Make a Hubsan X4 fly like an Iris

Posted by JB3 on March 21, 2014 at 2:05pm

I bought a Hubsan X4 to practice with while waiting for my Iris to arrive.  I highly recommend using something like the X4 to practice before flying the Iris (and I see many others here recommend it too).

Some X4 models may not have the throttle on the left like the Iris.  You can correct this with some cheat codes to change the mode (no need to open the case and swap wires). 

I apologize for not having better notes.

It's either:

Hold both sticks up+left, turn on the transmitter, hold hor trim button.

or

Hold left stick up+left while holding right stick down+right

Again, apologize for the bad notes.  I'd be happy to Google with you and experiment if someone is really struggling trying to get this to work.

    Hey Joe,

    You are describing what RC folks call control Mode 1 and control Mode 2. Mode 1 (throttle on right) is common in Europe, while Mode 2 (throttle on left) is common in the USA. The Hubsan X4 can be ordered with the desired mode.

    The Hubsan X4 manual describes the operation you describe on page 23 of the manual as "18. How to Recover the Factory Set". I do not own this model as I am a Horizon Hobby Blade fanboy, but the Hubsan looks to be a nice practice airframe. I am considering purchase of this model as a gift, so I am curious as to the ability to switch the Hubsan transmitter modes using the sticks and the "Recovery" procedure on startup. Would you confirm that the mode from the factory can be switched using the "Recover the Factory Set" procedure? Can you switch the modes from one to the other and back easily?

    Thanks in advance.

      I tested it over the weekend.  To start the transmitter for my X4 was set to M2, then I did the recovery procedure to change to M1.

      Then I held both sticks up+left, turned it on, and while still holding the sticks to the upper left I pressed the aileron trim button to the right.  Now it's back to M2.

      M2 means throttle on the left for the X4. (I tested taking off to verify which stick was active after each change)

      Kool! Thanks Joe for taking the trouble to verify the software mode switch. That is a neat little feature that is not so easy on my 'big name' transmitters.
