The installation should be similar for the Kitfox with the probe mounted on the side of the tank. Because of the dihedral in the wing of the RV4 we bent the tube down at root and up at the end of the tube. We used o-rings under the hold down bolts with a countersink cut in the plastic top of the probe. Red Loctite sealant was applied to the gaskets and the hold down bolts. To test the integrity of the tank, we sealed all of the openings and used a balloon over the fuel outlet. We then applied enough air pressure to expand the balloon and let it sit for 24 hours. The balloon should remain expanded otherwise there is a leak which must be repaired. Hope this helps.

LOL! I wondered about that when I was testing. Needless to say I didn't push it. However I don't think there's any worry. The prop will always spin faster pulling than pushing, since slippage works against you both ways. (Meaning, it slips when generating thrust, and slips worse when being thrust because of the lousy airfoil.)

Maybe you can do the math for RPM, pitch and speed to get an idea of RPMs with the slippage being a safety factor.

Adjust the shutters as needed to keep temps above 140 degrees. They work like a charm. They also help get the temps up faster on the ground. An easy, inexpensive mod that I highly recommend, whether or not you have the RK400 installed. http://highwingllc.com/ John Alexander wrote: This certainly makes sense, since the RK-400 clutch is set to disengage at about 2500 rpm. I'm guessing that with older ones, the springs that hold the slipper shoes back at low rpm get tired and so engage and disengage at lower rpm. But yes, as long as the engine rpm is below the engagement rpm for the clutch, the prop will go to town - spinning freely. Please do take note of my aside on warming the engine with the clutch installed. I repair more than a few cold seizured engines every year. This is something that is completely avoidable, but becomes something to always keep in mind when using the RK-400 clutch, since the engine can operate at very low rpm and load factors. Long, low power descents followed by a go-around is where you will get bit here.

Most of those probes can be cut down in length to fit your application. You could to run it at an angle, like from the outboard top of the tank to the inboard bottom. This angle would allow a longer probe and be more accurate. A threaded boss could be glassed into the tank and the probe threads into that but you would have to have a way to remove the probe after the wing is finished, for maintanence. Although it would be cool to do that and I thought about it myself since I installed a Dynon D-180 but I just went with the sight guages. It is not hard to do if you have some fiberglass experience.

The only difference that I see in the H.F. HVLP and regular is that the HVLP has a larger fluid tip to allow more liquid to flow and the aircap doesn't atomize the paint as well. They are both gravity feed guns which to me is the only way to go. I sprayed Aerothane on my plane and I found it incredibly easy to spray. I did add a little more reducer than called for, seemed to atomize a little better. My first coat was a light tack coat followed by a full wet cross coat and then one more cross coat that was very wet. As someone mentioned ealier, it is very important to spray a test pattern before each coat. I do it on a cardboard box that I have sitting next to my paint job. I normally spray with the trigger wide open and control the amount of paint going onto the surface by the speed of my arm, always maintaining a consistant speed, distance from the painted surface and always have the gun 90 degrees to the surface the entire time the trigger is pulled. Also, start spraying a few inchs away from the part as you begin moving the gun toward the part to paint. You never want to start pulling the trigger with the gun pointed at the part. The more lights you can have the better. You have to see the painted surface in the reflection of the light to see how wet or dry the paint application is. I usually run about 60-65 PSI at the regulator which is at the other end of my 50 foot hose, the pressure will drop a little before it gets to the gun.
