a The part that has the most mpact on helicopter ilying is the main blade. There are often cases when jlyirg
performance has been lmproved j!sl by replacrng the main blade. l\,4oreover there is a big diiference in ilying
performance between a hellcopter with a balance,adjusted main blade and a main blade that has not had the
balance adjusied. In cases when the helicopter js not flying well, we recommend the first ine of action is to
replace the main blade with one that has had its balance adiusted.
