It will will depend on angle of attack, but in general, that area will be at a slightly lower pressure. If it is a vented cap, it would be a good idea to add a tube with the opening pointing into the oncoming air to gain a small amount of ram pressure.

While practicing a stall, during the recovery, some how the fuel sloshed in the tank and fuel came out the went tube and smeared the canopy. From that monent on I could not see clear at all. I landed with great difficulty. Afterwards I moved the vent, placing it at the high point and runnig the tubing to the bottom of the fuse so that fuel could never come back in my field of vision. At the present time I use a full size aircraft fuel cap that has an internal vent system which will only allow air to vent and not fuel. Since I now have wing tanks which are connected to the header tank, any overflow goes to the wings which each have overflows which are on the bottom of the wings. Orma L.

Mark Langford, Huntsville, >AL +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I would advise all U.S. builders to check with their individual DAR for any questions they might have on their project as far as the final inspection goes. The Reg's can be vague and subject to the interpretation of each DAR so if your DAR sees it differently, that's the way it is in your world. At least until you get another DAR and pay another fee. And Mark, that's a good price on the inspection fee. The going rate in the midwest seems to be $500. Progress report: I seem to have stopped my oil leak. It was the starter plunger. I've relocated my battery to the firewall from just behind the firewall. I now have a place to store 2 quarts of oil and some tools for cross country trips, that being in the old battery box. I got three books on test flying homebuilt aircraft from a friend and intend to get into some serious test modes soon. So far I've been mostly just having fun. 17.9 hours on the hour meter at the end of a flight on Saturday. I also have the fuel leak on the Tripacer carb fixed and need to get it back in the air. It seems quite lonely with it's tail tucked into the corner of the hangar. Have I mentioned how much I enjoy flying the KR? YEE HAA.......

While looking at type 1 and type 4 engines I noticed the cylinders on a type 4 have a bigger gap allowing better air flow but the engine overall weight is 17 lbs more then a type 1, so which engine should I invest in? I still have to pickup the KR2 and was wondering what is the height of the firewall. Thanks for any advice, I enjoyed talking with Mrs. Robinson and look forward to flying this jewel one day.
