I just used ball bearinv servos for mine. I'm not a 3D pilot and don't really wring out a plane. I haven't flown the Paramount yet, but it is finished and ready to go.

I did move the throttle servo; made a mount right behind the tank. It wasn't as easy as I thought, had to adjust for the wing.

I then put the rudder servo in the location left empty by the throttle servo. I had to shave some of the wood on one side to get it closer to the center. I also put a longer servo arm on so I needed it closer to center for it to have enough room. I used some spare ply to raise it a bit, don't remember what size it was.

Since I had the extra room I put a longer servo arm on for the elevator also. I used the Dubro heavy duty arms on all of the surfaces. Not for strength but for the longer throw they give.

I could have sworn I took photos of all the work I did but can't seem to find any. I'm recharging my camera now and will take some when it's done. I recently swapped everything over to a new pc so I may have lost them in the move. I have a digital camera so taking photos are cheap, no big deal.

Let me know if you have any more questions.
