----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----Thanks Lynn and Bill.. I will do all that you have suggested ..
I tested it on Monday and flew for about an hour. On the ground I did the usual preflight plus the special emphasis on checking all of the nuts and bolts , new baffles, elevator travel and hold down bolts . The elevators were removed to install a new aluminum saddle for the elevator. They installed or added a new piece of wire to the trim at that time. I am assuming that they used the right lubricant there. I noticed that up trim started about in the middle of the trim throw and it leveled off very slowly as I moved it foreword but not enough travel to get any down trim. I'm sure I can resolve that. The static and idle power positions seemed to check out fine. Had a little problem checking out the idle at first. He had a problem with the idle cut off ( much the same as was mentioned here a few days ago). I told him that we Ercoupers with the Stromberg carb have no idle cut-off.
It tracked slightly to the left on taxi and I told him to adjust the steering collar a turn or two and then it tracked perfectly straight. The front wheel registered no air pressure at all and we put 23 lbs in. My Ercoupe requires 23 lbs to keep from shimmying on landing.
I followed Bill Bane's advice and checked the new baffling with a flashlight at night and no leaks. J.A really did a super job. Itdid take 8 months though.
The engine had a different sound to it and it did sound new. Take off run was very short with the climb prop (brand new 7148) and I reached 60 in no time. The biggest surprise was the air speed. I never could cruise past 94 at 2450 rpm. Believe it or not, I reached 105 for the first time in my life. G nN, the overhaulers, said that when they measured the power at the plant, it came in at 110 %. I don't exactly what that means but they said that it would just give a mite more horsepower. Another thing has changed. At cruise power the left aileron was always slightly lower than the fuse stub. If I tried to line it up, I would be in a left turn. Now it aligns up perfectly. I flew to an airport 40 miles away and made a decent landing. I stuck around for a while and the wind had shifted to not quit 22 miles crosswind at 70 degrees. Always apprehensive on first flights, I kept the nose on the line and of course the wing came up but I was at 60 MPH so fast that it didn't matter. Oil temp, pressure, Cylinder head temp. egt was fine.
During refueling they noticed some oil seeping out of the cowl and looked like it came from the front of the airplane. We cleaned it up and I flew back to DuPage where they found an oil leak at a pushrod. So once again the prop, cowl and nosebowl are off while they repair it.
All in all, even with the problems, I am satisfied that it will be a great Coupe. Friday I will try again and I will report.
Hopefully it will be a lot shorter than this.... I will be at the Nats for sure...Dennis and I already have a room reserved.
Thanks again,
Bill Coons

You problem sounds like the typical one where the wire needs lubrication in the stabilizer area. I have seen several like this after a time of limited flying. The normal trim, especially on a 415-D model has almost no up movement of the trim tab. I would have to check the books, but I believe it is only 10 degrees. I have found that as long as the CG is in normal limits, lubrication of the casing in the stabilizer often cures the problem. You can try to make this happen by removing the tail cone and squirting (spraying liberally) WD-40 or some other type of penetrating oil up onto the casing of the trim wire. Let it set a few minutes and then do it again and again. This usually frees up the trim wire movement and lets you get those few degrees of up trim which will give you the nose down you are looking for.How is the new engine performing?Lynn============================================================================== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers/
