Status: offline 		when i throttle up the skylark the tail motor will spin to much and makes it turn i put full trim against it but it still turns a bit what can i do to fix this problem does anyone know? and when i try to hover with my training gear on the ends of the training gear will vibrate alot and the helicopter goes out of control,but wont shake when i take them of. how do i get rid of the vibration without getting rid of the training gear. Thanks

Status: offline 		The tail rotor action you talk about is part of the mixer setup they use, at each turning on of the battery, it receives a signal to know where zero is for the throttle and the tail motor, you must set it to the trim centers on the ruddr and down on the throttle each time before turning on the battery.
1. If the heli is turning left or right, with the battery off move the "setup" on the gyro counter-clockwise to correct for too much to the right or clockwise to correct for too much left. Then power up the battery, wait for the light and then try again..once you get this right it holds very well keeping the heli straight, unless something pushes it that way or this, ie. light wind or if in the house sometimes the rotor wash from objects you fly close to.

Status: offline 		hay thrustline i have another question for you, when i fly my skylark it always starts to wobble alot and it doesnt matter how high it is. i have tried balancing it and it would still wobble. and do you know if it would wobble if it had training gear on, would that afect it and if not what can i do to fix it. Thanks.

Status: offline 		Two things on the skylark.
One that makes it wobble is the swashplate, watch it as it turns, it should stay smooth and not go up and down. I fixed this by taking a small piece of shrink tubing and cutting it to fit the void that is betwen the swash and the top of the frame rotor post, you must cut it absolutely straight, it may take a few trys to get it perfect, but this makes a wonderful improvement, after I did this mine hovers in place like a larger helicopter, it really settles it down, also securing the servos so there is no play in them, they should be snug and not able to move up and down or side to side, I used dbl sided tape and then small tie wraps to secure each one. After this is done, then you can balance the rotor blades, anything you do before the swashplate means nothing to these tiny birds, they will walk all over the place and you will constantly chase the sticks. There are several other things to check, but do these first.
1. Rotor blades must be snug, but free enough to move by the centrifial force applied to them to neutral them.
2. The paddles must be absolutely perpindicular to the ground.
Do this after the swashplate fix, the movement is another cause for the unstable flight and hard to hover.
3.. Get to this point and Talk again....

Have Fun!!!

Status: offline 		hay thrustline I'm talking again is shrink tubing that little piece that comes with the skylark or is it something Else that you have to get. Thanks again for your time.

Try parallel not "perpendicular" and the reference is not the ground plane (unless your LG is parallel to the swashplate at neutral - not likely)..........the flybar paddles should be parallel to the swashplate.

Status: offline 		Balancing the main Blades is not too bad, there are many methods, I used the method that Lite machines suggests, with the control arms disconnected set the heli where they won't hit any thing, add 1" stripe of trim tape to the ends of the rotor blades, leave them overhanging on each side. Then lightly tap the tip of one blade and wait until it stops swinging, if it stops horizonatlly they are okay, if one is lower add trim small amount of the trim tape to the end of the heavier rotor blade and try again. Once it is staying horizontal when it stops, press the trim tape in firmly in place, on these little ones I used 1/2" instead of 1"

Status: offline 		Oh, the shrink tubing you will have to get, they sale it at Radio shack and Home depot etc..Get some that are close to the size of the shaft, I think it was 1/4" and it only has to shrink a tiny bit.

Status: offline 		i still don't get the main blade part because they can move so how can you get them to balance horizontally if they can rotate in place. and when i power up the main gear thing that is connected to the main blades will wobble to is this a problem? Thanks.

Status: offline 		You need to tighten them up so they don't move freely, but not so tight they don't move, the idea is so the line up as the rotor turns, if they are too loose it will wobble.

Status: offline 		hay thrustline i have a problem with my rudder it has to much power and the trim wont fix it. so when looking at the skylark from the left side there are the 2 dials to twist to counter act this. which one is the right one to twist the one closer to the front or the one closer to the back. Thanks, skylark_man
