I am looking at 2.4 ghz radios and I have gliders and am making a boat.
Can I use the same 2.4 ghz TX for a boat as I would for a glider?
I have a high chance of getting a 2.4 ghz TX that was used with a Heli and just want to know if it would be legal to use with a boat as well.
any info would be great.

Yes

There are two frequency bands in the US that can be used for basically any R/C vehicle, 27MHz and 2.4GHz. This also applies to the 50MHz band, HOWEVER an FCC license is required for a modeller to use that frequency band due to the fine tuning that can be required by the R/C equipment

It seems that I read somewhere that the surface radios and air radios aren't meant to be used for the same application.  Don't remember if that's true or not.  I always used two different radios for my heli and boat.  Hopefully someone with more insight will chip in...

Only applies to non-2.4GHz radios.
This is to prevent someone using a surface model controlling a flying model by segregating the bands that they work on.
Any crystal fitted TX will control any RX in the same band with the matching crystal. 2.4GHz equipment works in a very different way - once a receiver is bound to a transmitter, only that transmitter will control that receiver. The difference is in the labels on the controls - few boats need a collective, few have ailerons or elevators, while few planes need a reverse, many boats do, similarly, wheeled models need brakes, boats don't.
