Default TRex 450SE and Spektrum DX7 DS821 servos

Hi,
I just got a Spektrum DX7 system with the DS821 digital servos.. My question is: Can I use these servos in my TRex 450SE?

Thanks,
Maurice

Arent they too big to fit the fuselage mounts?
And isn't the speed rather slow for the tail?

those are full size servos....so No you cannot use them


I have Jr 281 digitals (with metal gears) and those work nicely.... but probably the best setup is HS-65's

What about the servos from the DX6? Would they work if you just wanted to get up and running?

Just wondering if it would work. I know that they would not be as good as a hs56 or similar, but hey. Som of us are on a budget and will have funds available later.

I used the S75's from my DX6 at first. They don't center well and have slop, flight was mushy. After switching to HS65's the difference was immediatly apparant. Use a digital servo on the tail, I have a Futaba 9650/401.
