I havn't had vapor lock problems with the pure gas when it's been available, but don't know what the effect of ethanol would be. The plane is a titan tornado so the whole thing is sitting out in the breeze. The plane sits a lot more this time of year as well (spring/summer is almost always nasty flying weather) so I'm more inclined to keep 100LL in it in these times. Otherwise, I think I'll just continue to use a blend, hopefully that'll mitigate the bad effects of both ethanol and the lead..... or maybe it'll multiply it, who knows with my luck ;) LS -------- LS Titan II SS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=194140#194140 ________________________________ Message 2 _____________________________________ Time: 05:41:18 PM PST US From: "carl" Subject: RotaxEngines-List: Re: Rotax 912 Ivo In Flight Adjustable Combo. I have a 701/912/amphib with a warp three blade which has given me good service for over 500 hrs. I adjust the Warp at 8.5' for general flying and 10.5' for long Xcountry flights. I'm thinking of trying an Ivo in-flight adjustable to eliminate the required changing of pitch. I've read some negative comments on the net concerning Ivo propellers and wondered if anyone has had good results with the 912/Ivo combination? Please reply on the list or directly to me.

The Ivo is a great prop except for one thing: the stainless steel leading edge tape. You have to replace it often, and it starts to crack after about 10 hours. I don't have anything to compare to but I bet some other props are smoother running, if they have leading edge protection permanently installed. You can run without tape, but the leading edge will erode if you fly in rain or snow. The Ivo prop itself is very strong and durable, super easy to adjust, and though I have no experience with the in-flight adjustable I think it works fine. A friend of mine has one for sale (just the adjustable motor and linkage, not the prop).
