I replaced my Warp taper tip ,nickel edge with a lighter Kiev. In addition to a turbine smooth engine in cruise, the shutdown is flawless which it sure wasn't before ! AND at very low rpm there is no longer any gearbox noise. The Warp now makes a good wall mount decoration for my hanger. Anyone want to buy it ? It has the hub for the early mid 90's 912UL. Dick Maddux Milton,Fl ________________________________ Message 2 _____________________________________ Time: 07:54:38 AM PST US Subject: RotaxEngines-List: Re: 912ULS Shudder on Shutdown From: "lucien" Though I never had that problem with my warp drive (68" 3 blade), I now have a powerfin F model (70" 3-blade) on my tornado/912ULS and it's smooth as silk at idle and shutdown. I did talk to Daryl at WD back when I was trying to debug my vibration problem with my WD and he assured me it was within the MOI limits of the 912 gearboxes. And like I said, I never had any kind of problems with mine. The 3 blade IVO medium that was on the plane when I bought it, tho, was a different story. The idle was significantly rougher and the engine seemed to spin for an eternity after killing the mags. But that thing weighs almost a full 10lbs more than my Powerfin! I checked my friction torque a while back and it was about 450in/lbs, somewhere in there. About the middle of the range Rotax specifies anyway. And there was no problem with the Warp Drive on mine. So perhaps it is a low friction torque on the box?

From: "lucien" Does anyone know if the 447 and 503 have finally been discontinued? I noticed that BRP no longer lists them on their web site, i.e. at: http://www.brp-powertrain.com/en/desktopdefault.aspx/tabid-201/356_read-319/ you only see the 582 and the 912/914. Also some places like CPS don't have them listed in their engine sections anymore. I know the 447 was on the chopping block, but I thought the 503 was going to stick around for a while. Just trying to decide if I should just go ahead and sell my 2-stroke toolset and just make some other decisions about future planes, etc. Thanks, LS -------- LS Titan II SS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=350908#350908 ________________________________ Message 4 _____________________________________ Time: 08:37:12 AM PST US From: TheWanderingWench Subject: Re: RotaxEngines-List: 447/503 discontinued?

Well guess I'll have to go into mourning for a while then. I was thinking about a 503 powered plane for my next plane, but even with 10 years of parts support, that would cut it pretty close. My planned project would have still been a few years out before I could start on it. Fortunately, tho, that means I get to keep my titan ;).

You might send an email to Mark Smith at Tristate Kite sales: http://www.trikite.com/ He's been using the 582 for decades (since it came out basically) and I think he uses car radiators pretty much exclusively. So he'd have the definite poop on which radiator to use.

Go to a junk yard and pick up a small used radiator. You can use any water temp gauge for the most part that was designed for that. -------- Roger Lee Tucson, Az.

What you want is the radiator from a Honda Sabre or Magna motorcycles. I've converted two 582 powered Kolb Mk III's and both work perfectly even in the Kansas heat. See the attached article I wrote for the newsletter of our local EAA chapter.
