Default How many flights before changing batteries?

If I use non-rechargeable batteries in my tx, how many flights (or how long) before I should change my batteries?

Which TX to you have? All the TX that I've seen have a light system or some type of indicator telling you when the volts are getting low.

I've got the one that came with the Edge, it only has an on/off indicator light. My Futaba has a meter.

I use energizer batterys in one of my transmitters and they last a long time, havn't counted the number of flights though. Use a volt meter once a week to tell when getting low. The crystal in your parkflyer transmitter should work in your futaba xmtr. Why not use the futaba transmitter? I do on my parkflyer.

If this is the Art-Tech Edge 540, the radio will either have an audible warning (loud continuous tone) or the on light will turn from green to red when the battery becomes depleted. It seems the earlier Art-tech radios had the audible warnings and the later the changing colour of the light. I much prefer the audible warning as I don't watch the transmitter when I'm flying!

No. You should not just swap the crystal from one transmitter to another. First of all, it's illegal! If you change the crystal in a transmitter to a different frequency, the transmitter must be professionally re-tuned to the new frequency.

Secondly, without re-tuning, the transmitter may produce less power and/or produce interference that can affect your airplane and those of others flying around you.

Its not illegal to change freq on your transmitter. If the xtal is compatable with the xmtr. I don't think changing channels on a 72 mhz xmtr would require tuning. I know all xtals are not compatable with different transmitters but I think most Parkzone and Futaba units are interchangable...at least mine was.

The TX will go from green to red when turning on and may give audible.

To be safe, would do range check at 100 feet with antenna down each time you fly.

I would estimate you get around 6 hours use before the batteries go dead.

Why not just get rechargable? They cost a little more, but last A LOT longer than regular batteries. And by purchasing eight, you can use them for a variety of things around the house. I used to hate spending that much on rechargable batteries, but now, I don't even blink an eye, since I end up saving so much in the longrun. Trust me, its worth it.
