This interest must be legitimate. Perhaps, but I'll bet that if you read each post that includes the word "sensitivity" or the phrase "pitch sensitivity", you will find that most folks are either questioning rumors that they've heard, or else kicking around ideas for reducing the rumored sensitivity... not actually discussing having experienced it or presenting sound analysis of its existence in the design.

[mailto:paul.conley@wcom.com] Sent: Monday, June 17, 2002 9:15 AM To: 'krnet@mailinglists.org' Subject: KR> Injectors / Carb Daniel, I run a Posa. (I am not endorsing! I know ...one of the few that does seem OK) Any way, True Posa isn't a normal "carb".. I recken I would simply call it a metering device. Unlike an injector setup, it has no monitoring of Throttle position or airflow. It simply relies on the Venturas vacuum to assist the pull of fuel from it's main jet. Carbs rely on a float bowl w/ needle and seat to shutoff fuel when the bowl fills up. This bowl of a carb then supplies the correct fuel height to draw fuel from ..through the main and Idle passages. An injector is either mechanically or electrically "opened" to allow fuel from a high pressure source to squirt fuel into either the cylinder or an intake manifold of sorts. Typically either one injector per cylinder or a couple mounted into a throttle body.(The latter really resembles a carb) Either case, airflow is monitored by a throttle position sensor and a mass airflow sensor. These two monitorings can then "tell" the injector (computerized or Bosch mechanical style) how long to stay open and therefore how much fuel to dispense. Hope this helps !

Yep, that's why it's stuck to the outside, rather than to the front of the vertical stab's front spar, where it would have probably worked better and would have been better protected. About two months before I built my vertical stab I reminded everybody on KRnet not to forget to put their antenna on that vertical spar before they built the stabilizer...

Message-ID: <002001c216ed$613022c0$37000a0a@oemcomputer> Putting the antenna in the fiberglass/wooden fuselage will work perfectly. It is reasonably important to keep it at vertical as possible, since the FAA antenna you will be talking to is vertical. If you look at the losses in small diameter coaxial cable, you will find that the loss going back to the tail to get a "perfect" straight antenna is greater than the minor signal loss locating the antenna in the fuselage. Besides, you will be able to get to it if you need to. My main concern with mounting the antenna in the tail is that you should run the coax feedline 90 degrees from the antenna for about 1/4 wavelength (22 inches). Hard to do in the vertical stab. This means that the coax feedline will be capacitatively coupling to the counterpoise and screws up the impedance match. Putting toroids around the feedline near the antenna helps, but such a layout will affect the resonant frequency with some screwy anmalies as you change frequency. If I can help more, please call.
