Q2
|
My Q2, Corvair powered with white paint recently applied now awaiting the stripes to be applied. Project nearly ready to transport to the airport for
testing and hopefully flying. What I thought would be 2 years or so has been 9 years to bring to this stage. Kind of like reinventing the wheel as all who have done one of these well know. Norm Coote, Port Ludlow, WA <coote@...> Sent: Tuesday, November 15, 2022 |

Looks fantastic!
Congratulations. What prop is that? The root is very narrow. -- Q2 N86KL |

Norm------------- Your dual control system alone, must of take a while to figure out.
As for time building, the airplane I was to finish before I turned 50, was finished last year. Turned 69 in October, but the key word is FINISHED. Starting another and that will be finished before I turn 90. Have fun------------------- Chris -- This email has been checked for viruses by Avast antivirus software. www.avast.com |

Very nice work, Norm. Congratulations are well earned!

Over the years we have seen a couple of Q2's with corvair power that were unable to generate enough power on take-off (for various reasons). The corvair is a fairly heavy powerplant, so make sure that your CG is about in the center of the expected CG range. For comparison, since both you and I have 6-cylinder horizontally opposed engines and approximately the same displacement, my test numbers may be of value to you: You may also want to try what I did prior to first flight with my plane/engine combo (Tri-Q2/Jabiru 3300): Tie your tail to a spring scale and then run up the static rpm at full throttle. This way you are certain to know how much static thrust you are generating before you do your first flight. I was able to achieve approximately 300 pounds of thrust and a maximum static RPM around 2800. If you can get somewhere in that neighborhood, then I would think that the engine prop combination is adequate for a successful first flight. It looks like you have a ground adjustable prop, so you should be able to get it set up get the numbers you need/want prior to first flight. Great work! Cheers, Jay Scheevel, Tri-Q2, N8WQ 4-years and 287 hours. -----Original Message-----

How in the world did you rig for twin throttles/mixtures?

At Velocity we used a mixer gadget. Both cables from the panel come together side by side. A third cable attaches from the opposite direction. The three are secured with a bolt.
The down-side is that the co-pilot control doubles the friction, makes either control harder to manipulate, And if either control has the friction lock set, the other control cannot move either. Consider the hazards before going that way. Rick Hole |

I always wondered if the Sonex version would work: http://www.aeroconversions.com/products/throttles/index.html

Michael---------- I would be concerned about this arrangement for dual throttles. It looks like they are using the throttle cables to retard the other throttle. What happens if the friction is set to tight on one throttle? I would think the cable would flex and then act like a spring helping to keep the throttle open. If both throttles are using a solid rod to go to a rod joining the two together and then to the cable, that would be a better idea. The throttles need to be physically attached to each other so there is no independent movement.
Maybe Sonex has all this figured out and I'm speaking for nothing.------------ Have fun------------ Chris -- This email has been checked for viruses by Avast antivirus software. www.avast.com |

Sounds to me that the best throttle lock might be a single common one at the carburetor in a way either control can operate it and override the other On Mon., Dec. 5, 2022, 9:18 a.m. Chris Walterson, <dkeats@...> wrote: Michael---------- I would be concerned about this arrangement for |

Maybe run a second tube / rod inside the one running side to side and tie the 2 locks together? On Mon., Dec. 5, 2022, 9:32 a.m. Mike Steinsland via groups.io, <MIKESKUSTOMS=GMAIL.COM@groups.io> wrote:
