“The nicest sport aircraft you will ever have the pleasure of flying.”
TOPAZ DESCRIPTION
The Topaz is a full composite custom carbon fibre designed high wing monoplane with remarkable individual features and performance. The Topaz is fitted with a very efficient, full length, cantilever wing. The new 2018 Topaz XLS shares the same fuselage and identical wing profiles as earlier models, but differ in the following key aspects:
-
The NEW Topaz now has wing fuel tanks as standard with additional larger capacity reserve tanks located under the baggage compartment, it employs easy entry forward hinging doors with 2 huge baggage lockers (with external and internal access) on both sides of the fuselage. Fuel tank options of 86 lt or 105 lt.
-
The NEW Topaz is available with both the Rotax 912uls 100hp carburettor engine and the 912 fuel injected engine option. It's upgraded performance includes an increase in climb rate from 1200fpm to 1500fpm and an increase in cruise speed up to120kts with the100hp Rotax. The Topaz Vne is 136 kts.
-
A NEW constant speed propeller (CSU) option is also both available with the new TOPAZ.
-
The NEW Topaz has full-colour electronic flight instruments (EFIS) installed for no extra charge, optional equipment such as sun visors (like a motor vehicle), Beringer German lightweight brakes with tubeless aviation tyres, pilot and passenger adjustable leather seats, an optional rudder trim and now a brand new snappy paint scheme!
The electrically powered flaps and elevator trim are a dream to use, both push-button joy stick operated. This glider heritage mated to a full composite structure offers wonderful visibility, great range and superb comfort.
TOPAZ aircraft are manufactured from carbon fibre using vinyl-ester resins which have far better high-temperature thermal resistance qualities compared to the more conventionally used epoxy resins. The 120cm wide cockpit can also accommodate larger pilots comfortably - unusual in many light sport aircraft designs.
To reduce the chance of corrosion stainless steel components are used extensively, the flight control system is alloy and stainless - for improved safety only control rods are used, no pulleys, no wire cables and no Teleflex cables. The nose gear is stainless, even the engine mounts are stainless steel, so easy to keep clean with no rust and no corrosion.
An absolutely stunning full gloss paint finish (no gel coat), a smooth efficient exterior skin (no pop rivets), leather seats as standard, two large capacity cargo compartments behind each seat with lockable exterior access doors, heavy duty wheels and tyres, a ballistic parachute option, and much more.
Pilot and passenger comfort and protection are enhanced with a reinforced cockpit area, the high wing gives superior protection rollover compared to most low wing designs and the TOPAZ has an aircraft parachute option for additional safety enhancement.
The comprehensive instrument panel is equipped with far more than just basic instrumentation and can also be fully customized to individual specifications using any number of different panel layouts and avionics options. The TOPAZ features a very strong composite sprung landing gear with hydraulic disc brakes that are activated via the single brake lever with parking lock convenience all attached to a centre control stick.
The Topaz is not a copy of someone else's design, it is a unique and very special aircraft. No struts so less drag, no struts also ensure a better view and easier entry and exit, no aluminium wings so no 'oil canning' also no rivets so no corrosion, no carbon steel so no rust, you also won't find fabric covered surfaces used to offset weight limitations.
With a high wing there is no 'greenhouse effect' of cooking in the hotter months, if it rains you will not get wet on the ground or when getting in or out, preflight checks are so much easier (no crawling under wings), and service work is easier, no floors to pull up, the instrument panel comes off if needed with two bolts and two electrical plugs - brilliant!
The Topaz will reward the individual who appreciates fine handling and balanced controls. The wing design delivers spectacular climb rates and a phenomenal glide ratio, it achieves what few others can - at any altitude.
DESIGNED WITH ATTENTION TO EVERY DETAIL
The TOPAZ has a one-piece, tapered, strutless wing mounted on the fuselage. The airfoil section, NN1817 was used due to its very good aerodynamical characteristics and very high resistance to environmental performance loss.
The wing has a shell-like composite construction with an enclosed spar. Ailerons are made of carbon laminate designed with high stiffness and a relatively low mass for anti-flutter protection. Ailerons have integral mass balance elements at their ends. Electric controlled composite flaps are fitted to the wing.
The fuselage structure is made of two symmetrical pieces, dual-layered with a honeycomb core, which are joined together and additionally toughened. Pressure and temperature controlled mouldings are used, the process is unique and patented. The cockpit area is significantly strengthened for pilot protection creating a shell-like cockpit. The classic, tapered tailplane is a composite construction and an integral part of the fuselage.
Stainless steel push rod controls are used throughout for the flight controls with sealed bearing linkages - no pulleys, cables or Teleflex. Elevator trim is spring-actuated and powered with an electric motor controlled directly from the joystick. Multi-stage flaps are electric, also easily controlled directly from the joystick.
The windscreen is made of UV-resistance tinted Plexiglas, the doors are formed as carbon composite frames using 3mm Plexiglas. The main gear legs are made of glass composite. The main wheels have hydraulic brakes with parking brake function.
The plane is equipped with ROTAX 912 engine (80HP - 100HP) and a composite 3 blade ground adjustable propeller. The engine uses radiators and ducted air for cooling with no need for large, weather-exposed, opening in the front cowl. The engine mount is constructed of heavy-duty stainless steel for corrosion protection. An effective and efficient cabin heat system an integral part of the design.
