I find that when it has fuel in it useally helps with those sort of problems
Have you tried the trusty old Ctrl + E?
I will amaze you Ralphy, It indeed has fuel in it, but Ctrl + E has no effect on this particular helicopter, it seems to be coded in a very different way unlike anything I ever seen
I have seen youtube videos of the helicopter starting up as you follow the video but I tried the "manual" starting proceudre and all i get is the turbines whineing up and the sound that proppeler is moving then as it gets higher it just loops back to the beggnining, it's like it dosen't have fuel
