Questions about FT Guinea Pig CG tollerances

[Cnat]

I just finished building my FT guinea pig. Hoping to maiden this week. I was curious how much weight you could put in the cargo bay without throwing the CG off too much. Has anyone played around with dropping anything like water balloons out of the cargo bay? I've also got 2 bomb drops on each wing i could drop heavier stuff with. I just thought being able to drop a bunch of water balloons from the cargo bay would be a good time.

Thanks!

...how much weight you could put in the cargo bay without throwing the CG off too much....

It's not so much how much weight but where the weight is. You are going to need to keep the added on the CG so as to not move where the plane balances. A 1/4 inch change in where the CG is can drastically change how the plane flies.
