I am looking for my first 2.4ghz radio system for my driveway RC racing.
Is futaba 3prka the best thing in that price range or should I spend $30 more and get 3PL instead? Will I be able to pair multiple receivers with 3prka?
I also looked at airtronics mx sport but additional receivers cost $70..
Thx.

Yes, you could pair multiple receivers with the 3PRKA but w/o model memory and digital trims, using it for multiple cars would get to be a pita in a hurry because you'd have to re-set everything on the transmitter by hand everytime you change cars. The 3PL's 10 model memory should be more than enough for most people.

Radio's are something you keep for a Very Long time *If your Treat your Gear with Care. So look at it as an Investment. A 300$ Radio Now Wont seem like such a Big deal a Couple year's down the Road. If Rx Prices seem High, well that's part of the 2.4 swap over. were not back in the 90's Running AM/FM Crystals so lets be thankful of that.
