I received this from Robin Taylor at Viking.
One of the more interesting birds I've never seen in person... but wanted to.
THANK YOU rbrochey, I have forwarded this to the two guys who are flying the Cygnet at our EAA chapter. Maybe they will fly the airplane in to that meeting.
Our guys have started flying the Cygnet in the Young Eagles program, which was the entire reason it was donated to us
Any news about the Cygnet in that Young Eagles program?
Yes, the guys are using it to fly Young Eagles on a fairly routine basis. At my insistence (pay no attention to that shotgun in your back) they are being very conservative, any little mechanical or operational issue grounds them until it is resolved.
It runs a little warm when the OAT gets high, and once or twice this has resulted in them putting the airplane away for the day before all of the Young Eagles were flown. But the majority of the time it was not an issue.
It is proving to be a perfectly good little airplane. A little funky and unusual, but it flies correctly and has proven to be reliable thus far. I admit to being overly suspicious and trigger-happy about it, but this is only because we are flying in and out of city airport surrounded by houses.
My experience flying it was very very limited, one 30 minute first flight, and then the guys took over from there. But I would not hesitate to fly it again, so long as I was confident in the reliability of the engine and associated systems. Those things are of course the most common problems.
i just wish the design was a little bigger to accommodate an O-235 or Corvair and the fuel tanks in the wings. I still like it though.
The 80 HP Rotax 912 would make that airplane a really neat little mahcine with pretty good STOL capability, with a little personality and character thrown in to make it unusual.
If you or anyone else wants to build one, I would strongly recommend against the original windshield/canopy/door setup. That is the one thing about this airplane that I didn't like.
How would you revise that setup Bill? Forward tilt, slider?
One piece blown canopy mounted on parallel arms, which swing the canopy up and aft, resting on top of the turtledeck behind the pilot compartment.
Emergency release would be designed such that the canopy would tear away after it raised upward and rearward enough that it would not whack the occupants in the face.
I was pondering on that one for a while. I was leaning more toward a T18 style canopy. Your idea would probably work really well with gas struts forcing the canopy upwards against the airflow. Emergency handle could unlock the front end initially and fully pulling it could unhinge the aft end.
I tried and tried to get the EAA chapter boys to see the value in the upward swinging canopy, and got nowhere. I would not want to own the Cygnet without that feature. The shoulder wing isn't bothersome, the forward sweep isn't bothersome, and the geodesic wing structure isn't bothersome. But the entry/exit is where this airplane comes up short with me.
I agree with the fuel tanks in the wing from a safety perspective, but I would very strongly suspect that the wings are not high enough for wing mounted tanks to provide gravity feed to the engine at a high AoA. I didn't much like the fuel tank behind my head, but it is high enough to feed the engine with gravity. That's probably why it's there.
The one we have looks a little ridiculous with 5.00 x 5 tires. Kinda needs the Carlisle 8.00's on it as far as I'm concerned. The small tires work fine, but the airplane would just look right with 8.00's.
And as any high end doctoral degree aero engineer will tell you, if it looks right...
Here is mine sitting on 21x8 tire. I like the look of this tire and she rolls so much better with these installed.
Now THAT looks really great !
How many Cygnets show up at an annual gathering?
Entry and Exit when on it's wheels is simple! I just upgraded at annual from 15" low profile to standard 6-600. The difference on turf is remarkable. Easier to turn tight too! If you are logged in or click on the picture below you will see how easy it is to get out. In is the reverse. P130 has a window you describe looks heavy and weight is the bane of a LSA with a VW prop limit of about 58-61".
That is a 21x6 tire not a 21 x8.
When entering on the left it is left foot on tire, right foot on step, right foot in, then left foot in. If entering on the right it is, left foot on tire, right foot on step, left foot in, then right foot.
