    How Hot Is Too Hot?

    If you suspect a head gasket leak, Napa Auto Parts sells an excellent combustion gas detection kit that is easy to use. The kit looks for combustion gasses in the coolant water. I have used this kit several times before and you have your results in less than 30 seconds...

    Does your auto-conversion airplane have over 500 hrs TT?

    To answer the question of the topic … I currently have 883 hours on our six cylinder Subaru EG33 powered Glasair 1 RG. This plane has not always been pampered. We have run in 22 air races and are undefeated in our class. She also holds the class speed record, with an average speed of 227.33...

    Successful Auto Conversion Trials, Tribulations and Tips

    Charlie, I am not sure if this is what you are asking for ... if not let me know. The inlet is about 13% of the radiator area. My reducing sleeve brings the inlet area down to about 11%. The outlet varies from about 4 to 25% of the radiator area,

    Successful Auto Conversion Trials, Tribulations and Tips

    Toolbuilder & Slociviccoupe; I have inserted a few photos to give you a better idea of what I have … pardon me if I have already posted these. All my sketches during construction have long ago been thrown away. The scoop is for water cooling only, the air inlet is approximately 10.5” wide x...

    Successful Auto Conversion Trials, Tribulations and Tips

    Pfarber, your calculations for a 200 HP radiator match fairly closely with the one flying in my Glasair / Subaru EG33. My rad is 16” x 15” x 2.75”. However, I find that in my case, your 30% inlet size is too large. My opening is about 33 sq/in …. In fact when we race this plane or during the...

    Composite intake manifold

    I made a foam mold that was a bit undersized of the desired finished size. I then coated the mold with about 1/8 inch of “Liteweight Spackling”. S-Glass and West System epoxy was uses to cover the entire mold. After curing everything was dunked in a tub of water overnight. The dunking...

    Race 84 is Back!

    I have a Marcotte. It has not been 100% trouble free … about 1 ½ years ago I replaced the output shaft and ring gear because I was starting to have spline wear. I did not know that Marcotte had a website. He is sometimes slow to reply to emails … sometimes as much as three weeks.

    Race 84 is Back!

    I spoke with Guy Marcotte about nine months ago ... it sounded as if he is still making his gearbox but in limited numbers. Ray was Guy's machinist and passed away several years ago, I think that was when production slowed down.

    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...
