Power system

A single 64mm fan unit with a brushless inrunner motor mounted at the factory powers the Eurofighter on the kit 3s 1600mah lipo. According to factory specs, the thrust output of the fan unit is in the 16oz range, which on paper should give the Eurofighter plenty of power. Bench testing showed my setup making just under 250W @ 20A on the stock freshly charged battery, and about 275W @ 24A on a 2200mah 20C pack that I also had in the workshop. Either way the stock 30A ESC is more then enough to cover the demands of the fan/motor combo.

Assembly

Simply glue the wings and canards in place, install your landing gear, plug in your servo wires, charge up your battery, and head out for your maiden. If you've got some build/assembly experience, I'd bet you could complete the assembly in the amount of time it takes to charge the battery with the supplied wall charger (about 30 minutes for initial charge).

Wing

Main Wing

Attaching the wings has you push the tabbed wing into a pre-cut slot on the fuselage for both the left and right side. Ensuring the wings are aligned properly is done by simply keeping the top / bottom of the wing flush with a ridge that runs the length of the fuselage. The servos and control linkages are already done at the factory, so once the wing is in place all that is left to-do is to plug them in.

Canards

The Art-Tech Eurofighter comes with fixed canards, and installing them requires you slip the tabbed end of the canard into a pre-cut slot on the fuselage, and glue them into place (just like the wing). Aligning the canards is done for you once the canard is fully inserted into the tab, but you'll want to ensure everything looks symetrical before you glue in place.

Completed assembly

The only remaining step that is required to complete the fuselage is attaching the nose cone. Simply glue into place after it's aligned appropriately.

Tail

Being a delta wing, there is no horizontal stab, and as the vertical stab is molded into the fuselage there is no assembly required. As with the rest of the kit, the rudder servo and linkages are pre-installed at the factory.

Landing gear

The steerable nose gear is installed out of the box, so all that's left is to install the pre-bent mains which plug into a plastic base plate that is pre-mounted into the wing, and are held in place by 4 screws. For this step, I found it neccasary to clean out some of the flash left over from the molding process which prevented me from getting the gear to mount flush inside its housing with my exacto blade.

Radio Installation

All that remains for the builder to-do is to plug your servos into the RX. To gain access to the RX, start by removing the bottom 'cover' which retains and masks the electronic components installed underneath of it from the bottom side of the aircraft. Then plug your servo leads into the RX. I recommend you verify everything works as expected and then once you're satisfied everything is operational, pop the 'cover' back into place and secure with the provided screws.

Completion

Completion of the model consists of balancing the model, charging the battery, checking your throws , and gluing the wing tips on. The battery took about 30 minutes to charge on the provided wall charger, and then I was off to fly! As there is no mention of throws in the manual, I feel it's worth noting that I did not use the stock settings for the control horns on the ailerons. I ended up adjusting them so that they are placed in the hole closest to the aileron itself (ie maximum throws).
