Hubsan X4 H502E GPS RTH Quadcopter

Looking for the perfect size quadcopter for this summer free youth RC training camp has narrowed down to this quiet 16.5 cm Hubsan X4 H502E GPS quadcopter. What caught our initial attention is the mini quadcopter with GPS, allowing the quadcopter to find it ways back. Other features of interest is it’s 720p camera and altitude hold.

The Hubsan H502e arrived in a small box with no instruction manual, but the usual short instructions on the packaging that reference a manual. The H502e is not even listed at Hubsan.com as such there is nothing to download.

Flight Characteristic
Slow and sticky to position hold even at expert mode on stock radio transmitter. However it binds with the X4 Pro FPV1 radio transmitter allowing you to fly in manual, gps and follow me mode.

What To Expect If This Your First

There is no user manual included.

You can easily spend 12 minutes on each flight, setting up and flying. The actual flight may last 8-12 minutes from our tests. On a Mode 2 radio transmitter, throttle stick is on the left.

Power on your quadcopter first, than the radio. Connect your battery to your copter, lay the copter flat on a hard surface immediately. This will allow the copter to self-level the gyroscope. Begin step 1 of calibration by rotating it horizonally a few round clockwise until the radio transmitter prompts you to complete step calibrate compass 2. Next, vertically rotate the quadcopter clockwise until the radio indicates complete.

When you are ready to fly, hold both sticks inward to arm the motors, the propellers will begin to rotate slowly. The quadcopter is now live and has entered into flight preparation mode. Motors does not auto shut off upon landing, disarm idling motors to avoid toppling over. To stop the motors, hold both sticks inward at the lowest point for 3 seconds.

There are dual rates by pushing the right stick in and hearing two beeps. It also shows Expert Mode on the LCD screen.  However it is still not a aggressive aircraft at all On the stock setting.

You can still maneuver the quadcopter during a GPS Return Home with the stock transmitter.

The copter LiPo battery may get a little warm after each flight. When the voltage is low (7.2 volts), it shows low battery on your radio (beeps on the FPV1), you should manually land within a minute to prevent the battery from over-discharging. Over-discharging a LiPo battery below 3 volts per cell, can permanently damage the battery. It is best to let the LiPo cool down before the next charge.

The odd size LiPo battery is not easily available.  Included is a USB charger for a 2S LiPo, slow but a useful charger to have around or travel with.

Undocumented Features
To bind with the X4 Pro FPV1 radio transmitter, you hold down the ENTER and power on the transmitter to initialize a bind.

With the FPV1 radio transmitter, you can now fly in Manual or GPS mode

Similar Model Aircrafts
Users have recommended these 2015-2016 alternatives: Walkera Runner 250 GPS, Hubsan H501s, JYU Hornet S, Walkera MR Drone. (Your contribution welcome).

What we love about it

  • Quick and effective GPS (12 satellites very quickly)
  • Hardy ABS structure
  • Telemetry on radio transmitter (gps, calibration etc)
  • Returns home when signal is lost or when battery is low.

What is essential we hope to see in the next version

  • User Manual and product information on Hubsan company website
  • Allow for full acro or high rates setup, as it seem to lack energy.

  1. Hi
    Very useful info. To confirm are you saying you can use the X4 Pro FPV1 transmitter with this drone ? If so can you see the flight view via the transmitter?

    Thanks
