My helis are very well behaved. I tell them to crash and they do it right away. They crash so much that I have created a [link=http://www.rccrashers.com]website[/link] just for that. One thing that I found is that the hover setting that I have in my helicopter are not the same that anybody else will use. Everytime that I lend the heli to one of my friends they adjust the trims. then when I get the heli back I have to adjust it againg. Does anyone has the same problem?
