This section will have a variety of manuals and data-sheets relating to electric helicopters. Wherever possible I will link through to the best online copy I have managed to find.
Any files hosted here will be documents that have been scanned, cleaned-up and converted to PDF files by me.
If you know of any links to relevant manuals or datasheets, please contact me so that I can build a definitive list. Also if any of these links become broken, please tell me.
