i have 2 md500 art-tech junk.the bodies are nice but a pain in the butt when you have issues.i personaly prefer the plain ole nose canopies.easy on and off.i have the walkera metal 60 walkera metal 5#10 blade 400,exceed eagle 50 with the walkera 22e metal head(which is a really crappy heli)and just got the walkera 52 micro boy that sucker is hard to fly.maybe if i could figure out how to set up the controller it maybe easier.and then my trusty double hores 9081.anyway what was i saying ,oh yea a full bodied heli is a pain to work on
