Goldfinger found out that you get more aggressive steering if you mount it on the top. Less agressive and steering throw if you mount it at the bottom.

Julius mentioned that there is a reason why they are mounted below the servo saver.

I tried it the last outing and I could notice the difference. The aggresiveness of the steering is gone and instead you get a smoother and more controlled steering in and out. Perhaps you might want to try it out for yourself to see which you like.
