Quest X-15 Model in Blue Paint Scheme

As can be seen here, Quest's new version of the X-15 added about 3 inches to the length of the body tube, but the balsa strakes on either side of the body are not lengthened to match. The added length moves the center of gravity forward, past the center of pressure, making this model more stable. I did not have to add any noseweight to get this model to pass the string-stability test with a C6-5 motor shoved up the back.
