I have flown 2 different Kaos's and both have been a dream to fly... They will do any pattern type maneuver you can think of including knife edge flight. They are a very versatile aircraft as far as performance... it will fly fast with a hot .60 at full throttle or can almost be a low wing trainer flying mild at low throttle. Verticle performance is very strong on both a .60 2 stroke or a .90 4 stroke. VERY nice planes and a lot of fun.... you will enjoy it. Let me know if you have other questions.
