Evading the rules there is just far to risky. Having said that and being a Canadian living in the US for the past 7 years......the US has far to much red tape and restrictions of freedom as well. If you want to experience real freedom.....go live in Canada for a while, the REAL land of the free. -------- Ray Riverside County, CA Do Not Archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=141698#141698 ________________________________ Message 5 _____________________________________ Time: 08:14:52 AM PST US Subject: Kolb-List: Re: Ivo Props From: "jb92563" Since we are talking about props, does anyone have experience with Power-Fin props?

Between the IVO, Powerfin and Warp Drive. Powerfin has the lowest mass, the highest thrust, but less damage resistance than the Warp Drive. I don't how the IVO compares in damage resistance. I had a 9/16 x 2.5 inch bolt go thru my Powerfin with damage but it got me home from three hundred miles out. If a exhaust system goes thru the prop only the Warp Drive will get you home. Anything larger than an exhaust system will likely put an end to you flight but Powerfin will break off before causing redrive/engine damage. Note! Props are like religion, people defend their props very aggressively. Putting on my flame retardant clothing.

Opinions? As Rick Neilsen said, ditto on the damage resistance. You pay for the lightweight construction. I knew a guy who had a Powerfin on his MKIII. He was constantly getting damage from small stones thrown up by the wheels. He would repair the damage and keep on flying... until one day the prop exploded on takeoff at about 50' altitude. From where I was watching, it looked like he made the classic mistake of not flying the plane first, instead concentrating on shutting down the engine... and stalled and pancaked it in from 50'. The plane was a total loss, he had serious back injuries requiring lengthy hospitalization, and luckily his passenger (a paying customer on his first "introductory lesson", he was a BFI and the plane was an "ultralight trainer") wasn't hurt. We picked up pieces of the prop all over the airport. It appeared that there must have been some internal damage / delamination that was only masked by the surface repairs and filling he did Not the prop's fault, perhaps, I blame the repair, but still a delicate prop for a pusher with the wheels in front. I'm kinda glad I have a wooden prop on my Ultrastar. Not sure Powerfin makes a 2 blade anyway. I have a 48" 2 blade wooden adjustable from GSC on one of my PPG's, and that's definitely what I'd go for again if I was in the market for an adjustable. Lighter than anything but a Powerfin, and less cost than any other adjustable. -Dana -- -- But do you trust the _government_ with semi-automatic assault rifles? ________________________________ Message 8 _____________________________________ Time: 11:02:01 AM PST US From: "Richard Girard" Subject: Re: Kolb-List: Re: Ivo Props Ray, I have a four blade 70" Powerfin on my HKS powered trike. Ditto to all on the lack of damage resistance. I screwed up and left my bifocals hanging on the neck or my T-shirt. They slipped off and went through the prop. They were cheapy $5 Dollar General bifocals at that. Put a 1/4" divot in one blade and an 1/8" nick in another. Mighty expensive 2nd hour in the trike. I did a field repair to keep flying that evening, then grounded the ship until I got two new blades. I like it, but if you have a robust enough gearbox, i.e. "C" or "E", if we're talking Rotax, I'd go with a Warp Drive for damage resistance.

Just thinking out loud..... if you can get to the 1/8 inch hole from the inside.... put the patch on the inside and you may not have to do all the painting. It should stabilize the fabric and stop it from running... Different paint,,,, then follow directions for your finish. Boyd young ________________________________ Message 13 ____________________________________ Time: 11:02:03 PM PST US Subject: Kolb-List: Re: Ivo Props From: "JetPilot" On a trike we have a Rotax 447 and a 2 bladed powerfin. This prop is really nice on the 447, very quiet and smooth and lots of thrust. We considered a warp drive, but it is just to heavy for the B box on the 447. The hub assembly and the way it goes together is very nice, very simple and foolproof. A 447 does not have many parts to come off, so I'm not to worried about putting stuff through the prop. We do keep an extra blade just in case though, it was only a little extra, and if we pick up a rock we can have it flying again within half an hour :) I have a 3 blade Warp Drive on my MK III with a 912 S. The 912-S has a is a lot more complicated, harder to catch everything in a preflight, and has a lot of stuff that can come off, and I would only want a strong warp drive on this engine. As far as damage to the engine, consider this. If you have a weak prop on a plane, and you put something big through it, the prop will probably explode and OVERSPEED your engine like crazy. So to think you are protecting your engine from damage by having a weak prop that will break is just foolish. Chances are you will do far more damage to your engine from the overspeed than from an impact with a muffler or something similar if you have the strong warp drive prop. If the 447 could handle the weight of the warp, we would have put a warp drive prop on that engine.. Wooden props suck, they are very weak, even weaker and more prone to damage than the powerfin. We had a wood prop on the 447, it broke horribly with just a very slight impact by a strap bouncing off the tip, not catching, just bouncing off the tip :( The wood prop was also much louder and had worse performance than the powerfin. Wood comes loose at the hub, and changes balance with time. The powerfin is far better in every way than a wood prop. I would never ever buy any kind of wood prop.

I lived in South America for 3 years and could not imagine how much more freedom I had. Here in the US, from the time we are in grade school they tell us we are free, but that is a bunch of garbage. We have become controlled in every way, from every direction. From lawyers making sure we can never do anything without fear of someone being sued, to just way to many petty needless rules. It has become the ingrained in our society. The sad part is, most people in the US have no clue how much freedom we have lost as they have never known anything else.
