I seem to have difficulties posting just after 09:00 EST for the last few days.
Deleted my posting that I could not edit to correct spelling.
does the transmitter let you know how much flying time is left, so you can land plane safely? what type of flying range is there with transmitters?
Here is a BMW R69S rider.
You got good info from BuaschBarber on the timers.
Concerning range, the basic necessityto fly is to be able to see the attitude of the model in pitch, yaw and roll. Quite obviously the size of the model allows longer distances (range needed).
Full range transmitter /receivers allows us to control the larger models as far as we can see their attitude. The ability to see their attitude varies due to many factors ____
Shape of the model,
The color scheme,
The direction the model is flying,
The background sky conditon,
The antennas orientation relative to each other,
The healthy conditon of our batteries
and so on . . . .
Electronically speaking the maximum range is limited by the signal to noise ratio at the receiver.
Conclusion is that we do not have to worry about range if we keep our batteries in good maintenance and charge level good enough for our flying time.
So called "park fliers models" rigs (equipent) have shorter range and should not be used in larger models.
I have never tried to fly a model while holding or relying on binoculars
