How to change an electric aircraft so that better withstand shock

How to change an electric aircraft so that better withstand shock
As you can see in the photos of 3 years ago (before and after the bump in Auger) electric RC airplanes are very good to start in this world of radio-controlled flight, but we need to make sure that our model is going to take quite a few hits if we don't want to ruin us;-).



The plane for initiated
OS I recommend for those who go to buy his first aircraft, first practice in PC flight simulators with connection to real control either that a person with practice to teach you, letting you control when there is no danger; It would not be the first time that a happy life bought a plane of gasoline of 600 euros and destroys it the first flight.
One of these gliders featured (3 channel throttle, rudder depth and direction) is ideal for starters, but even better is a pure large-winged glider and all functions; There are very cheap and easy to use that even make stunts.




After giving me several times of snouts and fix it over and over again using Epoxy glue (rapid adhesives is the only one that goes well; as the imedio eat the porexpan) it occurred to me to put something allowing the nose to cushion the blow, receding, and I turned to create a nose of rubber with a stand of plastic and light coverage engine to improve the nose aerodynamically.

Material needed:

  • Piece of rubber of Chamber of the tire of a bike for example.
  • Adhesive epoxy two-component fast drying (5-10 minutes).
  • Scissors
  • Blade (cutter).
  • Piece of thick and slightly flexible plastic for the motor bracket (a bottle of chocolate milk CAP could be worth if two pieces are joined together using glue to give hardness).
  • Rubber bands to attach motor to the bracket.
  • Soda pot to cover the nose and give better drag coefficient.
  • Propellers, retractable is not break to sink into the Earth, on sale in shops of model airplanes and radio control.
  • 40W soldering iron desoldering and soldering new engine (the polarity is important).
  • Piece of black rubber to prevent the motor shaft back (recommended).
  • A dremel or similar would be very suitable for cutting plastic and make holes (optional).
  • And the plane, obviously, for about 120 euros at import stores.

Steps to follow

  1. The first thing is to give shape to the rubber cone shaped, overlapping and pasting a part with the same epoxy. Then we can trim the morro to position and glue the cone, which we just did; It is important to leave the plane with approx. the same measures that had the nose before (the position of the engine is crucial). Then cone sticking carefully to the chassis of the aircraft and cut the excess rubber so that it is straight.
  2. We make a stand for the motor with plastic and epoxy. If you doblas and ties the piece of plastic that will hold the plane with a rubber motor and give some heat, it will tend to take the form. You can then paste it to the base of the motor bracket.
  3. Then (already there is less) cables are passed through a hole in the base (it is convenient to pass them before attaching the base rubber), solder them to the motor and place it on your website.
  4. Finally placed the mouth of a 2 liter soda bottle (some orange Kas are more appropriate for its lightness and shape), holding it only with a little tape transparent packing; It should take into account that when the plane touches ground with the nose after one of our forced landings (one other always plays) this part will go slightly backwards.
  5. Details, and only remain as cut mouth to let pass the air to the engine, place a small rubber just behind the motor shaft so that it desgaƱite to hit against the ground and place the retractable propeller.


In this image looks with a transparent plastic that I changed for their fragility.


Finally I was so (image above), with a hard plastic 1.5 mm flexible trimming cutting the base of any boat that we have at home. Notice that looks the part of black rubber that will overlay on top of the other.


And this is the final appearance of our new racing car. Here is not, but later placed him a small sink of very light aluminum on the engine seized with the gums to be fresher. If you look the front of engine must be ventilated.

Behavior differences in flight
With these changes the plane won around 50 Gr. lightly catching the trend to lower the nose that was easily corrected with the remote control. On the other hand to improve the size of the blades and the drag coefficient, we get more autonomy and speed.

Final conclusionsWe have modified our airplane and we've had us well in the process, which F1 engineers, looking for lightening or keep the weight of the nose giving strength at the same time, and over us has been good, how boot the airplane to kiss the ground, just remove the land of the propeller to be able to continue to enjoy!
