glide ratio

Hi Drew

"some" airplanes not the Rebel ;) Yes this thing comes down pretty steep.
If my VSI is accurate, I get about 8 or 900 fpm at 60 knots which is
about a 7:1 glide ratio. Barely over a mile glide from 1,000 ft with no
wind once I'm back to 60 kts. It sure doesn't seem like much but small
Cessna's are also only about 8:1 glide ratio aren't they ??? It is nice
to be going so slow if you do have to put it in a field though.

Cecil was saying that he has MAM researching slightly thicker amphib
nose gear legs due to a couple of incidents he's seen of bent/ broken
legs where the bolt goes sideways through the 5/8" thick leg. Apparently
the legs are high strength 7075 aluminum. I am beginning to think that
it is not the best idea to operate the amphibs on grass strips!

I had some fun and expanded the flight testing a bit this morning. A
windmilling 3 blade Warp prop seems to be a fair bit of drag at cruise
speed on 119R as expected, but at 60 knots there is surprisingly little
difference in descent rate between slow idle (600 prop rpm with closed
throttle) and a stopped prop. Some airplanes glide significantly farther
with a stopped prop but apparently mine is not one of them.

Hi Ken I don't think you should ever use the term significant glide when
refering to any rebel :)
