    Can't wait to have the Texas Toye grace the skies of North Texas!

    Gearbox Chip Detector

    I give you that there is a big difference between an engine and a gearbox. Two different environments that the detector would work in. However, like the little boy that kept hollering “Wolf”, soon his alarms were ignored. Over time, don’t all humans have a tendency to ignore false alarms?

    Gearbox Chip Detector

    Myron, I used to fly for a patrol company. They thought chip detectors would give early warning of problems and save the high cost of major repairs. Detectors were add to all their piston aircraft. After about a year they removed all of the detectors. Frequent false alarms kept the aircraft...

    Subaru EG33 passes 850 hours + video

    Speedracer, the oil dumps through one injector in a section of pipe where three cylinders are running through. About six inches later that section joins with the three cylinders from the opposite side and goes for about two feet more then exits. If I remember correctly the orifice diameter is...

    Subaru EG33 passes 850 hours + video

    Our Subaru EG33 powered Glasair recently crossed the 850 hour milestone. My wife, Rhea, had an idea to commemorate this event by making a short video. She planned a flight with maneuvers and flew her Sportsman as formation flight lead to get shots of the two aircraft executing her plan...

    Composite fuel tank question

    John, I cannot say with certainty that ethanol is the villain here. The damage in your friend’s tank looks very similar to what I have seen in other vinyIester tanks that have had ethanol in them. I suppose the only way to find out for sure is to test with all the different chemicals in your...

    Composite fuel tank question

    One more thing, I have built several fiberglass tanks for water and for oil and an intake manifold. I found to prevent pin holes, use a layer or two of the fine fiberglass cloth (the 2oz. stuff commonly found in model planes) sandwiched between the structural fibers. The 2oz cloth has a fine...

    Composite fuel tank question

    Please test products prior to using then in your fuel tank. A few months ago, the vinylester and ethanol question was asked on another group that I am a member … I wrote the below When building my Glasair I was skeptical about the ability of vinylester and foam to stand up to fuel long term. I...

    AutoPRSUs engine discussion

    I fall into Neal’s description. I did not install an auto conversion because it is less expensive. I did not install it because it is easy … if it were easy Lyc would have been out of business long ago. I prefer not to take the path of all the sheep. I love the challenge of doing what I have...

    P-51 type radiator

    Air enters the P-51 scoop under the wing area of the fuselage. This is a naturally high pressure area that helps push the air in. The air exits where the fuselage is narrowing, this should be a lower pressure area and should help pull air out. The above is one of the reasons that I decided to...

    P-51 type radiator

    Bruce, my radiator has about a 10 degree tilt. I now wish I had put it in at 90 degrees. The radiator core is 16 inches X 15 inches X 2.75 inches. With the exception of long taxing in a crosswind, I find I have too much radiator. I must warn you that building a belly scoop is far faaaaar...

    P-51 type radiator

    Pfarber, my radiator was built by Rod Davis in Arizona. Ron builds a lot of the radiators for race cars like those at Indy. He said that aircraft and racing car demands are similar in that they should have very low drag … I went with his recommendation. The radiator is a two row, single pass...

    P-51 type radiator

    Myron, the only time that my temps might go higher than normal is during long taxing with a stiff crosswind. The wind blows the prop blast away from the scoop. When I am able to point the plane into the wind the temps come down. I also found that I have too much cooling. For drag reduction...

    PSRU Oil Operating Temps

    Bruce, so as not to steal the “PSRU Oil Temps” subject, I answered your question under the subject titled “P-51 type radiator”

    P-51 type radiator

    Bruce wrote: "Hi Russell - do you have any pics of your radiator set up that you would like to post? Does it extend up into the fuselage?" Bruce, the designers of WWII were very good so I mostly copied the P-51 type scoop. About 2/3 of the radiator extends into the baggage compartment. Photo...
