![]() ![]() ![]() Am thinking of the EZ balancer though it is not cheap. I built a Vanessa rig but that isn't always very easy to use either. And everytime you adjust the battery you have to recheck and then it falls off again. The arm's rulers and metal post to set the distance from the leading edge, don't always produce an accurate measurement since they are often not level depending on the shape of the wing surface. In theory, it should work easily with the measuring arms. Then go back around to the first and recheck. You have to look at one side at a time to see if the foam pad is at the CG point and then go to the other side to put that side at the CG point. I mark the suggested CG point and then put the plane on the balancer. ![]() The planes are forever slipping off and it gets extremely frustrating. My experience is that it is hard to get the plane to stay on those small foam pads. I have been using the Great PLanes balancer and I have to say I don't care for it much. It's never seen a balancer except for my 2 index fingers. For more normal flight, it goes back forward. For better hovering, the battery moves back a couple of INCHES. They don't seem to need to be balanced too precisely. Using a machine is cumbersome and needless. Those at my field have been known to shift the battery fore and aft not just mm but many, many mm and sometimes inches. Several mm either way doesn't matter to them. Some flyers prefer their 3D planes one way over the other. The more tail heavy, the better the prop hang. That's where the Vanessa CG rig works better, since it doesn't have the model tipping over the balance point.As I understand it, most 3D planes are balanced very tail heavy (so they get into and stay in a prop hang easily). One aircraft type that is difficult to balance with any of those machines is a 3D type, or any other which has the vertical center of gravity about even with the center of the wing inverted or not, the weight is above the resting place on the wing, making the balance unstable. ![]()
