Joystick getting too warm???

[vj]

Hi all:

Complete newby, recently purchased LamaV3 4Ch heli, learning to fly on FMS before destroying the real thing. After a lot of help from reading the Forum, got the set-up to work. However the [b]transmitter (0404) gets very warm [/b]in the bottom left hand corner above the 35MHz Xtal, and the battery indicator keeps going down. In the simulator, the trim settings keep drifting, making it v difficult to learn to control the flight.

Should the Tx get so warm as to be felt outside on the plastic case after only about 10 mins? This represents a substantial drain on the AA batteries. How long should a set of 8 alkaline batteries last? - mine gave up after only about six 15 min practice sessions.

None of the controls remain steady for more than a minute!! The sim heli goes into see-saw motion forward and back (nick), continuous circling, yawing, etc., v frustrating to make it do anything you actually want to.

I have not even bothered to try the real machine, and am not a happy bunny. Has anyone had similar experience or can shed light on this?

Feedback/advice highly appreciated as always.
Thanks

I usually get a few hours out of a set of AA's in my Hitec 3 channel controller.

Try running your radio the normal way: no buddy connector, antenna extended.

I've seen this effect on ham radios when the antenna was loose: you might be overloading the transmitter by running with the antenna collapsed.

If it still runs down fast, then you probably have a bad transmitter.
