I recently installed a S-64 Skycrane addon helicopter in FSX, and I can't seem to set any new key mappings to lower the water tank snorkels (firefighting model) or to lower the logging claw (every other model). I need to find out how to get the key commands to perform these controls.

They should be in the read-me that came with the download.
If not email the designer and ask him.

What readme? I downloaded this addon from www.simviation.com and I looked in the folder and didn't find any readmes in there. 
I think Jordon is the one that made it.
Contact him here.
