I flew with it that way for a month and the second side went to 0. I checked the guage , as per instructions, with a meter, and it said it was bad. Ordered a new one from sky sports and installed it ,using my old sending units. At that point I was back to having a reading on one side. I still need to check out ,or run new wiring, but I was wonder from you guys, how often do the sending units really go bad? Is that a common problem to cause no reading at the guage or is it usually found to be a wiring problem? The guage is ok as when I switch wires on the back, the sides that read and dont read , reverse. That leaves it to either wiring or probe. Still need to run more tests to find the problem but as I asked ,I was wondering how many of you have had to replace sending units?

The real problem is that now you are going to have to rebalance them and hope that your added weight is lighter then what you cut off so your not overstreesing the roots of the blades. John H: I believe that the foam inside the Ivo is Clark foam, a closed cell foam with very high density. It is impervious to pretty much anything so you probably don't have to cover the ends, though I always thought it would look better. It is nothing like Styrofoam. The warp drive with its solid carbon construction would seem an ideal blade for this kind of shaping... although it probably isn't easy to grind carbon fibers Topher ________________________________ Message 4 _____________________________________ Time: 08:05:12 AM PST US From: "John Hauck" Subject: Re: Kolb-List: Prop tips --> Kolb-List message posted by: "John Hauck" > The warp drive with its solid carbon construction would seem an ideal > blade for this kind of shaping... although it probably isn't easy to > grind carbon fibers > > > Topher Topher/All: No problem working with carbon fiber Warp Drive blades. I have cut them with a band saw, repaired dings with JB Weld (the JB Weld was much harder to sand than the carbon fiber). Don't think I will modify my new prop tips though. john h ________________________________ Message 5 _____________________________________ Time: 08:43:33 AM PST US Subject: Kolb-List: q From: Russ Kinne --> Kolb-List message posted by: Russ Kinne Kolbers A suggestion -- at least one member of a group XC flight might carry a roll of fabric-repair tape. This is lightweight ripstop nylon, 2" wide with a good adhesive on the back. I used it on a parachute for a couple years without any sign of it's coming off. May also be called "sail repair tape", comes in red, white or blue, find it in boating stores or sport-parachuting centers. Cut off the corners -'coffin-corner' it - so it won't start to peel up. And I hope you never need it!

It comes in several colors and is fairly cheap. It can be bought at most hardware and some grocery stores and is sold as "Duct Tape". I have been using it the last 400 hours as the inboard two feet of my aileron gap seal. The heat can get to it in the summer but replacing it only takes a couple of minutes.

The military has "90-mile an hour tape", sort of duct tape on steroids; about twice as strong, and OD in color; available in surplus sources. For fabric repairs Spinnaker tape would be much better, even tho it's too light for many other uses. ________________________________ Message 8 _____________________________________ Time: 04:07:58 PM PST US From: "Jo and Larry" Subject: Kolb-List: Lexan --> Kolb-List message posted by: "Jo and Larry" What is the thickness of the Lexan used on Kolb enclosures?

How does it work on a 582? What kind of heating systems are you using? I was thinking of using a water heating system. But I'm not sure how well that would work without using a thermostat in the cooling system,and I don't like doing that on a model 90 582 (non bluehead). I'm open to any ideas. -- Earl
