A bit off topic from the current postings, I was wondering if there is a huge difference between the Pro Module Tx/Rx sets and the Original Set of Tx/Rx?

The reason I ask, I currently use a M11 with the original set of Tx/Rx on my electric TC and nitro TC. Although I had to swap out the Rx on my electric TC with the micro series to fit my BL set-up (Novak GTB...haven't had any issues with it, in relation to what was being discussed on the previous posts) and alot of my race buddies who also use the M11 have been switching over to the Futaba 3PKS 2.4ghz FASST system and said the system is quicker that the previous Tx/Rx they had especially on their nitro TC...

I've thought of doing the same as well but I have invested so much on the specktrum Rx (coz I currently have 3 cars) and spending a lot of $$$ just to switch is not my plan. I thought of just getting the Futaba Tx only & purchase the spektrum Tx/Rx set that was released ($350 - $400) or just get the Pro Module Tx/Rx set for my M11 ($140 - $180). I'm leaning towards to just get the M11 Pro Module set since I don't need to purchase another Pro series Rx coz I already have the mirco on my electric TC.

Would the upgrade to the Pro Module set for my M11 be better than my original set-up and also is it comparable to the Futaba 3PKS 2.4ghz FASST system?

Thanks for any help you guys could provide.
