CARF Ultra Lightning

Ultra Lightning (Silver/Orange/Black Scheme)

CALL TO ORDER

Description:

The Silver/Orange/Black Scheme on our Ultra Lightning was debuted at Florida Jets 2008. It is a very impressive and highly visible color combination. Still it looks classy on the ground. There is enough room to customize and individualize the plane with stickers, logos or pin striping.
General Information

The CARF Models Ultra Lightning is a brand new cutting edge Sport Jet. It’s based on our classic Lighting. A tremendous amount of feedback from our valued classic Lightning customers has enabled us to move an already state-of-the-art design to a never before achieved, ultimate level. Still affordable, the CARF Ultra Lightning combines brilliant design and engineering with modeller’s experience. The Ultra Lightning is the result, the climax of years of Sport Jet Development. We at CARF Models are absolutely convinced that our Ultra Lighting can very well be compared with the best designs out there and we don’t even feel challenged. With one undisputable advantage. It’s affordable. Not “cheap”, though. Besides that it’s fast. It’s big. It’s beautiful. It stands for ultra performance.

So, besides the performance, what else do you get for your money? A highly pre-built, brilliantly painted Sport Jet of very impressive size. All control surfaces pre-hinged, control horns installed, servo mounts built in. Double walled thrust tube, carbon turbine bypass, readily installed and blended intake duct. Twin kevlar fuel cells with 5.8 l capacity. Removable nose cone, preinstalled large bottom hatch and canopy frame. Slide-on wing panels with gear frames made from solid carbon fibre. Detachable stab and fin. Even more complete than you’d ever wish for.
Fuselage

The Ultra Lightning’s fuselage is a very strong hand laid up structure, air intakes glued and blended in. 20% more air intake surface area than in the Classic Lightning let even the strongest engines breath freely. Two formers are readily installed to hold the engine and to align the intakes properly. The removable nose cone and the removable fin makes transport and storage easy. However, the Ultra Lightning, due to its swept back wings, thus uncritical CG position, does not necessarily hold any batteries in the nose cone, so the nose cone removal is really optional, but quick and easy. A giant hatch on the bottom with a safe 6-point fixture allows easy access to engine, ducting, thrust tube and fuel tanks. Therefore no further hatch is on the top side of the fuselage to prevail the clean, slick and tidy looks. The large canopy acts as the RC access from the top. A horizontal RC board keeps all components in place, both electronics for the engine and radio equipment. There is plenty of room for your installation, which also allows all kinds of varations, whatever you prefer. The canopy is held in place with one single bolt.

 
Flying Surface:

The biggest difference compared to the classic Lightning are the swept back wing and stab. Besides a better CG situation they make the plane look faster and meaner, on the ground and in the air. Nice free shape wing tips do not only increase the wing area, they reduce the induced drag of the wing at both high and slow speeds. A large access hatch is combined with the gear door. The 40 mm aluminium wing tube from anodized highest grade 6061 aluminium is supported by 6 wing ribs, which will take all the G-loads possibly generated by hard flying and is designed to even give the gear mount additional rigidity.

As usual, all control surfaces like aileron, elevators, rudder and flaps, are skin hinged. This is a very rugged and reliable hinging method and it is aerodynamically the cleanest possible. Dual control horns hold heavy duty ball links, everything readily installed for you. The control surfaces are carefully sized so that at highest speeds a very smooth flying is possible, but still, in the slow flight mode, they have sufficient authority to throw the plane around the corners almost in 3D style. Snaps are as well possible as walls and flat spins, always keeping the speed induced flying loads in mind.

 
Fuel System and Turbine Mounting:

With the CARF Models Ultra Lightning you get a complete package, which includes well proven fuel cells, plumbing materials, a hopper tank and a monocoque type carbon turbine bypass. All this is installed for you and you only have to mount the engine of your choice into the bypass, plump the tanks with clunk and fuel lines and connect them to the fuel pump. For this “no fuss” installation we gurantee trouble free operation from the first minute. Even though there is almost 6 litres (1.5 gallon) capacity with the saddle type fuel cells included in the kit, we offer an optional 3rd fuel tank to extend flying time even further or add a smoke system – if you wish even add two and take care of both.

The dual walled thrust tube is designed for engines up to 20 kg (44 lb) thrust and is working only in a fully enclosed installation. This is very safe, as it guarantees very cool running of the engine, thus keeping the inside of the fuselage cool, too. We have been asked about the possibility of using aftermarket thrust tubes, which basically is no problem as long as it is a design of a well experienced manufacturer such as TamJets, who understands the design of the full flow bypass. You might gain a weight advantage with an aftermarket thrust tube, but we state clearly that the included thrust tube is working safely and at maximum efficiency.

Conclusion:

The Ultra Lightning is Ultra in any aspect. We have successfully refused any possible compromise and have created a mile stone in jet modeling. You can’t overlook the Ultra Lightning if you are looking for an ultimate Sport Jet. On the work bench and in the air there’s nothing out there coming close.
