If you look off to the side a little in the flare you can judge where you are just fine. After about my first 15 hours doing all three pointers someone asked me if I could see anything straight in front of me and after thinking about it I realized that I had no idea! I knew that I had no visibility problems that affected my landing and I just really didn't know where I was looking until I consciously paid attention on the next flight.

I used an old car air-conditioning condenser with about 3/8" lines in and out of it, you'll be surprised how much better the drier works using cool air rather than warm air!!!!!!!!!

I'm sure there's a diagram somewhere on the web, but the gist of it is: 1) drain it at the tank bottom, which I'm sure you've done (as suggested already). I leave mine cracked just enough for it to drip a drop every once in a while, just in case I forget to do it for a while. 2) run a horizontal line as far as possible from the compressor to allow moisture to condense, giving it a slight downhill tilt so the water will run to the inline "water separator" that you can get for $20 or so from Harbor Freight 3) drain it regularly 4) if you're going to paint with it, buy one of those little "one shot" desiccated plastic air filters that screw in between your paint gun and the air nipple as a last ditch filter to catch what little moisture makes it past the water separator (about $5, and worth it). My air system consists of a 12' long piece of 1" diameter PVC pipe fastened to the wall with an air filter/separator on the end, with a two way elbow and a quick disconnect on the end of that, with more pipe running vertically from there to the ceiling and to other locations in the shop. Copper would be even better, since cooling the air is the goal. At the paint booth at work we have a compressor sitting up on a wooden stand (to elevate it) and has a coiled copper cooling pipe running out and down to the quick disconnect (it looks like a moonshine still). There's a little fan blowing on it to cool it off, and a water trap/separator/filter to catch the water. Obviously set up by engineers, but you get the point...

So maybe I could help. Sounds like your compressor is probably OK. Overhauling it will not solve anything unless its knocking, using oil or the capacity is down. Condensate is a problem that has to be dealt with in any compressed air system. The only real way to get rid of it is thru use of either a refrigerated dryer or a desiccant dryer. Short of investing a substantial amount of money, the easiest way to get a reasonable air quality is to install a drip leg on the tank outlet, with a drain, drain the receiver often (several times a day) and install an inline coalescing filter. The amount of condensate depends on relative humidity, volume of air compressed, pressure in the receiver, and radiant cooling of the receiver. The problem is that ambient air at x relative humidity becomes compressed air at 10x relative humidity when compressed to 150 psi, it then quickly condenses to the saturation point still leaving 100% RH inside the receiver (lots of vapor) It's fairly easy to get rid of the liquid, water vapor may be a problem, as it condenses in hoses, and out of tools, nozzles, etc., as the air re-expands to atmospheric pressure. Keep your air tools well oiled, they will probably be OK. Just a little water or oil could ruin a paint job. I may be able to find a good used filter and automatic tank drain at work that I could send to you. I deal with these kind of problems on a daily basis, but it's sometimes hard to justify a big outlay of cash for a unit you use at home. email me off the list if you have any other concerns or if you want me to try to find those items for you.

Home Depot and most paint stores can sell you a moisture trap. It should be placed as close as possible to the gun. Draining the tank can help, but it is not fool proof and the longer you spray the greater the probability that you will get moisture in the paint. In humid climates, even a long hose can cause problems if you don't trap the moisture right before the gun.
