[edit] Change Frame Pipe of "China Frame"

For the original x-UFO there are many spare parts, but the framework unfortunately is not under it. If one of the carbon cross-beams breaks, can be repaired however easily and favorably even.

In most building markets there might be aluminum pipe with a diameter of 5.9 mm (or 6 mm). A meter of it lies concerning the price within the range of approximately two euro. Why aluminum and no carbon? Aluminum is easily available, favorable and can simply be processed. With a weight of approx.. 4 gram is a little heavier that 12.2 cm aluminum tubes than the original, but that is painful.

The tools needed for the repair are:

 * hack saw
 * 1 mm of drills
 * file
 * screwdrivers
 * soldering irons and something tin solder 

Besides still another metal thorn (lateral part with some taschenmessern), something adhesive tapes and cord valuable services can carry out flat-nose pliers, a thin fiber writer.

Loosen first all screws, which concern the defective carbon staff. At the best also the propeller of the arm concerned remove and the engine mounting plate completely open. Engine take out. The engine sits very firmly in the mounting plate. Well to remove it can be solved after the screws, as with the help of a flat article from above on the gear wheel pressure is exerted. Hold the remainder of the upper engine mounting plate.

Now and the cables, which lead to the engine concerned, unscrew the motherboard of the x-UFO, out-solder. The cable from the carbon tube raus pull. Now the carbon tube can be removed. If it sticks too firmly at the plastic parts, it can be crushed with the flat-nose pliers along the fibers. Now the Carbon"splitter should be able to be solved" easily from the plastic.

Now of the aluminum pipe 12.2 cm saw off, something with the file entgraden and times at the framework "try on". If it fits, one can mark the drilling points with the fine felt-tip pen. Put in addition the aluminum pipe into the plastic part and by the screw holes with the felt-tip pen one point on the aluminum pipe make. The point best directly with the metal thorn deepen, so that the drill does not slip later.

The two holes, at the UFO cross and engine owner, best successively make completely finished over to ensure that the propellers and/or engine axle are also also really perpendicular afterwards to the framework cross.

The first hole can be bored now. 1 mm is somewhat smaller thereby than necessarily for the screws. With the metal thorn the opening can be increased carefully to it fits.

If both holes are so far, the plastic cap can be put by the carbon tube on the aluminum tube. Now it goes contriving an's cables. With the tube folds still completely well, but it must also by the art off cross! Here the thread and the adhesive tape can be helpful. The cable ends with an end of the thread with adhesive tapes tape. The thread can be threaded better by the art off cross and then can the cable be pulled tight.

Now the cables again to the motherboard solder on and everything plug together and bolt. Now a first function test with Akku makes sense. If electronics functions duly, still times the screws can be loosened to the aluminum tube. Then vorichtig the tube somewhat pull out and to the appropriate points something adhesives on lay. Everything again plug together and bolt. Are stuck only the parts, which had stuck together with the carbon tube with the plastic!

The repair is finished. Completely ok flies. Loop problem-free possible.
