Both are fine radios....both have had, notice, I said had, their problems...Futaba was a heat issue...and Spectrum/JR had a couple of recalls.....
Me I am a Futaba guy......mostly because that was the first radio system I owned......If you dont know, Spectrum's charge jack is wired backwards of eveyone else's. Do not use a Futaba charger to try and charge your new system.....plus when you get more advanced Spectrum's expo settings is positive for a softer center while Futaba is negative.......
Spectrum has model match.while Futaba simply has modle memory.....
When I move to 2.4 I plan on going with the Futaba 10.........but like I siad both systems are fine
