Virtually all full scale planes with a radial engine have both right and down thrust. Go look at a T-28, for example. The old WW II fighters has big engines with lots of torque and they had right thrust.

Most of the older pattern planes from the 1970s had right thrust. We used old cross flow engines with more torque than horsepower and swung fairly large props. When tuned pipes came into vogue, we went the smaller props for a higher speed so we quit using right thrust. With the advent of large props, some use of right thrust came back. Nearly all 3D planes have, or need, right thrust. The slow speeds, long props make the plane want to pull left so right thrust is needed to compensate, if you want your plane to fly well. Certainly, you can hold rudder, but it is better to use the right thrust.
