标题: [转帖]The Waterfall [打印本页] 作者: 论坛老模友 时间: 2003-2-10 06:02 标题: [转帖]The Waterfall What it is:
A continuous tail-over-nose descending flip. It's not a loop, but the aircraft actually flops around its canopy.
CAP set-up:
Once again, the critical component is having the 3D-elevator travel 4-1/2" of down elevator. An aft CG helps this the most.
How to do it:
Start relatively high. At low throttle, gradually pull the nose up until it's near vertical. Just before it stalls, add full down and full power at the same time. You have to continuously "fly" the rudder and ailerons to keep the plane flipping over in a straight line. To do consecutive Waterfalls, continue to hold full down and "fly" rudder and ailerons, and chop the throttle as the nose comes back up to vertical, then add full power as it flips straight down.
Trickiest part:
No doubt here- flying the rudder and aileron correctly. You really have to "fly" them and make constant corrections. The amount of rudder you add will vary. If you don't do this, the plane will fall off into a knife edge spin.
Recovery:
Just neutralize the elevator and the CAP will quit flipping, but expect some over-rotation, so practice high until you get the feel for it. Fly out straight and level, or stop the rotation while pointed vertical and go into a torque roll.
Worst way to mess up:
Take it down too low, over-control your elevator on recovery and snap into the ground. To avoid this, simply change rates on your elevator to normal 1" travel.
