Yes Tom, I am helping Lee with his dealership. I helped him fly our demo plane up from No. Carolina. I give his demo flights for him and will either fly new planes up for new owners or help them is they wish. We are now schedualing fly-ins to attend and dropping off literature. How is you cabin heater for cold weather flying? fly safe Bob Griffin Slingerlands, NY ________________________________ Message 2 _____________________________________ Time: 06:55:57 AM PST US Subject: Allegro-List: Allegro Cruise Speeds From: "Thom Riddle" --> Allegro-List message posted by: "Thom Riddle" Paul, at Aero-Siam asked, me about the cruise speeds I've been seeing on the Allegro so I'm posting the results of the tests I've run on our Allegro with 80 hp Rotax 912UL engine and Woodcomp 633R propellor set for best cruise speed at relatively low altitudes, i.e., 5,500 rpm at full throttle. I've attached a file that shows the actual performance numbers at various RPM settings. Please note the following: Tests were done at sea level density altitude (cold day at about 1,800' msl). The Airspeed Indicator reads rather high so I did upwind/downwind GPS groundspeed averages to get True Air Speed (TAS). Note that any change in prop pitch setting will invalidate the actual speed results. Also, with this pitch setting, I could not attain 5,500 rpm at a Density Altitude above 6,500' (~2,000 m). With less pitch the Allegro will climb better and be able to achieve higher speeds at higher altitudes. I hope this information is helpful. Let me know if you have any questions. -------- Thom in Buffalo do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=8416#8416 Attachments: http://forums.matronics.com//files/allegro_speeds_110.pdf ________________________________ Message 3 _____________________________________ Time: 07:03:45 AM PST US Subject: Allegro-List: Re: Allegro owner or pilot whereabouts? From: "Thom Riddle" --> Allegro-List message posted by: "Thom Riddle" Bob, My cabin heat is great! I was told by Frank Cuba, the Nebraska dealer that the early model heat muffs are bigger and heavier than the new ones but work much better as cabin heaters than the new ones. I've not flown a new one so cannot confirm this personally but trust Frank's experience in this. Is your cabin heat output weak? -------- Thom in Buffalo do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=8418#8418
