Even a few ounces are enough to cause a servo to work to maintain its position. It’s just good design to mount the CG of the assembly close to the pivot point by design, rather than doing it as a stop-gap to keep the servo from throwing teeth when you hit a bump.
Generally speaking, if you can hear/feel a servo when it’s holding position, then it’s under load, and doing work to keep it there.
Heres the latest model. I still have to fix the pivot point of the gun and add the CAM system…not sure how to do that.

UPDATE: im considering using a 2 servos on the tilt part of the Gunner becuase I dont want to loose the position it is in now, even if it is a little top heavy. I think two servos will split the load and there wont be a problem. Also, the CAM will most likely use a small motor, i dont know which one yet. Any suggestions? Thanks.
EDIT: Im thinking this one is good: Link
But IDK where to get 3mm hubs??
Actually I think a mini servo would work better: Link
A question I would have is can the pistol be operated on its side or up side down? If so the mounting might be easier/better. Also, the trigger can be operated via a servo fairly easily if desired.
Well its not like a water gun silly. 
Ive used these types of guns before and I know how they work fairly well. Im sure this setup will work good for me. Once I begin testing it after a simple first build, I can see how I want things mounted.
That being the case, how come you can’t answer the question weather they can operate on their side or up side down?
I did, the answer being “its not a water gun silly” 
Meaning it can operate fairly well upsidedown and on its side. Though shooting on its side is actually fairly unsafe as it increases the recoil and will come back in hit you in the face if your not careful. That being said, its not a good idea to have it in that position which is why I suggested to keep it the way it is. Now, my friend has several battery operated soft pellot pistols, i think ill start with those ones. They are fairly similar however, they are much less powerful.
If you are trying to mount a weapon that has sufficient recoil to hit you in the face, then I think you are trying to do something that will eventually get yourself or somebody else hurt. Stick with the low/no recoil plastic pellet pistols.
I have no intensions going out of these limits. You miss understood, I was talking generaly of all “guns” recoil being increased by the fact that they are sideways…Using ammunition that has great recoil would be dangerous, using pellot guns is merely robot fun 
It won’t have more recoil or blowback from being on it’s side. Nor do real guns.
There are some real cheap airsoft pistols that actually gravity feed from a hopper in the top of the gun. Just be sure it isn’t one of those. I haven’t seen many, but there are a few.
Yeah I have seen those airsoft with hoppers and they’re brutal.
Hmm…from what I remeber when an officer came to our school to talk about weapons he mentioned that shooting sideways (like in the movies) is the worst thing to do becuase the gun pulls back from recoil and will hit you in the forhead. Im rethinking the whole “increases recoil” statement, but thats what I remember…
Just considering basic physics:
Recoil is just thrust, which is off-center in relation to the pivot points of your joints, since the barrel is offset above your hand. In an upright configuration, it’s pushing both itself and your arm against gravity. In a sideways configuration, aside from just looking like you’ve seen too many gangsta movies, the thrust is to the side, and it’s only fighting the inertia of the weapon/arm combination. The thrust doesn’t change, but the resistance that it has to overcome is lessened, thus you perceive that it kicks more when sideways than when held properly.
The same would apply to paintballs, airsoft pellets, BBs, or sucker-darts, except that significantly lower levels of thrust are involved.
Thats the way he put it. It was just hard to memorize what he said. And yes thats why I mesntioned it about “all guns” because it is an affect that can happen from almost any wesapon. Thanks.
Like Seamus said, it doesn’t actually recoil more. But in relation to your hand, it seems to kick more. Mounted to a pan/tilt, it wouldn’t make any difference.
Pulling a trigger can be as simple as using a servo and a paper clip. Below is a simple thermostat controller I made some time back. The same setup probably could be used to pull a trigger. The ease of doing a trigger pull would probably depend on how the ssc-32 handles servo position input commands. Getting back to tracks, I think it would be interesting to see who can make a workable (but not necessarly pretty) set of ~12" tracks for less than $10 using locally available parts and simple tools.
Whos up for the challenge?
I might be. I’m thinking of using mostly wood as it is cheap, fairly easy to work with and the tooling used would be affordable to those on a limited budget. It would also require persons to actually undersand how tracked systems operate. Definaely a good learning exercise.
ZoomKat: Your bird stopped.
I think that wood would work great providing you covered it in a type of mesh and resin so it dosent wear out outdoors. Idk it would be to expensive, just some metal screening and carpenters glue. I might consider doing this myself as a learning experience. YOUR ON! lol
I also noticed that, perpetual motion my foot!
