does a hitec hs645mg a direct replacment on a tc4? or will i have to buy diffrent servo arm?

It will physically fit, but you will need the Hitec servo arm.

Although the 645 is not a good choice for touring. It's slow, and the extra torque is unnecessary. It also has a terrible reputation for quality - certainly I've never had any luck with Hitec stuff.

Throw out that hitec servo, and get a Futaba. I bought an HS-985MG, and it was junk. It couldn't even center the steering rack. So, I bought a Futada S9351 to do the job. And its been working for me, with no problems.
