It is inspired by several turbine models such as the PushyCat, Excalibur, and of course the HobbyKing FlyCat.\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin-top: 0px; margin-bottom: 1.25rem; color: #525252; font-family: 'Adjusted Cyrillic', Barlow, 'Helvetica Neue', Helvetica, sans-serif; font-size: 15px; background-color: #ffffff;\"\u003eThe CoCat has both the looks and the sound. While working on the intake and thrust tube to achieve strong static thrust for easy hand launches, the sound developed into a very satisfying whooosh. This jet quickly became my favorite go‑to model.\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin-top: 0px; margin-bottom: 1.25rem; color: #525252; font-family: 'Adjusted Cyrillic', Barlow, 'Helvetica Neue', Helvetica, sans-serif; font-size: 15px; background-color: #ffffff;\"\u003eAs with all my designs, I created it with ease of use in rough flying environments in mind. It is easy to hand‑launch, easy to land on tough grass, handles gusty winds with a gentle character, and has a very wide flight envelope. From slow flight to unlimited vertical. The CoCat does it all.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eVideo on my youtube channel\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin-top: 0px; margin-bottom: 1.25rem;
