Got to fly a light sport aircraft
At our 2-day Big Kids Toy Show fly-in last weekend, I had the pleasure of
flying a "CT" with their demo pilot. If you're not sure what a "CT" is, see: http://www.fly-flightstar.com/pages/ct.htm You can also see some pix of it he www.BigKidsToyShow.com I'm here to tell you, this thing is an *airplane*. For some reason I had the impression that an LSA would be fragile, slow and more like an ultralight than a certified aircraft. I couldn't have been more wrong. The CT looks like an egg with wings, sorta like a pregnant Cessna 150 made out of carbon fiber. I figured it would be tight inside, with two nearly 200 pound guys -- but I had as much or more shoulder and hip room as in my Pathfinder. The seats were semi-reclined, but adjustable fore-and-aft, which was nice. (I hear some LSAs have fixed seats, and adjustable rudder pedals.) The plane has dual sticks, and I was in the right seat, so I was not only flying right-handed, but with a stick -- neither of which I'm used to doing. Luckily, I'm ambidextrous, and always fly video game joysticks right handed, so I quickly got used to flying from over there. Visibility is nothing short of spectacular. The windows come down to your hips, and the high wing gives the impression that you are just sitting in space. Climb performance was very impressive, with a solid 600 fpm climbout, even with 400 pounds of people, plus fuel, on board. We were able to sustain zoom climbs of over 1500 fpm for over a minute, so you can get up pretty quickly once you're at cruise speed. The controls were very well harmonized, and felt very crisp and clean. I needed very little rudder, and the ball stayed centered. It's just a nice flying machine. We did slow flight and a stall or two, and the thing literally stands still before it stalls. I think we saw 38 mph before it broke! Landing was simple, and it's got electric flaps -- something I didn't expect in an LSA. Again, this is a real airplane, and seems quite ruggedly designed. And it's pretty fast, too. We trued out at 130 mph, burning something absurdly low, like 6 gph. And it burns car gas, too! I'll tell ya what -- when our kids are grown and gone, I can easily see us owning a CT. It does everything I want in an airplane, and uses less than half the gas Atlas burns. It's a great flying bird, and Mary thinks it's cute! Finally, the CT gave more demo flights at the show than the Columbia, the Travel Air, and the Pitts *combined*. Everyone seemed intrigued by it, and that demo pilot must've put 10 hours on it over the course of the Toy Show! I think LSA planes like this one will really have a shot in the market -- once they change the minds of previously-prejudiced people like me. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

I'm picturing a system where the engine can be started and run without turning the prop, then engaging the prop clutch to spin the prop. What are the advantages (other than being able to warm up the engine on the ground without spinning the prop? Of course the disadvantage would be decreased useful load. (extra clutch weight). But maybe I just made a completely wrong assumption on how a prop clutch is used. Regards, John Severyn @KLVK |

a system where the engine can be started and run without turning the prop, Nope, sorry. My ride was more of a "thanks for helping us get here" ride, rather than a "please buy this plane" ride -- so we just went up an flew the thing. We didn't discuss systems at all. It sounds like a good idea, though. Anyone here know? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

I think LSA planes like this one will really have a shot in the market -- once they change the minds of previously-prejudiced people like me. yes these are "real" planes, without a doubt, the one that had the most "ultralight-like" feel to the cockpit was the Allegro, but that was really only because of the steal tube fuselage, and the resulting framing here and there in your view, but it still flew like a real plane. I've flown the CT, the SportStar, the StingSport, & the Allegro. All were "real" airplanes, as real as the Bonanza, 150, 172, RV-9, and Sonex that I've flown. The recent EAA flyin in Texas had a StingSport as the winner of the "longest Distance" award from Southern California to Hondo, TX; so that's about as "real" as it gets. -- -- ET :-) - Student pilot, slowly working toward ppl.

It sounds like a good idea, though. Anyone here know? I am certainly not an authority on the subject, but I'll tell what I remember reading, or hearing about it. It is just a slipping clutch, that allows the engine to come up through starting RPM's, before it engages, then stays locked throughout the operating range of RPM's. The starting RPM's produce a torsional resonance that would shake the engine, gearbox and clutch, so badly that it could likely destroy something in the drive train. Allowing the prop to not be connected while the revs come up avoids the deadly resonance range, so the drive system can run normally, when it is above the bad RPM range. I think that in this case, it is not unlike (but still very different) than the clutch on some automobile's cooling fan, as I recall. Once again, I may be totally wrong on all of this. -- Jim in NC |

After parking planes all weekend -- and staring right at the spinners at the center of some really big Ginsu knives -- it's quite remarkable how much our engines get tossed around during shutdown. Some of them appear to rather violently move over 4 inches off-center while enduring the asymmetrical loads during engine shut-down. A clutch is one more thing to break -- but, wow, if it can eliminate that violent twisting motion that our motor mounts and airframes must endure, it might be a good thing? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Could be, but it is interesting that the "sport" version does not include
the clutch. I'm still wondering how/why. John Severyn @KLVK "Morgans" wrote in message ...

"Jay Honeck" wrote A clutch is one more thing to break -- but, wow, if it can eliminate that violent twisting motion that our motor mounts and airframes must endure, it might be a good thing? Indeed, it is a good thing. The problem is that the weight begins showing up as another problem, again. A clutch for a 300 HP engine is going to be much more that 3 times heavier, than a clutch for a 100 HP engine, I'll bet. That clutch is yet another example of how Rotax can make their engines so light. Spin them fast, to get more HP per cubic inch. Use a gearbox to make the power useable by a prop. Make that gearbox as light as you can. In order to make the gearbox light, (it is the weak link in all of this) protect it from harmonic resonance loads, by using a clutch. Beautiful engineering. Problem is, I'm not buying the whole design philosophy. But you knew that, already. g -- Jim in NC |

It was smooth, responsive, powerful, and quiet. If I was single, I'd buy a CT in a heartbeat. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |
