makes and designs. Endless hangar talk about "must have versus don't need a horizontal stabilizer, comparative airspeeds, fuel consumptions and range, baggage space, quality of finish, with doors, without doors, open vs closed cockpits, aircraft weights, composite vs aluminum rotors, price tag etc" the list goes on... My advice is to ignore all of these type of comments (for the time being). Gyro pilots, and more specifically, gyro manufacturers are past masters at obscuring and blurring "key component points" with "key selling points"!
Instead, concentrate on thoroughly researching (so that you understand!) all you can about these BIG FOUR crucial, vital and most important aspects of ANY gyro:
1. The rotor head assembly, construction & design. (materials used / stress tests & data / component time life / hub bar design etc)
2. The engine power plant. (reliability / original aircraft application purpose? / dual ignition redundancies / maintenance requirements etc)
3. Flight envelope stability (Vne / flight stability / horizontal stabilizor question etc)
4. Accident & Safety record. (Causes of accidents / "quircks"? etc Admittedly difficult to establish with newer models.)
To me, the BIG FOUR are the most important factors (beyond your own attendance to safe flying) which will give you the greatest peace of mind in your choice of gyro, and thus your flying enjoyment. Once you've more or less got to grips with these - then, and only then, should you start considering the individual options and offerings, configurations, finishes etc which will best suit your needs (and pocket). And remember - don't be swayed from the BIG FOUR by a glossy paint job, pretty frills or sales talk. For these will be the furthest things from your mind the day you find yourself in some unexpected turbulence, looking down at some very uninviting mountain top a few thousand feet below you...!
