Your flight sounds OK, and trims sound as expected.

Try a nice 60-80% level power pass over runway and climb into a 45 with good speed, roll inverted and neutralize sticks.
The plane should keep its heading and slowly arc back down,
If it actually climbs hands off ( unusual), it would be quite tailheavy.

Cruise level and roll inverted, if you just need a touch of down elevator, you are likely in a good range. If it requires a steady down elevator input because it wants to hit the runway, you are nosesheavy.

This only applies after you have manually trimmed and adjusted incidence and servo travel on the ground.

Your CG is likely close as you are flying it, after all.
Do the other stuff before making any CG changes.
