These engine mounts are machined out of 6061-T6 billet stock, and will add a bit of flash to your Falcon 120.  Along with good looks, they are designed to help support the fiberglass mounting plate of your airframe. (a known weak point)  The bottom mounting holes are threaded 5mm.  Don't worry, there is plenty of flat area on top to drill, and tap holes to suite your turbine application.  To help support the fiberglass, and protect your airframe from hard landing damage, with heavy turbines... there is a 5mm hole facing forward, that will allow you to bolt into the flat at the back of the mount. 

These should also fit any of the Falcon 120 clones.  (BobCat, GoldCat, Tornado, etc)



NOTE: the top 4mm holes have been removed since they were only used with the AT-180 engine.
