Hi, Henry and Tam.
I have used the Ex10 for a long while and had been using the Ex1 UR for a month or two (while switching back to my Ex10 from time to time). Personally, I think it will be a little difficult to tell whether any difference is all contributed from the new transmitting format(2.4G vs AD band) or it is mainly from the transmitting format.
Given the exact same car and the same AD band module, there certainly are differences between the two remotes. Ex1 UR has a much much lighter steering wheel and the the throttle trigger, even when my Ex10 is tuned all the way loose (unless some Bros had cut the spring, that will be a different story). Of course, positions of where things are, weight, grip are all different too...So even the first drive with Ex1 UR, I could feel the difference in car performance just by the physical differences between two remotes.
I recently just gotten my 2.4G module and on-car 2.4G board; and I will test on both Ex10 and Ex1 UR, without using the new Ex1 UR features (such as quick response or quick throttle), and compare it to my second AD band car which has a very similar setup.
Another question I have is whether it is not a remote question, but mainly the new 2.4G on-car board is a better design than the AD band board. All I know so far is the ICS setting will be different and that will certainly affect the car.
I too am not a signal expert, but I think Tam is asking the right question--as far as I know, even with 2.4G (a transmitting format) , the signal could be transmitted in either PCM or PPM (encoding format). It is probably important to understand their differences while we are making the comparisons in reality. But one thing for sure, with the spread spectrum, we will definitely have less radio-related (Tx or Rx) problems.
To kick-off, I found an interesting read for anyone who likes to learn more:
