    Holy Cow! Giant Model Airplanes

    Example of what size my models in the 50-60's look like, and this was an average large model follow by the 21 century models: Duh, I thought a model airplane was usually sized to fit in a car and that went for gliders too. Since I don't have access to a wind tunnel, I plan on constructing a...

    MH170 and aircraft tracking on oceanatic flights

    As a radar repairman in the 1960's we all knew tracking over water is a hit and miss affair. Water vapor and air temperatures frequently did weird things to the radar pulses, ditto for shortwave radio. I'm totally confounded that commercial aircraft engines/aircraft systems are monitored via...

    Finally the ultimate light weight and almost free aircraft covering

    One of my vices is Blue Bell French Vanilla ice cream, a man has to have at least one sin.

    Comparing Thrust in Fluids and Current terminalogy [beam Billski & me up Scotty]

    To say these ratings are way over my knowledge is a gross understatement but, I know there are some who with a few clicks of their keyboard can answer this questions. "If a jet ski engine is rated at 310HP PS >2HP/LB and produces 1890Lbs of water thrust is there a way to convert water thrust...

    Take Measurements of Drawings and Much More

    This may help the CAD challenged, estimate weights plus requirements of various structures. Since many aircraft are tapered or rounded measuring each member can be very time consuming. ¼” for ribs on a tapering wing each is different, 1” longerons for fuselage trusses, tapered braces, and...

    2 Stroke Needle Bearings

    Most 2 stroke engines connecting rods have caged needle bearings CNB, on some Rotax engines the piston wrist pin are full fill bearings FFB. Normally FFB bearings cause verbal praise spoken during disassemble scattering everywhere. If CNB remain intact they are simple to install and remove as a...

    V8 Two Stroke With Expansion Cambers

    Someone is one heck of a welder to look at this engine setup. It seems to be almost vibration free except for counter torque when throttled. If someone could do something similar in a small plane the performance would be incredible. It would need one tough PRSU to reduce speed to tap all the...
