This is related to the batteries in the Transmitter.
The X5C really likes fresh batteries in the transmitter.
Using my Voltmeter, I've found that range starts to decrease rapidly once the batteries drop below 1.54 volts.
Brand new fresh AA batteries can read about ~ 1.59 - 1.61volts give or take a few tenths.
My range (I did the 5dbi antenna upgrade) is about 300 ft with fresh batteries. A little more vertically.
By the time the batteries are at 1.52v, range has dropped to about 80 ft. Huge difference.
By the time the batteries are at 1.50volts range is down to around 50 - 60ft.
Since the TX uses four batteries, that translates to a significant drop in range at 6.0 volts total.
Range is best at 6.4 volts. Seems like a small difference but in the TX it makes quite a bit apparently.
But don't throw them out! 1.5AA batteries are good in almost everything else until about 1.35 volts so there's a LOT of life left in them after they come out of the Syma TX.
You might want to keep an inexpensive Voltmeter and a pack of fresh batteries with you when you go out to fly.
Hope this helps someone.
