	LMH - The most durable Heli in the world . . .


	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


	Enlarge Picture


	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!

	Crazy Tail V2 with Belt Drive Conversion all-in-one


	For LMH


	Crazy Tail V2 with elevated tail rotor kit. If you ever wanted the ultimate tail for your Corona, this is it! An enormouse amount of testing and development have gone into this very unique kit. The advantages of the elevated tail are numerous. First, the tail rotor is 3 to 4 inches off the ground. This gives the


	Enlarge Picture

	Enlarge Picture


	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. This kit is a must have for the serious performance Corona project.

	Corona X-Treme Rotor Head


	For LMH


	This rotor head has been specifically designed to eliminate the flex found in the stock head as well as increase the stability of the Corona. Made of 6061 T6 aircraft aluminum rotor hub for accuracy and strength. The follower arm is CNC machined out of Delrin. Delrin is a space-age plastic that has wonderful


	Enlarge Picture


	density and abrasion properties, making it perfect for the follower arm. This dampening is needed to retain stability when increasing rigidity of the head and main shaft. This rotor head was designed for the titanium main shaft upgrade only. It is bored to 5mm. It will not work with the stock 4mm main shaft.


	- The feather plate consists of a billet aluminum - ball bearing supported center hub and two carbon fiber plates - The carbon fiber plates are "Floating" type for better performance

	Carbon Reinforced Feather Plate ( V2 )


	For LMH


	The V2 Dampened Crazy Plate feathering plate for the corona replaces the stock head with this superior version. The dampening system is similar to an automobile suspension allowing for a smoother more controllable cyclic.


	Enlarge Picture


	The added dampening ( flex ) allows for a pre determined gain and gives an incredible smoother flight performance. This is increasingly important for fixed pitch Helis were the main rotor blades are fixed in position. Kit comes with instructions and all required hardware is included.

reason; The base of the shaft is 4mm to accept the stock main gear or "Hyper Drive". The main portion of the shaft that takes all of the bending load is 7mm. The upper tip of the shaft is 5mm for the rotor hub, and finally, the portion of the shaft, just below the rotor hub is 6MM to accept either the stock swash plate or the Eco-8 aluminum swash plate. This is a very versatile upgrade. Another noteworthy feature of this 7mm shaft kit is It's compatibility with the stock airframe as well as any after market airframe.

	Aluminum Corona Blade Grips w/ variable pitch


	For Corona


	The Corona is a fixed pitch machine thus controlling the angle of pitch degrease must be done mechanically. With these super tough and light blade grips you may choose to increase or


	Enlarge Picture


	decrease your pitch thus controlling your RPM. Use the lower pitch for higher RPM and more controllable flight while you may use the lower pitch for longer flight times and reduced damage due to a crash. Simply choose which one suits your needs and order the pitch angle which is available from 1.5 to 5 degrease of pitch. The kit comes complete with mounting hardware,


	- Available in 1.5 - 5 degrease of pitch - Machined out of solid aircraft aluminum for durability and lightness - Better performance and more controllable flight
