In the last while, I have been sanding and shaping the helicopter. I did end up getting the pneumatic sander. It is the perfect tool for the job. I have probably spent 10 hours, but many more are to come. It is ver difficult to get it to the same shape of the real helicopter, it is still more square-ish then I would like it to be. Also just realized that the rear-bottom comes to a point, so a lot of material is yet to be removed. Thanks in advance for your comments.
