Welcome to the forum. I'm surprised that the building plans didn't explain how to set the CofG, it is the most important setup of any new aircraft along with the centring of the control surfaces. Always climb to 2 mistakes high, around 50ft before levelling out, it gives you a bit of time to get the aircraft under control if it's flying like a dog.
Good luck with the next sortie.
