Most people use 3/32 for KRs and it is more than adequate.

The reason is I have damaged one of them while removing the WAFs. Now, the current cables are stainless steel, 2mm diameter (that is 0.07 inch), and I suspect the local airworthiness authorities are not going to like that cable size. So, I checked the literature about control cables. Could not find anything in the construction manual, so I checked Tony Bingelis. He says standard size for all control cables, no matter for which aircraft they are, are 3.2mm (1/8"). Now, that is a surprise. I thought the cable size would be adjusted to the aircraft specifics somehow. So, should I go for 1/8", then?

Heath - Columbia, SC +++++++++++++++++++++++++++++++++++++++++++++++++++ I have a very small faring on the outside (wheel side )of the leg only. My faring is glassed to the underside of the wing and I used tape to keep it from bonding to the leg. The paint however formed a bit of a bond and I noticed on the annual last week that I have a hairline crack at the wing/fairing attach point. It may just be a crack in the paint as I didn't go into it any further. I don't consider it to be "life-threatning". If it is indeed a crack in the glass it would be where the fairing comes off the wing surface. I've really only had one hard landing in the several hundred landings to date and that was the first one.

We have the 1/4" ply for structure and the "fiber frax" for flame barrier, so the stainless can be rather thin and light. In the case of the KR the stainless is just there to protect your fiber frax from damage. I don't know what thicknesses the galvanized comes in but I've never seen anything as light as say .007.

In my tanks the fuel pick up tube is in the lowest point of the tank. That point is the rear inboard corner. Yes a finger strainer is highly recommended. The pick up tube runs parallel to the tank bottom with the finger strainer laying on its side and held to the tank bottom with Pro Seal. The fuel line then gradually slopes upward towards the front of the tank and exits the tank at the forward inboard side.I have 98% usable fuel.

The FAA closed the runway 10 minutes before both Richards and I arrived at Corona and wouldn't allow us to depart even though we had enough runway left. By noon there was about 14' of water in my hangar. My Long EZ and a number of tools, parts, etc. are well under water now, including most of my Corvair stuff. The water wasn't supposed to get this deep. Rich and Rich may have lost the Tailwind in their hangar as well. We moved my roll-a-way, compressor, and welder to their hangar after being advised the water wouldn't get that far. Those, I'm sure are a total loss now as well. We were now told the water level was still rising and would completely flood the airport and all aircraft had to be moved. Most were being towed of pushed to some of the city roads and parked for the duration. It is quite a sight seeing 100 aiplanes blocking a number of city streets. To top off the day, while my plane was being moved, half of the elevator was ripped off. It looks like I won't be flying any time in the near future.

The stick forces are so light that you could take off with the trim full up or down and not really notice, although I recommend checking at preflight and I would also use a manual cable operated trim in the KR. I also don't think that the slipstream direction is going to make any difference and you could install the tab on either side. My first KR with a VW had it on the left side. The one I have now with a VW has it on the right side. Of course your average tin cans need a position indicator of some sorts. We lost a 210 here about a month ago because the pilot forgot to reset the trim after landing and filling up with a bunch of skydivers. It came way nose up and stalled right after takeoff. One of the survivors said he saw the pilot frantically spinning the trim wheel to try to get the nose down.
