	Item	Price

	Shock Absorbing Nose Gear: This great option is a direct retrofit replacement for the existing nose gear. Unlike some of the expensive gas shock designs and other spring shock styles that require welding, this upgrade installs in about 30 minutes and requires no welding. Includes new nose fork.	$115
	Light Sport Special Shock Absorbing Nose Gear. The LSS Shock Nose gear is designed for the 6" LSS nose wheel, and can also be used on other Challenger models that have been converted to 6" nose wheels.	150
	Hinged Front Windscreen: If you have grown tired of sliding in the front seat of your Challenger by working your way around the windscreen, this is exactly what you need. Retrofit modification installs easily to your existing windscreen in about an hour and allows direct access to the front seat. Includes everything you need to install. Pre-formed tubes, complete instructions and detailed photos. You will wish that you had installed this option a long time ago! Picture	85
	Heater. We make them here, for installation on the 503 (and 447 with slight modification) motors. Includes the heat collector, butterfly apparatus, single cockpit control, flange and ducting for the cockpit. These heaters are complete kits, and ready to install on your aircraft. Picture	155
	Nose Gear Support Plate. Fabricated out of aluminum plate, and provides additional lateral support for the nose gear. Helpful in side load landings (not that you would ever do that). Picture	45
	Swivel Tail Wheel. Standard tail wheel is fixed, so when the plane is on the ground you must pick up the tail to move it around. It moves straight forward and straight back without any problem, but is a little awkward to turn. Recommended for pavement or other hard surface operation. Requires use of your existing bent aluminum tail wheel brackets. Picture	20
	Aluminum Front Seat Back Support. Standard design has a small piece at the top area of the seat, and another small piece near the bottom. We suggest adding this update to provide solid support for the entire seat back area.	35
	Aluminum Rear Seat Back Cargo Pocket. The standard configuration for the rear seat is a small piece of thin wood, hinged at the bottom, which serves as a support for the rear seat back, and allows access to the fuel tank. We suggest replacing the wood with an aluminum door, which we fabricate to include a pocket on the rear that will hold 3 quarts of engine oil (or other small items). Will work with 5 or 10 gallon tank, will not work with Canadian 15 gallon tank. Picture Picture 2	110
	Front Sling Seat Conversion Package. Complete retrofit kit to convert your old sling style seat to the new aluminum version. (This item converts the seat bottom only. You can use the existing canvass seat back with this seat bottom conversion, or purchase the Front Seat Back Support sold above).	79
	Rear Sling Seat Conversion Package. Complete retrofit kit to convert your old sling style seat to the new aluminum version. (This item converts the seat bottom only. You can use the existing canvass seat back with this seat bottom conversion, or purchase one of the following items: Rear Seat Back Support sold below, or Rear Seat Cargo Pocket sold above).	98
	Aluminum Rear Seat Back Support. Replaces the small piece of wood that makes up the rear seat back with 6061-T6 aluminum	39
	Horizontal Stabilizer Fins. Made of aircraft grade plywood, and includes all mounting hardware. These fins are attached to the ends of the horizontal stabilizer, and assist with additional yaw stability, most noticeably when the doors are installed on your plane. Supplied epoxy primed and ready to paint.	75
	Front Floor Board (Challenger II Only). We construct these out of aluminum, with extrusion stiffeners on the underneath side. They are strong enough to rest your feet on in flight. Picture	95
	Aluminum Engine Area Bulkheads. The area in front of and below the motor of the Challenger is normally covered with fabric on the standard planes. We suggest installing aluminum in place of the fabric on both surfaces. It ads very little weight, but is much easier to wipe down (there will be oil on these areas frequently) and it looks much looks better (in our humble opinion). It also helps if you ever drop a spark plug while changing them (no fabric to puncture), and makes it much easier and cleaner looking to run your wiring harnesses through. Includes all necessary nylon snap grommets. Picture	95
	Aluminum Instrument Panel. .050 aluminum, and made to the same size and shape as the standard wood panel template supplied by Challenger. Can be supplied with a bend to vertical towards the top or bottom (no extra charge) to allow additional leg/knee room for the front seat occupant. (on the standard panels). Larger sizes and shapes are available, based on your instrumentation. Also available cut to fit your instruments, switches, etc. Email us for a very reasonable quote. Picture	65
	Added Aluminum Attachment Points for Lower Wing Skin. This is a modification that we do on almost every Challenger with Stits wings (it is not necessary on Sailcloth or Mylar wings). The normal covering method has no attach points for the fabric between the inboard and outboard ends or between the front and rear spars. In essence we attach a small "L" angle piece of aluminum onto each compression strut in the wing, and then attaching the fabric on the lower surface of the wing to the "L". It allows for more uniform shrinkage when the fabric is tightened, and will help keep the fabric from rising up (approximately 3/4" to 1") in flight . The fabric gets riveted to the "L" just as it does to the ribs on the top surface of the wings.	125
	Stainless Exhaust Clamps. The standard clamping devices for the Rotax muffler are a series of springs that are often problematic. They often break, and can damage your prop if they fall off in flight. The exhaust brackets in this modification are made of stainless steel, use all AN hardware, increase safety and reduce the possibility of expensive prop damage by a broken spring. Price is per clamp, and 2 are required. Trust us, you want this option. Picture	38
	High Density Seat Bottom Cushion. Suggested for the bottom cushion of the pilots seat (or both, if you like your passengers that well). Good for increasing the comfort level on longer flights (1.5-2 hours or more).	19
	High Density Seat Back Cushion. Same high density foam as listed above, but cut to replace the factory foam in the back part of the seat.	23
	Aileron Gap Seals. We use a 3M material, which does not crack or dry out. Consists of enough material for both wings. This is not required on Sailcloth or Mylar wings.	11
	Removable Nose Cone Panel. The standard installation for the fiberglass nose cone is to permanently attach it to the airframe. The problem with this is the fact that the battery and Hotbox usually need to go in the front of the nose, making it difficult to service them if necessary. It is also difficult to get to the rear of the instrument panel with a permanently attached nose cone. We cut a panel in the top front of the nose cone, allowing access to the battery, panel and Hotbox, as well as nose gear assembly. The access panel is approximately 12’ wide and 18" long (front to rear of aircraft), and held in place with stainless machine screws (which can be painted to match your aircraft) and plate nuts. The panel is cut out using a jig, then a lip is glassed on the inside to install the plate nuts to, and support the panel. The cut out panel is reused as the access door. (Done by our friend and co-worker John, whose wife Patti cracks the whip and makes him do them to her exacting specifications ;-)). Cost is installed on YOUR nose cone. If your nose cone has not yet been shipped to you by the factory, you can have the factory ship it directly to us to make this modification. Finished cone is shipped to you freight collect.

	Battery. Sealed, no maintenance, 12 volt, 18-20 amp.	105
	Battery and Hotbox Mount Structures. We use this option on every aircraft we assemble. We extend the front of the longerons about 10" and make a platform out of extruded "L" angle to support the battery and Hotbox. The battery then sits in front of the rudder pedal stop bar. The Hotbox is mounted above and aft of the rudder pedals, in front of the instrument panel. Mounted here, both are out of the way, and do not get kicked or bumped when entering or exiting the aircraft. If you choose to have the access panel cut into the nose cone, the battery and Hotbox are directly below the panel opening, allowing easy access to the connections on both. Picture	90
