	Corona Blade Crutch Upgrade


	For LMH


	The Corona Blade is the lightest crutch to date. It is 3mm thick carbon fiber replacement keel for the stock Corona aluminum crutch keel. The crutch is nearly 40% stiffer and Almost 50% lighter than the stock aluminum keel.

The aluminum keel weighs 79 grams. The Blade carbon fiber keel weighs in at a feather light 40 grams.
This is not an entire airframe; it is the center keel only as well as a new aluminum canopy mount. A more compact layout with all three servos parallel. Also, the landing gear is mounted 1/4 inch further forward and 1/4 inch lower on the keel for a taller stance. The motor plate mount slots are elongated as well. This elevates Hyper Drive clearance problems found with the aluminum crutch.
It is a drop in replacement for the aluminum crutch using all of the stock hardware and for the the older wooden crutch you will just need to purchase the landing skids and motor mount from our OEM parts section.


	- Lightest and strongest frame - Direct replacement to aluminum version - Requires new motor mount and skids for older wood version - Comes with aluminum canopy mount and all hardware

	Billet Aluminum Swashplate for the Corona


	For LMH


	This swashplate is a drastic improvement over the stock part in many ways. First, it is much stiffer. The stock plastic swashplate is very flexible. This flexibility decreases cyclic response. The Billet Aluminum Swashplate eliminates this unwanted flex, adding a degree of precision unattainable with the stock

	part. second, it is more precise. Precision bearings have virtually no play what-so-ever. And third, it does not require adjustments (as the stock part does). Also, the stock swashplate is prone to wear out over time. This swashplate should have a very long life!

	tail rotor much more clearance for landing tail down or in high grass. Second, when mounted high, the tail rotor operates in "Clean" (undesturbed) air. This gives an added degree of control not found in standard straight tail designs.

The kit comes as a very complete assembly. It includes the two piece carbon fiber tail boom, two tail boom brackets, all screws needed, a complete belt drive assembly, modified tail blades, linkage belcrank and clevises, a carbon fiber horizontal tail fin, six ball bearing idlers, an open ball bearing supported tail shaft hanger, and complete instructions.
