Default RE: Heli wobbles during flight

Don't any of you know how to balance paddles and blades? Get a long hollow cf tube(30") and attatch small hooks, xmas tree bulb hooks work on smaller blades. No other way is as accurate to weigh a set of blades. With the hooks in place check the balance of the device. Next drilla smallhole in it's center point and push a xmas tree bulb hook through it. This wire will be wrapped around something solid, get creative. Now take the blades anlay themalong side each other as they lay on another rod. If one tip is heavier markit. Now weigh them on your new cf scale. One will likely be heavier, even in new blades!Now ya gotta think a little about how to change the tip weights and overall weights. Take the lighter one and spray paint on the bottom, for light adjustments, or sand the heavier onetill they match. It's great to have evenly weighted blades but having the weight in the right places has a huge effect too. If ya add all the weight to the tip and the blades spool up, that tiny bit of weight will get surprisingly large. Ya gotta get real good at balancing paddles and blades if ya fly a chopper.
