Syma Forum

VMSDA, They are very brand-specific. Syma Tx will not work with WLToys, for example.

Other bad news is there really is no way to increase the signal strength of the remote

or to increase the reception area of the S107 itself. Keeping out of direct sunlight, not

flying near mirrors and flat-screen TVs helps, though. (Plus keeps your household

goods out of danger!)

  There is a bright side here. Syma, as a company, is huge! They make their own products as

well as models for other brands. Toys-R-Us and Radio Shack and a few for Wal-Mart. That said,

if it looks like a Syma, disregard the first sentence! The dead-givaway is the shape of the

remote itself. I bought a Helizone Firebird 3 years ago because of the cool graphics and

I prefer to use my S107 remote to fly it. My Syma remote still has a left-stick spring.

Yes, you can use the same remote to fly different IR Symas as well. The 107 Tx will

also fly the S109 Apache and S111 Coast Guard to name a few.

  Once you get outdoors, you'll find the same true with the Rx. It will fly most outdoor Syma

(S31,S32,S33, etc) as well as Double-Horse branded products.

   Hope this helps! 

Vmsda,

   Thanks for your inquiry, and a big welcome to the forum. I'm not sure if

we have anyone for Portugal on here so another great big welcome and thank

you for your interest.

   To answer your question, there is no real way to tell if the batteries in the 

transmitter are going bad except if the LED light does not come on when you 

turn on the power to the remote via the switch. If this happens, you have gone

well beyond what 6 AAs can do!   However.......

   One thing I have noticed with mine is that the copter will fly irradically and

not respond to my movements on the control sticks. Also the heli gets

"bogged down" on a seemingly normal flight and will drop out of the air for no apparent reason.

Luckily these little guys are tough and can survive hard crashes. Mine quits when I fly it

into a certain corner of a room with no obstacles, TV, lights, etc, and just falls down.

Time to change the controller batteries!

   Good news is if you use a good quality battery such as Eveready or Energizer which

we have here in the USA, you should get tons of hours on one set of batteries.

   Good luck and safe flying, and please report back often.

                                                                        Welcome once again!
