    Tandem gyro plans

    lathe advise

    The thing that you need to consider is that the lathe is the cheapest part of your purchase. I have spent twice as much on tools than the lathe.

    Tandem gyro plans

    I've spent the last weekend cleaning and modifying my gearboxes. The modifications were changing the air vents by 90* and changing the fill cap into a sight glass. I was also trying to determine the amount of force required to turn the shaft. It measured 15 pounds but I have little...

    Tandem gyro plans

    I received two Honda GL 1800 gearboxes yesterday by UPS. These will be modified to be used on my tandem project. The gearboxes will be coupled and mounted on a trailer to test their durability. I will start posting pictures as soon as there is something to see.

    So 12% is a pretty fine frog! A 13% frog is not so fine. Well, I guess, I'll go get me some kick-a-poo-joy juice!

    kicking a dead horse

    I have following this thread with great interest. From my reading, there is a constant reference to a term "fineness". Doesn't this refer to a rotor blade smoothness and improved performance?

    Tandem gyro plans

    Don, You had recommended that a solution to my gearbox problem may the use of a Honda final drive differential. I have been looking at a GL1800 differential but I have a question about the lubrication. Since it will run on it's side, what changes would I need to make to insure good...

    Gyrocopter-Military Aircraft Encounters

    Erik, The F5E&F are both two seaters as is the T38 trainer. There are some differences between the two like the F5 has a longer nose for radar and guns. The F5 in the picture is a Spanish aircraft from their fighter lead-in school.

    Taiwan plane crash - unreal dash cam caught it
