The Hitec 5245 coupled with a 4-40 Carbon nyrod and ball links would work extremely well for your application. The Karbonite gears used in the 475 are not recommended in gas applications due to vibration issues. A good quality servo and linkage are recommended for 3D due to needing very precise throttle control.

What is the source of the advisory and what is the issue?

Hitec used to post this info on their support page, but I don't see it now. They had some issues with Karbonite gears failing due to heavy vibration in giant scale as well people using locktite. Their advise was to use only metal geared servos in giant scale. This is also the advise given by Troy Built Models website. I would probably go the 425 route over the 475 route for that reason. The 5245 is a much better servo the either of them for the application in question.

Thankx for input,

I was told that the 5245 would be a good set up for throttle due to its metal gear and fast transit time. I was going to put a 5625 in like in my 27%, bipe but transit time is slower. I just wanted to see if any one had problem's with them. Now after some research I am finding out that they are pretty good! There is a lot of people on rc group's running them in electric's as elevator servo's. Thankx again
