Is the right and down thrust built into the firewall or do you have to put it in? And if you do how?
Because of the airfoil used and the nature of this model, you really don't need to concern yourself about having right thrust or down thrust. A little down thrust wouldn't hurt and neither would right thrust, but I doubt you will notice its absence if there isn't any there at all.
