Spoilers and up elevator allow the wing to fly at a high angle of attack without stalling. A properly tweaked fat winged poly with a little wind can descend almost 90 degrees with full spoilers and full up elevator. It's beautiful thing to watch a poly in the hands of a master make a "helicopter" approach to a 99 landing with perfect time. I like to make a flat approach gradually adding spoilers and up elevator until about a foot high and 3 feet from the spot then let go of the elevator stick. With this method the plane runs out of energy and gently stalls on the spot. I've found a controlled stall is much more accurate and easier on the airframe than punching down elevator and dorking. ----- Original Message ----- From: "Jeff Nibler" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, February 11, 2002 5:14 PM Subject: [RCSE] How steep of an approach with RES?
