All the Horizon Sticks have right thrust built into the firewall. If it's not there, then you will find that the motor mount sets the right thrust.

Most planes trim out better with a touch of right thrust. It helps overcome the left turning tendency (torque) of the engine when going from low to high throttle settings.

Don't worry about the right angle. Horizon did an excellent job in the design and manufacture of the Stick line. They fly very well and are quite forgiving for the newer pilot when the flight surfaces are set correctly and are flown at reasonable speeds.
