Futaba -hitec question
 

I just ordered a futaba 4pls and a 304sb Rx and I'll prolly also be grabbing a 204gffe Rx. I spoke to futaba support and they say some servos may not work with it. They can't say for sure unless it's a futaba servo. But I have a friend that runs a Savox servo with the 4pls with no issues so I got one of them for one truck. I want to get a hitec 7954 for my other truck but don't know if it will work ok with the futaba stuff. I assume it will cause it's digital
But can anyone say for sure that It will from experience?
