radio for RC8Be
 

Hi
I need to purchase a radio. I am building a RC8Be. I am new to rc. I have 3 rc cars. I'm looking at a futaba 4pl and a 4pks. The 4pl is less expensive.
Which radio is more compatible with more receivers?
Is it worth the additional money to purchase the 4pks?
Will I get the most out of the 4pks or should I start with a less expensive radio and work my way up.

Any help will be great.
Thanks
Peter

Both radios allow you to control up to 40 models. I have the 4Pk, I love how it feels and the features it has. And Ive always loved the look.
