I have tried heating the fiberglass with a hairdryer as suggested by zenith, hell, i even tried (carefully) using a propane torch....(shudder). I also tried replacing the A4 with an A5 to see if that would narrow the gap, all to no avail. so my question is; do I leave it, fill it in and paint or does anyone have any other suggestions. 2) any ideas how to ground the position light? I was simply going to run a short piece of wire from the inside of the light socket (housing) via a ring connector and an A4 rivet and connect it to the aiframe with a second piece of wire. Any other suggestions?

Make sure you sand off the point where your ground wire will attach to the airframe (to remove any oxide coating) and use an anti-oxidation compound on this termination. A product called "No-Ox" is available for use on aluminum to copper electrical connections. Anti-sieze might work as well. > > > 2) any ideas how to ground the position light?

The aircraft nose is pointed down as the plane is inverted and he finishes the roll about 90 degrees off his initial heading. I also wonder how many Gs he pulled to get the nose level at the end of his roll. It is hard to estimate his altitude, but how many mistakes high he was flying? The 701 is a tough little plane but the wing is probably not the best for inverted flight. It takes a significant push on the stick in a Decathlon or Pitts to keep the nose up while inverted with their symmetric wing, must take a massive push with the 701.

I have been told (by someone that has looked at one carefully)that a simple increase in span OUTBOARD the struts was done with NO change to the web,caps,skins, ribs ect.,just the addition of one extra bay.

However, forward-thinking homebuilders have choices. Your choice of an H-D is a great example: H-D chose to improve thier design with modern materials, efficient manufacturing methods, and performance innovations over the years, and Lycoming chose not to. So, to compliment these changes, I only use semi-synthetic motorcycle oil in MY Evo-powered TourGlide and not the SAE 60 straight-weight as recommended for the Knucklehead. I am thinking VERY strongly in installing a Twin-Cam in my 601XL - I just hope the engine proves itself in homebuilts. You are an inspiration to us that are not quite there yet.

All kidding aside, the photo-grey process comes under many trade names, some cost more than others. Frames depending on the maker and construction will vary in price as well. The prescription of the lens may complicate the fabrication to some degree and price will vary. Now from just a "I got this quote for eyeglasses" and making judgments about comparison shopping without all of the details of frame, lens composition, prescription and so-forth is an exercise in comparing apples to whatever. In Macy's they have frames on the shelves over $400 without the lenses. I'm sure if I asked my wife for some top prices, she could come up with higher numbers than that. Now, if the prescription calls for a special lens with a drastic correction, and you have top of the line designer name frames with flex-on or titanium, a progressive no-line bifocal process, antireflective coatings, etc. that quote may not be so far fetched. If you have a common low correction simple line bifocal, no name plastic frames and Billy-bobs photo-grey, then go shop your prescription. Make sure you compare apples to apples and know what they are totaling up on the ticket for add-ons. Take a close look at the cost of the frame by itself. Does it's construction warrant the price? How about your lenses, are there add-ons in addition to the transitions(transitions is a trade name process and costs more) like coating, a high refractive composition (usually recommended with extreme corrections to keep weight down) and others. Read the quote completely, if there are items included you didn't ask for, have those things explained to you or removed from the lab order and get the price under control. There are shops that will take you for a ride, especially small independent practices or practices in high rent real estate. My pilot glasses are the Scheyden flip-ups. the sun lens is a separate piece hinged to the frame. http://www.scheyden.com/lo/aviation.html I like the fact that I can instantly go from normal to dark in a touch of the finger. They are very well made, but not cheap. I have a progressive bifocal now, but next prescription exam I will switch to a line bifocal, because the progressives have such a narrow "near" optical zone, you are forced to turn your head and look directly at whatever you need to see. Not so convenient in the cockpit.

Most people choose straight mineral oil for break-in followed by ashless dispersant oil once oil consumption stabilizes. The use of 100% synthetic oil has proven less than successful in aircraft applications inasmuch as it fails to properly deal with the combustion byproducts that enter the oil. Your multigrade aviation oils are typically a semi-synthetic. The better oils have additives that are designed to inhibit corrosion and reduce wear. The former is especially important in engines that are not run frequently. We had a guy at our local airport ruin his engine by running el-cheapo automotive oil in it. He had an engine worth $10k or better and complained about putting $4 /qt aviation oil in it when he could get auto oil at K-Mart for a buck a quart. When it started showing metal at 200 hours he found that his cost savings was an illusion.

For everything else, including differentials mineral lube. If you aren't flying a couple of hours every day don't even consider Synthetic oils.

Ford has used the same axel in the Crown Vic type cars for almost ever. In the mid 90s, one year they changed to synthetic lube in the differentials, no other change. All of a sudden they had lots of trouble with differential bearings and sometimes in trying to remove the bearings for replacement, the case was ruined because the bearings were frozen (rusted) in so bad that they could not be removed. Seams that pure synthetic oil has no coating action to prevent rust when not in use.

Except it is a fact that one should use a non-synthetic oil for the break in period. The reason is simple, regular oil is not as friction proof as synthetic so the engine's rings will seat quicker. My RevTech owner's manual says to use a regular 10/30 for the first 10 hours and then switch to their (naturally) synthetic oil. It's been my experience that engines will still break in with synthetic oil, it just takes longer. I put Mobil1 in my Harley and Subaru's from the get go. My last Subaru powered gyro now has 800+ hours and running strong. I do agree to use a very good oil whatever the brand and stay away from K-Mart specials. .. An added note, I saw in my Harley service manual, I don't have the exact words but it said that in the event you didn't have Harley oil you should make sure whatever oil you use should be rated for diesel engines. I will try and find the exact paragraph and post it if anyone is interested. The only reason I can think of is that Harley's run a lot hotter than other engines. The book says the operating temp is 240 degrees. The Harley shop told me 250 is not unusual. Larry N1345L, www.skyhawg.com.
