RE: Need advice on doing the Harrier
Ken 4:
Hay there!! Ok, first ballance your bird well in the longitudinal direction. Do not use the motor as a ballancing point as it is offset for thrust in most cases. Check the rear limits of the CG and be sure you are in the ballpark there. I start out almost streight and nose up directly into the wind. Back off the throttle as you add elevator. If the bird will not hold a nose up attitude, move the CG back some more. Once there in the correct up attitude and the wings start to rock, use the ruddder only to get the bird directly into the wind. The wings should stop rocking. After a few adttempts, you should get things in the ball park and learn to get in front of the wing rock with your ailerons once the speed and nose is in the correct position. If the bird is ballanced correctly and is truly a 3D bird, you should be able to fly into a nose up stall, and come down in the correct attatidude with elevator full up, no power and not much travel forward. Keep her into the wind with rudder only. If you use ailerons, your usually going to just add to the rock. Once you are into things, you will be able to stop the occasional rocking. You may be trying to hold the nose up to much, try adjusting this attitude. If you continue having problems, have a good 3D pilot fly it and see if he has problems. If a good pilot has a problem, chances are you screwed up in constrction and have the wing and elevator out of allignment. Have you sealed your hinge gaps in the elev. and ailerons? Start doing this on all your birds, if nothing else it helps to keep flutter out. Let us know how you are doing!!!! ENJOY
