Maybe in Harlingen.

I changed the oil in my 231 yesterday. For the first time, I had no mess. (Actually, I lost about 3 drops, when I removed and replaced the hose to catch my sample for oil analysis). I used a dual system. First, a gallon plastic zip-lock baggie around the filter after loosening it. It is a bit of a PITA turning the filter inside the baggie, but doable. One problem with the 231 is the fact that when the filter comes off, it has to be turned in multiple directions to clear the linkage operating the cowl flaps, but the zipped up baggie does a pretty good job of that. Another problem is that when the filter is removed, the connector fitting continues to drip. This is where the second (back up) comes in. I built the attached drain channel to catch this. The channel snaps up under the transverse cowl flap rod and directs the oil the baggie didn't catch into an oil drain pan. Painful to have clean all this up, but far better than cleaning up the bottom of the firewall and nose tire. Oil Drain.doc

I think I remember seeing a report in Aviation Consumer a few years back about the various tie downs, where they measured the pulling force required to "fail" them. For anyone serious about this issue, it may well be worth the effort to dig it out.

PM returned. Bad email address?

It is on its way.

Welcome aboard.

It seems almost universal. There is a slight downgrade getting out of the hangar. I pull mine out by hand, as it is easier than hooking up the tug. But getting up that upslope putting it back in is a minor inconvenience for two people, but almost impossible for one. My tug has no problem with it. Mine moves just about as fast as two people pushing by hand.

He is using an adaptation of my original design. Mine has a 28 tooth drive gear and a 40 tooth driven gear. I do have all the plans for mine, and will gladly share. They are a little voluminous for this forum, but I can email all of them.

Yes, the LASAR visors articulate to the sides.

MBDiagMan, Look at my album for photos my tug. Now you have another reason to come see me at RBD; to look at mine in person. Don

How about details (materials, dimensions, etc., for the CBs trying to copy your design.) And how you pull the stakes up afterwards.

I had the exact same thing. Engine got rough, within about 30 minutes of takeoff. I went through the process and came to the conclusion it did not require a precautionary landing. By the time I got to my destination, I had diagnosed a partially clogged injector. Told the mechanic to check the number x injector. Thirty minutes later, he had pulled and blew it out. Problem solved. Nice to not only save a bunch of A&P charges, but really feeds the ego.

This one costs $200. A build it yourself Stratux is cheaper. Mine was only about $75, but it is single band. If you are a real CB, that is big money
