Nope.

By the looks of it tho, you should have plenty of power with those servos.

You may want to look at something a little faster though.
I'm using HS-6985

Torque 4.8/6.0v : 144/172 oz.
Speed 4.8/6.0v : 0.16/0.13 SEC

I used one on the collective of my Raptor 90 all last year and there is still NO PLAY in that servo what so ever.
I was so impressed, I went and picked up 2 more for cyclics.

I have a friend who uses the non digital version of that servo (645mg) on collective on his Rappy 90, and it works very well. He flies pretty agressive 3d, and it has good punch, although a slightly faster servo might be better. I'm using a Hitec HS 6975HB on collective on a Freya, and it is about the best collective servo I've tried, very strong, fast, and precise. Certainly better than the 5645, I think it's worth the extra $30.

I'm using 5625 (same as 5645, just the gear ratio is different) in my 2 R50 colletive. One has more that 200 flight and the slope on the metal gears is almost imperceptible.

On my Freya Evo 90 I put the 6975 on the collective (6965 on ciclic). Plenty of authority and very fast.
