Delta Ray
There’s a plastic hatch with louvres (above left), that provides access to the receiver and the battery. The receiver (above right) is specific to the Delta Ray and the yellow arrow points to the pins for the binding plug. This was the best
position for the battery (below left) to achieve the proper CG. It happens to be right where the hand launch finger wells are molded. Black double-sided tape goes on the top of the tip mounting plate (below right).
early afternoon was huffing and puffing with 15–20 mph winds from every direction. Since this is a plane primarily for beginners the manual cautions that the plane shouldn’t be flown in winds more than 7 mph. I wanted to test all three modes and their parameters, so the flight mode switch on the Spektrum DX4e transmitter was set first to the Beginner Mode. This is recommended so that the plane will take off almost by itself when the throttle is advanced all the way. Even with the wind it worked just as adver-
tised. The SAFE and AS3X performed well, but the minimized control authority worked against control input to keep the plane from getting blown away from the field. After switching to the Intermediate mode, the added response worked somewhat better for the windy conditions.
So in the interest of keeping the plane within sight I switched to the Experienced mode which provides full control authority but with a dose of AS3X stabilization still added. The plane was really bounced around
but now the full throws made control much easier and despite its very light weight the Delta Ray handled the wind pretty well. Those in the Midwest will probably find that a comforting thought where wind is a daily given fact of life.
The bottom line to this point: follow the manual. For any beginner, fly in benign con- ditions in both the Beginner and the Inter- mediate modes. So after this first experience there were still some more test flights to try out the more stabilized flight regimes.
Some of the supplied tape goes around the leading edge of the wing/tip plate seam, and along the seam (above left). Tape also fastens the wing fence. A
58
shaped piece of double-sided tape along the root of the vertical fin (above right) holds it fast in the well on top of the fuselage. A tight fit also helps secure it.
