I don't know who told you to balance the wings... but they are very smart.

Balancing the AC laterally is just as important as placing the CG, it will make the AC much easier to fly and trim.

I prefer to balance the AC before the covering is on - that way any weight that is added can be 'Hidden' under the covering. It also makes for a much nicer looking plane...

Make sure all components are in place (Engine, rudder, ailerons MUFFLER etc).

Then hang the AC from the ceiling by a fine rope around the prop shaft and one to the tail. Centre the rope and let gravity go to work... []

Balance the plane by adding small weights to the light wing tip (Start with pennies) Once the balance has been worked out secure the weight to the wing and cover / recover the wing

Thank you so very much, no one i know of at the two fields i belong to balance there wings, i read a report that told me that more of less what you said and it makes your plane so much better to fly in all aspects, so i decieded to ask some one for help on RCU and i knew that it would not take long to get an answer, i just was not sure how it was done, the string on the rear of the plane, is it ok to tie it in front of the horizonal stabs, thank you so much for your important advise as i feel every advantage to making a plane fly better can only be good to the pilots ability to fly and also the way the plane flies and handles, thanks.

To balance a plane laterally I first adjust equipment, such as battery, receiver to one side of fuselage. I prefer to lighten the heavy side long before I add weight to light side.

Thanks again, i am one by one going to balance all of my airplanes and the next one i build i will do it from the start, i have always paid to have my planes built and it cost almost as much to buy the plane itself, i now am learning to build my own and doing ok and have many friends that help me to learn the few things i have trouble with, thanks again for the geat advise.

Where you tie it to, is not that important as long as the knot is centred and the plane is free to pivot (laterally)

Good Luck.

If you have twp people, just have one person hold the spinner while you lift the plane with one finger under the tail

I like to life it 2 or 3 times to be sure it falls the same way each time.

Once you get to the point where it falls off in either direction, you're there

Laterally balancing while building is important. But don't forget to complete the job with flight testing.

Trim for straight and level flight, then roll the plane inverted. If the roll is still trimmed correctly, you've got it balanced. But usually it will roll a little one way or the other. If the plane rolls left, then the right wing is a little heavier. Add weight to the left wing tip and try again. I use small chips of stick on lead under the wing tip.
