spins from coordinated flight

: I'm sure you will. Generally for practice anyway, you can pick a long road or anything straight in front of you extending a bit into the distance. Do the roll as a slow roll but do it fast. The visuals are easy really in this scenario. Use the left tip and form a 45 with about a 4g pull and set to the angle formed by the wing and the horizon. It isn't nearly as accurate as a metal or FG tip cross attachment but close enough for government work. Do the roll quickly holding in some excessive forward pressure past knife and on into inverted. The Citabria will have a seemingly VERY high inverted nose attitude at the inverted 45 due to the flat wing and angle of attack needed to keep the airplane stable on the 45 inverted up line. As you go past knife edge switch the visual cue directly over the nose and pick up the extended reference and adjust if needed for the vertical maneuver line. Check the wingtip for the inverted 45 up line but be aware that in the Citabria you probably won't have any excess inverted up line time available before you relax the forward pressure and go through the float at the top. You should be just above stall so don't pull down, just relax the forward pressure and let the airplane float on through, then gently pull down as the airspeed starts to increase. Use about a 4g maximum radial g pull on the back side. When you can do this one well in the Citabria, you get the Gold Star for being able to fudge a 1/2 Reverse Cuban and make it look good in a Citabria :-)) We'll see! I could alwasy do them OK, just not as idily as I'd like to have. The Decathlon was OK doing them, but I always felt blind rolling at that angle with no central point, is what I was saying. Not worried about it, though. I'm gonna save this post for when I get to that point though. Thanks! Bertie |

Unless you are concentrating heavily on exactly where and WHEN to reaquire the forward cue you can easily mess it up. In the Citabria, you'll only get a second or two to set up on the erect up line before you have to initiate the roll, so you're looking at the tip as you make the initial pull. Do a quick set then do the roll. During the roll, change to the forward cue, pick up the road inverted, make a quick correction for heading if needed, and by then the airplane will be in the float. The rest is simple loop recovery. I'm certain after you manage a few nailing the visual cues, you'll do fine. Trust me. I'm not as good as Tucker, but our cat swears I'm a f*****g genius :-)) -- Dudley Henriques |
