With the CARF UltraLightning 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.
