How to fix Hubsan X4 transmiter

My Hubsan X4 (H107) had developed a problem synchronizing with transmitter (tx to rx). Since I had to disassemble it completely and solder broken battery cable I wasn’t optimistic that I could fix it. But I knew the quadcopter was flying after my repairs, so I kept thinking that the problem may lay somewhere else.

I suspected the transmitter. Symptoms below were appearing in random order:
* Hubsan X4 established link to transmitter (LEDs on), but does not react to throttle
* Link is established, but drops immediately – LEDs flashing on quad-copter or LED flashing on transmitter
* Red LED flashing quickly on the transmitter

I tried all the usual IT magic: turn it off and on again, shake, press all buttons in random order and combinations etc. with no result. I tried to do the factory reset and recalibration – the transmitter did not respond to that. I needed to think outside of the box. And then it hit me!

The solution was (drumroll…) to change the batteries in transmitter.

The Hubsan X4 transmitter has a battery status build in, but it seems to be broken – it was showing more the batteries still have 3/5 of the juice while the batteries were clearly dead.

Probably the best sandwich in the world!

Yesterday I have invented the best sandwich in the world! Some will call it gourmet!

Here is the recipe:

  1. Toast two pieces of Warburtons medium white bread (or similar – any good white toast should be ok).
  2. Spread a medium layer of Red Onion Chutney (I recommend English Provender Co.) on one piece of toast. Let it sink in a bit.
  3. Pour some Red Hot Buffalo Chicken Wings Sauce (I recommend Frank’s) on the other piece of bread.
  4. Cover the onion chutney with a medium slice of fresh, mild gouda cheese.
  5. Put a think slice of a thick Chorizo sausage in the middle.
  6. Put generous slices of sweet tomato.
  7. Add two slices of strong, white onion.
  8. Put few cucumber slices on top of the onion. Add salt.
  9. Close the sandwich. Cut and consume immediately!

I have no photo of this exquisite dish, because the sandwich disappears before I manage to find a camera. Try it!
