RE: Walkera 60B issues
Which radio do you have, is it the FM or the 2.4Ghz. I've had a 60 and give alot of advice on them and while I'll admit some of the electronics on the walkeras aren't the greatest there are plenty of guys out there flying them with no upgrades at all.
If you want to give some more information about what problems you are having I'm sure I could guide you to getting it in the air with the stock electronics.
But if it's only the upgrading you are interested in I'd have to ask what you are wanting to change as well as what price range you are interested in staying within?
