Advice on Futaba 4PL vs 4PKS vs any other

[cutting42]

Hiya

I am getting back into RC racing via my son. He is kitted out but I have bought a B44.1 and have a couple of local clubs to race at. One astroturf outdoor and one indoor carpet.

I want to get a decent 2.4Ghz radio system and have heard great things about Futaba. I have the chance to get a 4PL for about 130 quid or a 4PKS for 180. Is the 4PKS worth the extra and would I see a benefit for what I am going to use them for?

Also am I spending too much and would a much cheaper Flysky/W6/Spektrum etc do the job for less?

Any help much appreciated.
