PPM - PCM - HRS
Hey guys, i have some questions. In a month, i will have my future 4PK 
I was browsing a little untill i come along with these parameters. What is PPM, PCM and HRS? I don't have an idea. The 4PK has the ability to change between these 3, but which is most suitable for me? What are the advantages and disadvantages of each one, and what are you using now? Which is the best?

HRS uses Futaba's Spread Spectrum technology, one catch though you have to use all digital servos. If you use an analog servo in HRS you will kill the servo, HRS is Futaba's High Response System which is the only mode that permanently stores your servos fail safe position.

So HRS would be the best choice? What do you mean failsafe position? They are gonna stay in the position the last time were? That's bad if you were in full throttle

HRS originally was used with PCM mode, but now, with 2.4GHz in use by Futaba, HRS also exists in the 2.4GHz signal transmission as well.
