Quads will crash and break - but your TX will stay with you.
While there are undoubtedly many great transmitters availble, it is worth noting that since this is hopefully a one off purchase you may as well spend wisely and get something with enough features to ensure you get value and good use out of the device. We can loosely organise transmitters into the following types: 2.4GHz, AM or FM (and may use PPM - pulse peak modula.tion or PCM - pulse code modulation).
With 2.4Ghz Transmitters they use spread spectrum technoology. Spread spectrum allows many pilots to transmit in the same band (2.4 GHz) with little fear of conflicts. Receivers in this band are virtually immune to most sources of electrical interference. You can read more about the different variations applied to spread spectrum technology by following the links to the sites below:
Rather than pontificate about what transmitter you should be using, here is a list of likely worthwhile contenders. Only suggestion here is go for 2.4Ghz.
