I will put my little information in here. I first flew behind a IVO in Mar
ch of 1994. Mark from Thunder Gull Fame was at Oceano airport (Pismo Beach
=2C Ca) amd had an IVO on his 2 place ultra light trainer. Got about 20 mi
nutes of dual and played with prop. During those years little was know and
got some bad information from a friend in Watsonville=2C later corrected.
I have been flying behind an IVO since my first flight in 1997=2C 1400 hou
rs. Have had several changes over the years for different reasons but I lo
ve the prop. It was neat when I joined the Desert Fox Squadron in 1998 as
most of them were using IVO props. At the present time I have a 72 inch Ze
ro Plus UL on my 912ULS. Have the newer prop pitch assembly=2C sold the ol
d one one Ebay and it was still working great. Thats the sales pitch.
I fly out of Half Moon Bay=2C Calif and the air here is thick. Air temp is
usually around 55 to 59 degress F. I adjust prop pitch on Take off to 4000
RPM's runup at 23 inches MP and that will yield about 5500 on Take Off. Th
at setting works very well up to about 3000 feet at which the air is thinne
r and enangine RPM.s start to increase. A couple taps on pitch control and
whalla engine speed drops. I fly with 5000 RPM's 24 inches MP below 5000
feet=2C above that use about 5200 to 5300 with throttle pulled back about a
nd inch. Gives me TAS about 100 Kts with a fuel burn of 4.3 GPH.
The weight of the prop is under 10 lbs and I love it. Have has some issues
in past but all problems were resolved=2C don't want to get into that now
=2C would be willing to talk if you call me. (650) 712-1802 anytime.
One note=2C on preflight check prop position by running pitch=2C you can he
ar the motor unload near zero pitch change. Nice thing about the prop=2C n
o matter what happens with motor or whatever=2C it will bring you home.
