My Posts This: Topic Forum | Piro LoopLearning the piro loop helped me, more than anything else, to be able to do decent piro flips, piro funels, and piro 8s.
It is hard, for me, to teach someone how to do these moves with words so it might be easier to find a video with stick movements so you can see with your own eyes. I know it would be easier for me. In any event, here goes.
In any piro move, if you want to impart a constant input on the rotor disk in a givin direction(like you would in a loop, you pull back) you want to match the rate of the cyclic stir to the rate of the piro(for every 360 piro of helicopter you should do a 360 degree stir of cyclic stick). The loop for me is the easiest way to see this clearly.
when you piro counter clockwise, you stir the cyclic clockwise and vice versa.
So im just going to give an example of a right side up, foward flight loop with one counter-clockwise piro during the loop. Start with back elevator and keep constant left rudder throught the loop, Instantly start your cyclic stir clockwise when you add rudder. when the helicopter is 1/4 finished with the loop the helicopter should have done 1/4 piro and you should now have the cyclic stick to the left. and it keeps going like that. when the helicopter is at the top of the look you should be flying backwards and inverted and pushing foward on the cyclic. when it is 3/4 through the look, the heli should have done 3/4 piro and the cyclic should be to the right. when the loop is over you let off the rudder input and the heli is flying foward.
and obviously you have to manage the collective just as you would in any other loop. a lot, then a little, then a lot.
hope this helped... probly didn't, but hope it did. |
