i picked up a nitro rc car that had some new hitec servos in them and wanted to steal them for my ultrasport..one is a standered hs-311 and the other is a deluxe hs-425bb any ideas if these would work or not?...also could they be pluged into any old reciver and still work right like a futaba, just wanted to ask before i lawn darted my ultrasport lol

They should work fine, just that Hitec and Futaba rotate in opposite directions with the same input but that should be no problem as you can reverse the direction of throw at the transmitter.

thanks for the help. i think im going to throw it in as a rudder and throttle servo untill my new ones get here

I'd recomment using the 311 on the throttle and the 425 for the rudder. But you probably already knew that.
Good luck and enjoy the flying.
