Hi Everyone, I have been flying my outback rescue since christmas and have a problem with the top blades chopping the ends off while in a perfect stable hover no wind no sudden movements just the expensive sound of breaking plastic can anyone tell me why this is happening ? bottom blades are fine. The mast has about 1/8 inch of vertical movement can't rember if it was like that new I don't no what they are hitting can't see any marks on tail boom.
It is just one blade end at a time that is missing. the mast is a bit bent only slightly though
Hope someone can help me as Iam on my 4th set of blades. thanks
