Balancing?
 
Whats the best way to add weight to a wing tip?

First, get some led weights from your LOS or use some flat washers. Lay a ball bat on your table and then lay your wing upside down over it ( just helps keep it centered ). Add weights to the high tip until the wing is level. I open up the tip, from the bottom if possible ,and add led with 5 min. epoxy, so that it doesn't come loose, right on the CG line. You can usually glue it to the last rib or tip former. Do not glue led to a plastic tip. Then just patch the hole with the " repair" covering you bought when you got your plane. Hope this helps you be "on the level". Pun intended.

Lead is lead, but are you refering to sinkers(fishing) or am I missing something. Thanks for the reply by the way.Gonna try to keep it "on the level".

Aero, your LHS probably sells self-stick lead weights in 1/4 or 1/2 ounce increments that are flat and convenient to use. But you can use any lead, or BBs or whatever works for you. Permanent attachment will depend on which type wingtips are on your plane.

But you need to balance with the aircraft fully assembled, not the wing by itself!

weights and stuff...
 
vinnie is right, make sure that everyything is installed before balancing. Things like the muffler hanging out the right side will probably effect the balance and has to be accounted for. For weights I go to a local service station that balances tires and ask for the left over balance weights. I get a whole bag full for free. Some of the weights are fairly long. Just cut differnt size pieces and test until you get the one you need. I like to use RC56 glue because it stays flexible and won't let go. Have fun, Fast! :D

What I have done is go to the local tire shop and get some old lead weights for free. A steel plate and hammer works wonders!

Thanks guys. I thought I might be on the right track. Got hammer in hand, and soon will be straight and level.

To me, he is right on!! I just hope the same guy that got in on a thread I was in once,does not see this posting! :D We went back and forth about this lateral balance thing, "wing on....OR... just the wing needs to be balanced". As I tried to explain in that thread.... Your fuse will most likely be heavy on the right side. (muffler). Why not put the wing ON and do it right? The guy made a reasonable point, being that the "leverage", for lack of a better term, is very minimal because of the close proximity of the muffler to the fuse side. He also stated this in relationship to balancing a TRAINER, which is more forgiving. BUT to me...... If that fuse is right side heavy, and you put on a perfectly balanced wing, it will not be balanced perfectly. AND WHAT'S MORE..... the word t-r-a-i-n-e-r, usually means a new person, (not always). Why "train" them half-xxxed? Sorry I went off the deep end here but memories of that thread, and the some of the mis-guided logic, got me riled again!!!:D ..lownslo

Although balancing a trainer wing by itself is certainly not going to get a nubee in trouble, i always do balance most planes assembled. The point is well taken and in the words of Roseann Addanadana................never mind.
