Hi gang...I have a World Models 60 size Zero ARF /w saito 91 .I got this plane 2nd hand . I have a problem w/ it tipstalling on the left wing. I have balanced the plane laterally by hanging it upside down on a string . The left wing was a little heavy so I added 1/4 oz of stick-on weight to the underside of the right wing and it balanced out good.I really have to bring it in hot so as not to see the"tip monster " come out of its hiding place somewhere in the plane

Its really faster than I like to land the plane.
If I wanted to raise both ailerons to give it a washout effect, how much would you raise them OR
would you just try to raise the left aileron? If I raised just the left one , wouldnt this put the plane out of trim? THanks for any help yopu can offer!!! John
