There were no engine oil pressure issues or any indication that there was a problem with the filter. I was using straight weight Aeroshell 80 and changed the oil in May so there were no cold starts. I have switched back to Champion filters since that was my SECOND Kelly filter to collapse. This month's Aviation Consumer has an article on oil filters and rates the Kelly filter dead last. I talked with Mattituck's engine guru, Mahlon Russel, at OSH and he thought the problem was entirely with the filter.

Made by either Michelin or Goodyear. Remember to use talcum powder when putting the tubes inside the tires and (from experience) slightly inflate the tube then mate the 2 wheel halves to minimize potential to pinch (and tear) the tube when torquing the wheel together. grumpy N184JM do not archive On Aug 12, 2009, at 12:39 AM, Dave Leikam wrote: > Van's does not have any Lord engine mounts.

I didn't pay too much more than the Vans price, but got Goodyear flight custom tires, and the leak proof tubes (the name was a little different than that though). They arrived in a couple of days and they added in a big bag of tire talc too. I too am waiting on Lord mounts. It looks like I am just going to have to get the credit and buy them on my own if Vans is going to procure any to provide in the kits.

My original tires I think lasted 300 hours or so, and although I would have done better maybe with better tires, it's kind of nice to have them be "expendable" tires that you go with initially. Not that everyone will need this or see it that way. I know I also went through the first set of brakes faster. I'd highly recommend that once someone is flying, you order a replacement set of brake linings right away and keep them on hand. It'll be a while before you need them, but some of these things you want to have ready because they day you find that they're shot, you may want them done immediately. So get the rivet tools, rivets, linings, and things on hand early. Anyway, just wanted to point out that having the cheap tires for the first part of your flying might not be all that awful....you'll use many sets through the plane's lifetime, so lots of opportunity to upgrade.

You have to reach inside the cabin to unlock the right door. I'm planning on following that model. e.g., right door will have an external handle but will lock internally (I'll get a pin into the interior door handle which will prevent the latch pin from being pushed in). Said pin to be removed while in flight (emergency access issue). Yes, this means in the left side, then walk around to the right, to help passengers if needed. But I always get in first anyway, do pre-flight, etc., while passengers watch from the shade (or stay in shelter from rain and cold)!

Why do you ask? I want to know when I start to get some sag in the front rubber shocks. As I have posted I have a shimmy in my main wheels. I talked to Ken and Van at Oshkosh and they both said that shimmy in the main gears is common. Van said that he had it as well and unfortunately there is not much I can do for toe-in. I have talked to a few people about the design of the main gear and it is far from being optimal. Van's words to me was that it is not the optimal design for stiffness but they are inexpensive to manufacture. That is OK and I don't feel like it is a safety issue. Ken did say that you could re-align your gears and use a 7/16" bolt if you wanted to try and change the toe-in. Another factor that changes over time is the sag in the front gear which changes the geometry of the toe-in as the front gear begins to drop. Both the front gear leg sag and the application of the brakes causes more toe-out to occur. Depending on the results we get I may try to replace the front rubber bumpers. I will also call Ken and try to get an engineered measurement. Anyway, it is a number I wish I gathered before my first flight and tracked it every year. Maybe we can decide on what an average number is. Of course the prop will have to be the same size or we could just measure from the center of the spinner down.

David, would you elaborate on the laser part? For those of us that haven't drilled the gear .... what should we do??? Linn ________________________________ Message 23 ____________________________________ Time: 07:55:15 PM PST US From: "David McNeill" Subject: RE: RV10-List: Nose Strut / Tires I will describe the Glastar procedure. To determine the actual toe in we hung the aircraft on jacks and tail stand so that it was level a few inches off the floor. Using a plumb bob we dropped a line from the elevator of the aircraft perpendicular to the longitudinal axis of the aircraft. We also measured the distance between the outboard faces of the main wheels. At that point we shot a laser from a pencil laser taped to the outboard face of the main wheels to the line below the aft elevator edge. At that point , if toe in/out were zero we would have traced a large rectangle on the floor of the hangar. What we had was a trapezoid where the base (aft ) was 115"(?) and the top was 95"(?). By measuring the height (distance between main gear line and elevator line we could determine the angles at the base and figure the toe in/out. In our case it was toe in. IIRC the base angles were computed to be about 87 degrees which meant that the toe in was 3 degrees. Because the measurements are large , any angular error is reduced. We then (after removing the bolt) rotated the gear leg in the socket and formed a near rectangle on the hangar floor. At that point we clamp the gear legs in the sockets, and proceeded to use a pencil grinder to open the weldment in the direction of the needed adjustment. When sufficient material had been removed we used a upsized drill ream to create d a new hole for a larger bolt. -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-liste -server@matronics.com] On Behalf Of Linn Walters Sent: Wednesday, August 12, 2009 7:21 PM Subject: Re: RV10-List: Nose Strut / Tires --> David McNeill wrote: > If anyone decides to try and change the toe in give me a call.
