National Ultralight Challenger 582 Power Pack

The National Ultralight Challenger 582 Power Pack incorporates the Rotax 582 UL DCDI Mod 99 engine and includes everything you need to produce thrust.

This engine, the well-proven second generation "Blue Head" version, has numerous internal improvements to enhance reliability, the benefit of Rotax's substantial real world service experience with the initial generation. The engine comes complete with dual electronic ignition, two spark plugs per cylinder, dual carbs, impulse fuel pump, air filter and a quite effective muffler. Custom exhaust mounts are used. We developed a new motor mount with eight Lord mounts to isolate the airframe from vibration.

The standard 582 Oil Injection system includes the oil injection pump and control as well as two oil tanks which mount on either side of the rad. In this setup the owner puts pure gas in the fuel tank instead of pre-mixing with oil. The metering system, based upon engine rpm and throttle position, delivers exactly the right amount of oil to each cylinder via diffuser jets in the intake manifold sockets. The tanks are quite large and contain oil for 10-12 hours of flight! The oil tanks have individual sight gauges and both gauges are visible from either side of the airplane. The oil tanks are designed with outlets front and rear and they are cross-linked so that oil is available in all flight attitudes.

The 582 is liquid-cooled via an engine-driven water pump and thermostat so we include a complete radiator setup with everything you need to go flying. There are no trips to the hardware store, or the engineering department! This updraft rad mounts in front of the engine on top of the wing parallel to the airflow rather than perpendicular so it creates the least possible drag. It is quite large to avoid overheating on even the most trying days in the most trying circumstances.

An integrated generator produces AC current (12V 170W) which is converted by the supplied regulator/rectifier to 12V DC (nominal). Electric start is standard with our package. Also included is a backup manual recoil starter.

The reduction drive is the preferred "tall" 2.6-to-1 unit which turns a 60" prop.

The Canadian Challenger 582 Power Pack comes with the top-of-the-line Warp Drive 3-blade ground adjustable prop with carbon fibre blades with wide tips.

A wonderful aspect of the 582 is that the peaks of the horsepower and torque curves overlap and are quite flat plus start at a relatively low rpm. This allows the prop pitch to be set into the peak power range without giving up on cruise! The 3-blade configuration is required to get all the 582's horsepower out into the air as thrust - a 2-blade prop wouldn't have enough disc area to do this.

Chargeable Options for the Challenger 582 Power Pack

OPTIONAL Warp Drive Upgrade

This option upgrades the Warp Drive to the HP-L hub and adds Leading Edge Protection. The machined aluminum HP-L hub makes tracking easier and it's lighter and prettier than the STD hub. The solid nickel leading edges protect the blades from spray, slush and rain. Leading edge protection is strongly recommended for operations on floats.

OPTIONAL All Season Kit

The optional 582 All Season Kit provides cabin heat via a remote heater core with 3-speed electric blower and ducting plus cockpit-controllable louvres for modulating the airflow through the rad. The top and bottom louvres function like cowl flaps on high performance airplanes or shutters on motor vehicles.

When the louvres are open they allow maximum airflow to avoid overheating during taxiing or prolonged climbs on hot days. When closed they prevent overcooling during extended descents at low power settings. The louvres can be set to any interim position to keep the coolant temperature in the green - right in the middle of the operating range - for maximum reliability.

This All Season Kit is strongly recommended if you are going to be flying in cooler or cold seasons, or chilly climates, or at high altitudes.
