from http://magniusa.com/m-24-orion.htmlWhen I tried it we cruised at around 80, the closer you get to 100 the more it vibrates which is why I think 80 is a sensible cruise speed or 130kph
|Maximum speed||105 mph|
|Cruising speed||90 mph|
Dave, you be the judge: 915iS at 4700-4800 RPM, MAP 31-32, GPS 3D recorded speed 83-88 MPH, wind speed - 0 MPH, Fuel Flow 5.0-5.1 GPH:I test flew a M24 to buy, and beautiful gyro. However, cruise was in mid 60s mph so didn’t buy it. I assumed the prop wasn’t pitched for climb instead of cruise. 90mph is on the slow side for me for long cross country trips. 100mph is ideal. !
That's too much for the M24, a gyro with a large frontal area, well suited for relaxed sightseeing flights at moderate speeds. The green arch of the anemometer starts at 55 km/h and ends at 140 km/h (87 mph)... A reasonable cruise is 100 km/h (62 mph) @4600 rpm.If the M24 can get 95mph or more cruise with reasonable rpm and MAP then that would be ideal for cross country trips.
Xavier, check the video from post #14, to me it seems pretty reasonable: 915iS at 4700-4800 RPM, MAP 31-32, GPS 3D recorded speed 83-88 MPH, wind speed - 0 MPH, Fuel Flow 5.0-5.1 GPH:That's too much for the M24, ... A reasonable cruise is 100 km/h (62 mph) @4600 rpm.
