    Tandem double hang test

    No Title Hello Chuck, Am I correct on the thinking of Rotor Thrust Vector (RTV)? RTV should be ahead of Center of Gravity (CG). When the gyro is flown at top speed and the control stick is full forward, RTV should pass through or slightly ahead of CG. The red line passing through the rotor...

    Buying an ArrowCopter second hand

    Insights to flight characteristics of the Arrowcopter???? I have never seen an Arrowcopter in person. My imaginary drawn line of thrust for the Arrowcopter puts thrust above centerline. Having to apply significant forward stick at high cruise rocks my preconception of its flight...
