Designing the entire radio around this allowed them to use less battery power to brodcast the signal.
BTW. I have noticed no range loss on batterys that were just about to die. It has a low voltage alarme you can set. I have mine set to start beeping at 4.1v and it seems to still have the same range as with freash batteries. I havent pushed it to find out exactly what voltage it stops working at though.
I can sure tell you that comparing this thing to my old M11 made the M11 feel like holding a brick. At first it felt wierd that it was so light, but now that Im used to it I picked up a buddys M11 and I couldnt believe how heavy it felt.

I just picked up an M11 and a pair of m8s. I like the feel and features of the m11, much better than my futaba 2pl and 3pm. I have a spectrum module and a couple of novak switches, and a bunch of novak synth receivers. I plan on running mainly fm, but will run spectrum on my top speed project. I have had great success with fm, did notice that my 3pm had much better range than my 2pl. I have not had much time to test the m11 yet, off the bench. It is really easy to set, even mixing channels and setting all of theother cool functions! Had to glance at the manual a few times...
I can see the benifit of 2.4 when racing, no need to lug around a bunch of crystals! I would buy a new radio, but I have only spent about 600 bucks on the 3 radios and about 20 receivers...
