you do realize that when you use a amp with higher RF power output your battery life is much lower, right? let's do the math ...

100mW output power, consumption maybe around 300mW. 2Wh battery will last 6h.
500mW output power, consumption maybe around 1W. 2Wh battery will last 2h.
2000mW output power, consumption maybe around 4W. 2Wh battery will last 30 minutes.

Given the same battery on your 72 and your 2.4 system, the 2W mod will run your battery low 12x faster than your 72 system. The 500mW will run it low 5x faster. Did you know that a power amplifier costs more than a new battery?
