Any plane will climb with flaps deployed - After all, they ARE designed to create more lift. But after an initial "balloon" when deployed, allow the plane to settle into its new configuration and see how it feels.

Most of the planes I have used flaps one require nothing, but I have had a few (and only a very few) that did need about 6-8% of down elevator mixed in.

Without the down trim, they flew very "floaty". Sort of a nose-up attitude and on the verge of a stall. With increased power to prevent a stall, they tended to climb - not what you want when you're trying to land.

So just a tad of down keeps the nose pointed in the right direction.

But you'll have to fly it first to see how your particular plane handles.
