I started years ago on the Syma S107 small indoor Infrared Coaxial Helo, the best at that time of small coax Helo and very stable, but tended to not hover in one place. Their new updated S107H-E here with height control just made the best small Coax helo even better. With the included now 2.4ghz controller, auto take off and auto land with height control, this is the easiest helo ever to begin and fly with. Now Being 2.4hgz you can fly outside on a calm day no problem with extended range. Inside this thing flys like a dream, extremely stable, smooth very little to no drift on hover. Outside the same as long you have NO breeze. This helo does NOT handle any breeze at all, outside or with any fans blowing inside. Mine had a very slight right drift on hover, I took the 2 screws out of the canopy and noticed the small weight was more on the right side, I attached the weight to the inside center of the nose, fed the light back in screwed on the canopy, no more drift. I fly mine all the time on the higher faster speed. The top right button is for fast or slow. The helo achieves the faster or slower speeds by raising the speed of the tail motor for more tilt for the faster speed. This is 3.5 channel helo, meaning left, right turn and forward and backward, there is no drifting side to side motion, that's only on 4 channel helos. Battery gives you right at 6min. flight times and a 15-20min. charge time, so plan your flights out. Don't loose the USB charger, cause it requires that exact charger to charge the permanently attached battery under the canopy. You can snip the wires and replace the 150mah 3.7v battery if that one ever goes bad, I would recommend a 220mah 3.7v battery and leave out the nose weight for another 25% flight time, only if you feel you can rewire in another battery, the stock battery charger will work with a 220mah battery as long it made for syma helos. The auto take off and auto land is a nice feature and that's the upper left hand button. The 2 smaller(left and right) side buttons on the controller are made to adjust if the tail boom does not stay steady and you can adjust it for which ever way the helo is spinning, to counter react and to stop that movement. Being Stuck inside this is a little nice relaxing helo to fly around in those closed in days, or no breeze outside mornings. Here is a list of improvements.
1. 2.4ghz receiver/transmitter
2. One Button auto take off and hover
3. One button auto land and motors shut down
4. Height/altitude hold
4. Fast charge of 15-20min.
5. Up to 7min. flight times
6. New Multi color LED's
7. New Modern Controller
8. Nose weight now inside canopy
9. New Flybar Design and location

Wish this product had a longer battery operating time.

Once I learned the proper set up sequence (which took a couple days) this little heli is my favorite!

In cold Chicago weather, my 12 year old grandson uses this drone in the basement and alternates with his outdoor drone (when weather permits), using his iPad and doing other inside activities.
We followed the advice of other reviewers and charged the drone for a couple or hours for first use.
Each charge lasted about 7 1/2 minutes.

Arrival fast. In time for Christmas!
