If i understand you want to release sky diveres for a fun fly or other event like that, if so what you need to do is mount them on the cg and as close so the center of the wing as possible (if its a low wing right in the middle of the fuse if its a high wing plane mount the 2 guys on the fuse inline with the cg so that cg will not change your trim probably will because of the realaes of wight and drag,

paradrop:
If you are planning on dropping one or more skydivers you should plan on a aircraft of six foot span or larger and a motor size of a good 60 or 90 engine most jumper when ready to drop range in the two and half pounds to three and a half pounds. I have four skydivers and they all weigh three and a half pounds. my buddy drops mine and his jumpers from a senior kadet with a 60 OS on it and it does a very good job of lifting the two divers. You will have other pilots reccomend other planes and motors all this will be good advice because they like me have thier own preference but you will have to make the decision of what you want yourself good luck and hope to see pictures of your diver when you get to jumping.

On real jump planes, the jumpers usually actively assist the pilot in maintaining CG, by scrunching forward as a large group is in the door.

Not so important on small Cessna types.
Very important on a Queen/King Air with their high wing loading.
Pretty important on an Otter with the far rearward door.
A Porter can handle almost anything unless there's a real "meat load" parked on the back seat and nothing in front.
With tailgates - Skyvan is CG sensitive, CASA less so. Both still require jumper cooperation though.
