The cleaner flushes out the grit & oil and <BR>evaporates completely away in less than a minute. I've been using it <BR>for a couple of years now with no ill effect on the fittings or the <BR>paint/monokote next to it that usually gets caught in the crossfire. <BR>I also use it to clean the tailwheel assembly. It's inexpensive and <BR>it works great.<BR><BR>Jerry<BR><BR><BR>>Thanks Troy.<BR>><BR>>As to the hot pink clevises, that seems like an awful lot of work to <BR>>avoid pink clevises, but at least you're man enough to admit why you <BR>>don't use the 2.5mm ones and don't justify it using some technical <BR>>excuse :-)<BR>><BR>>BTW, do you ever have any trouble with the exposed ball bearings at <BR>>the rear of the plane on the clevises? One concern I've heard is <BR>>that dirt and exhaust oil may get into the bearings on the tail, <BR>>that seems like a good point. For that matter, the MK bell crank <BR>>also has ball bearings that are exposed on the outside of the plane.<BR>><BR>>Keith<BR>><BR>>----- Original Message -----<BR>>From: <mailto:troy_newman@msn.com>Troy Newman<BR>>To: <mailto:discussion@nsrca.org>discussion<BR>>Sent: Wednesday, January 08, 2003 12:08 AM<BR>>Subject: Re: MK control horns<BR>><BR>>I use the Med ones on both elevator and Ailerons.......I have tried <BR>>the large and they stick out a bit but are better for the control <BR>>and centering of the servo as the moment arm is helped being longer <BR>>on the control surface......I find the Med ones work great....<BR>><BR>><BR>>I also use the 2mm Clevis links, and drill and tap them out for <BR>>4-40.
